Checklist of Basidiomycota and New Records from the Azores Archipelago

Abstract

This paper presents an annotated checklist of the Basidiomycota taxa (including lichenicolous fungi and the subdivision Pucciniomycotina) from the Azores archipelago and reviews the published records to account for their taxonomic status. The number of Basidiomycota species recorded in the Azores has increased considerably during the 20th century and now stands at 544 species. This study provides distribution data and includes changes in the nomenclature of the listed taxa. Sampling campaigns contributed to 116 new records of Basidiomycota for the Azores archipelago. In addition, there were new records for eight islands: 162 species found for the first time on São Miguel Island, 55 species new to Santa Maria Island, 33 species new to Flores Island, 15 species new to Terceira Island, 9 species new to Pico Island, 17 species new to São Jorge Island, 4 species new to Graciosa Island, and 2 species new to Corvo Island. The transformation of vegetation cover in the archipelago has been very drastic, and this is reflected in the presence of many foreign fungal species on the islands. From these data, we conclude that within Macaronesia, the diversity of Basidiomycota in the Azores is more similar to that in Madeira than in the Canary Islands.

1. Introduction

Basidiomycota is the second largest phylum of the kingdom Fungi, with ca. 41,000 species [1] that, together with the Ascomycota, constitute the subkingdom Dikarya. From an ecological perspective, Basidiomycota encompasses great diversity, from ectomycorrhizal mycobionts to pathogens and saprophytes, and they are key players in ecosystem functioning at multiple levels, including nutrient cycling, carbon cycling, and as a food source. Basidiomycota exhibits worldwide distribution, but previous studies point to a higher species richness in temperate regions, although tropical areas have received comparatively less attention [2].

Little is known about Basidiomycota diversity in oceanic islands, and the Azores, located in the North Atlantic Ocean between 36° and 43° north latitude, offers a unique opportunity to study this group of fungi, with its humid climate and dense and lush vegetation that in many parts of the different islands can still be considered pristine. Within Macaronesia, a biogeographic region that includes the Azores, Madeira, the Canary Islands, and the Cape Verde Islands, only the Canary Islands and Madeira have been the focus of interest for many mycologists [3,4], while the Azores and Cape Verde have been less studied. In the Azores, the most updated checklist cites 312 Basidiomycota members [5], of which approximately half belong to only two orders, Polyporales and Pucciniales.

The study of terrestrial fungi in the Azores archipelago dates back nearly two centuries to the investigations carried out by Drouet (1866). Drouet’s visit to the archipelago in 1857 resulted in an extensive inventory of vascular plants, algae, mosses, and fungi. However, in the fungal section of Drouet’s work, only 2 species of the genus Peziza (Ascomycota) were reported, along with 41 lichen species [6], without ever mentioning any taxa belonging to Basidiomycota. Subsequently, during the years 1872 to 1876, the H.M.S. Challenger expedition explored the Azores archipelago and contributed two additional fungal species to the knowledge of the region: Bovista plumbea Pers. and Agaricus crenatus Lasch [7]. Later, after reviewing the exsiccata of Agaricus in the Kew Gardens, Dennis et al. [8] eliminated it as having been unreliably identified and concluded that it was most likely a Stropharia. Another contribution to the funga of the Azores was made by Trelease, who visited the archipelago between 1894 and 1896. Trelease’s botanical collection, titled “Botanical Observations on the Azores”, included a list of 22 Basidiomycota species [9]. Among these species, only four can be classified as macromycetes, while the remainder comprised rust fungi.

In the first half of the 20th century, the few available studies were focused on Pucciniales, with a contribution of 12 taxa [10,11,12], and 7 taxa of Polyporaceae [13]. Almost half a century later, the mycologist R. Dennis visited the islands in 1975 to conduct a sampling campaign and compiled bibliographical information, resulting in the first comprehensive list of fungi for the archipelago, with 141 species of Basidiomycota [8].

The concern for plant pathologies produced several works on fungal pathogens in the Azores [10,14,15]. The first Uredinales checklist for Macaronesia summarised all the works on rust fungi [16], and the complete fungi records mentioned in those mycological studies were later compiled by Spooner & Butterfill [17]. Subsequently, from two collections made by the Kew Gardens (in April–May 1995 and October–November 1996), studies were carried out on Uredinales and Ustilaginales [18] as well as Heterobasidiomycetes [19] and Poroid fungi [20].

Since then, mycological contributions have been sporadic, except for the extensive work carried out on corticioid fungi s.l. [21,22,23,24,25,26,27,28,29,30,31]. The most recent compilation of Basidiomycota in the Azores, a list of 307 taxa, was published by Melo et al. [5] as part of a work on the terrestrial and marine biota of the Azores [32]. After that, Calonge & Mir-Pegueroles [33] reported 28 new species of basidiomycetes for the Azores, and the last work corresponds to the identification of 118 species on the island of Terceira [34].

Despite increased research efforts, especially in the last decade, knowledge of the diversity and distribution of macrofungi in the Azores Archipelago is not consistently organised. This study aims to address this gap by presenting an updated checklist of macrofungi found in the Azores. The checklist is based on a taxonomically revised compilation of previously documented species from preserved samples and new collections from various islands, including São Miguel, Terceira, Flores, Graciosa, Pico, São Jorge, and Santa Maria. The aim is to provide a more accurate representation of this group of fungi and to compare the results with other parts of Macaronesia.

2. Materials and Methods

2.1. Study Area

The Azores is an oceanic archipelago located in the Mid-Atlantic Ridge (Figure 1) that is composed of nine volcanic islands divided into three groups: the western group (Corvo and Flores), the central group (Faial, Pico, Graciosa, São Jorge, and Terceira) and the eastern group (São Miguel and Santa Maria). The climate of the Azores is temperate oceanic, with regular and abundant rainfall. Annual rainfall average ranges from 740 to 2400 mm [35,36], causing high relative humidity levels (up to 95% in the high-altitude native forests). The thermal variations are moderate throughout the year, with annual temperatures between 14 and 18 °C [37].

Native laurissilva forest cover less than 10% of the total area, mostly at elevations > 800 m above sea level [38]. The dominant tree species in this endemic forest are Juniperus brevifolia (Seub.) Antoine, Laurus azorica (Seub.) Franco, and Ilex perado Aiton, with a closed canopy in which a great diversity of ferns and mosses are found (e.g., Culcita macrocarpa C. Presl, Polytrichum juniperinum Hedw., and Sphagnum spp.). Small patches of this laurissilva still occur at higher altitudes, where anthropogenic pressure is smaller, especially on the Terceira, Flores, and Pico islands.

According to historical sources, the archipelago was discovered and colonised by the Portuguese in the fifteenth century. Still, recent works point to a much earlier occupation (ca. 700 years before), probably by the Norse [39]. As populations settled on the islands, they forced extensive, long-term changes to the native vegetation composition and caused landscape destruction [39,40,41]. Throughout the centuries, the Azores have been drastically deforested to create space for agricultural fields, supply energy for people (charcoal), and facilitate and implement infrastructure and construction [42], leading to the destruction of more than 95% of the Azorean natural vegetation [43]. Due to the lack of wood and increasing soil erosion, Cryptomeria japonica (Thunb. ex L. f.) D. Don was introduced and now occupies about 22% of the area of the Azores (representing 60% of the forest plantation area), mainly at elevations > 400 m above sea level [38]. The other allochthonous trees that occupy most of the territory are Pittosporum undulatum Vent and Ocotea foetens (Aiton) Baill. formations. Small patches of Eucalyptus, Pinus, and Acacia spp. occasionally appear on different islands. All these changes have had an enormous influence on the current funga.

2.2. Sampling Sites

Sampling was conducted on eight islands (Figure 1 and Table S1 in Supplementary Materials). São Miguel island has been the most-studied island, as it is the largest, most populated, and has higher habitat heterogeneity. Twenty-five sites were sampled on this island (Loc. 1–25), encompassing a range of vegetation types. Low-impacted areas covered with native vegetation, such as Serra Devassa (Loc. 21), Planalto dos Graminhais (Loc. 22) and Pico da Vara (Loc. 24), were characterised by Juniperus brevifolia montane forests associated with open bush in mosaic with wet heathlands, with very rich flora including Erica azorica Hochst. ex Seub., Calluna vulgaris (L.) Hull, Ilex perado, Vaccinium cylindraceum Sm., Myrsine africana L., Culcita macrocarpa C. Presl, Polytrichum juniperinum Hedw., and Sphagnum spp. Sampling sites in semi-forested landscapes were characterised by allochthonous tree species, such as Araucaria, Liriodendron, Magnolia, Camellia, and Platanus, among others (Loc. 17, 20). Additionally, forest reserves containing economically valuable tree species and botanic gardens were also sampled (Loc. 5–Loc. 8). The remaining sites were distributed across lakeshores, pastures, and wooded areas, where C. japonica (Loc. 14) and Pittosporum undulatum (Loc. 12) were the predominant species.

Six sites were sampled on Terceira Island (Loc. 28–Loc. 33). The upper and central parts of the island were characterised by well-preserved native vegetation and abundant peatland areas, such as Lagoa da Serreta (Loc. 30) and Serra de Santa Barbara (Loc. 31). Within impacted areas, patches of Eucalyptus globulus Labill. (Mata da Serreta, Loc. 29), Metrosideros excelsa Sol. ex Gaertn. (Ponta do Queimado, Loc. 28) and Pittosporum undulatum (Biscoitos, Loc. 32) were sampled. On Flores Island, five sites with diverse habitats were selected (Loc. 36–Loc. 40), including the peatland area of Caldeira Branca (Loc. 38), the native vegetation patch at Morro Alto (Loc. 40), and the forests of Pittosporum undulatum in Fajã Grande (Loc. 37) and Lajes das Flores (Loc. 36). Another five sites on Santa Maria Island that differed in vegetation cover, such as the Pinus pinaster Aiton forest (Loc. 43), a mixed forest with a predominance of Pittosporum undulatum (Loc. 41 and Loc 42), and C. japonica patches (Loc. 44 and Loc. 45), were sampled. Occasional samples in São Jorge (Loc. 26), Pico (Loc. 27), Graciosa Island (Loc. 34 and Loc. 35) and Corvo Island (Loc. 46) were also collected.

2.3. Sampling Methods

Specimens were collected mainly during the two main fructification periods (autumn and spring) in 2008 and 2019–2023. Each specimen was carefully georeferenced and photographed in its natural habitat, capturing important characteristics such as colour, odour, texture, growth habit, and substrate type to facilitate accurate identification. The specimens were processed using the traditional techniques of specimen collecting, and collections were preserved by convective warm-air drying.

Preliminary identification of the specimens was conducted in the field, using general literature references such as Bon [44], Courtecuisse and Duhem [45], and, later, by consulting specific key works for each group in the laboratory. Voucher specimens were deposited in the Herbarium of the University of Azores “Rui Telles Palhinha” (AZB) and the personal herbarium of M. Souto.

Macromorphological characters were observed in fresh specimens, while microscopic structures were examined in preparations of small parts of the basidiomata in 5% KOH. To enhance the visualisation of hyaline structures, Congo red staining was applied. Pictures were taken with a Leica DFC495 camera (Leica Microsystems GmbH, Watzlar, Germany) attached to a Leica DM2500 (Leica Microsystems GmbH, Watzlar, Germany) light microscope and analysed using image analysis software (Leica Application Suite version 3.8.0).

2.4. Checklist

The checklist was compiled by incorporating information from various sources, including literature, herbarium specimens, and field samplings. It is important to note that lichenicolous fungi (Basidiolichens) have also been included in the checklist, with references from Martinez [46], Berger & Aptroot [47], Aptroot et al. [48], Hafellner [49,50], van den Boom [51,52], Millanes et al. [53,54], and Diederich et al. [55].

The distribution is named according to the island from which each taxon was collected: SMG (São Miguel), TER (Terceira), FAI (Faial), PIC (Pico), FLO (Flores), COR (Corvo), STM (Santa Maria), GRA (Graciosa), SJG (Sao Jorge). Information such as specimen locality, island, date, collector (legitimavit), and habitat are included for newly collected material from field samplings. Distribution and references (Dist. & Ref.) for each species are listed chronologically by publication year and then by author. Species that are reported for the first time for the Macaronesia region are indicated by three asterisks ***, while those new to the Azores are marked with two asterisks **, and newly recorded taxa for a specific island are denoted by a single asterisk *.

The status and synonym of each species in the checklist follow the Index Fungorum databases (http://www.indexfungorum.org, accessed date 1 June 2023). Vascular plants and mosses were cross-checked according to http://www.theplantlist.org (accessed date 1 June 2023). To simplify the list, basionyms and synonyms have been excluded. Infraspecific taxa, such as varieties, were also not considered and were listed as binomial names. Basidiomycota classification follows Matheny et al. [56], He et al. [1] and Justo et al. [57] for Polyporales. The taxa are listed in alphabetical order by genus, species, and major taxonomic groups. The taxa with uncertain positions (incertae sedis) appear at the end of each taxon in the checklist.

Available digitised voucher specimens were consulted from different Herbaria (

) through MyCoPortal online database (https://www.mycoportal.org, accesed on 1 June 2023). Specimen names in the MyCoPortal linked to observation-based sources (e.g., MushroomObserver, iNaturalist) are difficult to verify because these data are not systematically associated with specimens and therefore cannot be scientifically validated, as, in most cases, only photographs are available. We have decided to include about 10 taxa that we believe can be reliably identified from photographs, such as Laurobasidium lauri, Clathrus ruber, and Laetiporus sulphureus.

Metulodontia nivea (P. Karst.) Parmasto was excluded from the checklist, as this taxon was cited by Melo et al. [5] for the Azores based on the literature, but the only previous reference for Macaronesia is found in Dennis et al. [8] for Madeira.

To compare the mycoflora of the different Macaronesian archipelagos, a bibliographical update of the different works on mycology for each group of islands has been carried out, with the current checklists as the starting point: for the Azores [5] and subsequent additions [22,24,25,26,27,28,29,30,31,33,34,46,47,48,49,50,52,53,55,58] the Canary Islands [3] and subsequent additions [22,31,54,55,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104]; Madeira [4] and subsequent additions [26,54,55,92,105,106,107,108,109,110,111,112,113,114,115,116,117,118]; Cabo Verde [119] and subsequent additions [31,51,55,120,121,122,123,124,125].

3. Results

The presented checklist comprises 544 taxa of Basidiomycota, including lichenicolous fungi and the subphylum Pucciniomycotina. The total number of specimens collected was ca. 600, and more than 90% were determined at the species level. Consequently, an extensive array of taxa has been assembled, representing a substantial portion of the Basidiomycota orders (Figure 2). Our collections recorded, for the first time, 116 Basidiomycota species in the Azores, of which 33 taxa can be considered new for Macaronesia.

Among the islands, São Miguel exhibits the highest mycobiota diversity in the archipelago, with 321 species identified, including 162 previously undocumented species (see Figure 3), almost doubling the number of known Basidiomycota on this island. Terceira Island recorded 15 new species, increasing the number of taxa to 270. The number of Basidiomycota species in Flores also increased, with 33 new records, reaching 132 species. In Santa Maria, we added 55 new species to its mycobiota, resulting in a total of 70 species for the island. Occasional samplings conducted in Pico, São Jorge, Graciosa, and Corvo yielded 10, 17, 4, and 2 new records, respectively, for those islands. Consequently, the total number of mycobiota on each island increased to 99, 49, 44, and 9, respectively. On the other hand, Faial has not undergone recent field samplings and therefore maintains the number of taxa reported in the previous literature [5], with 104 Basidiomycota species already documented.

Since 1874, when the first basidiomycetes were reported [7], there have been few, albeit continuous, studies. In 1975, the first exhaustive list of the fungi of the archipelago appeared, with 141 species of Basidiomycota [8]. Since then, mycological contributions have been sporadic, except for extensive work on the corticioid fungi [21,22,23,24,25,26,27,28,29,30,31]. The most recent work corresponds to the identification of 118 species on the island of Terceira [34] (Figure 4).

The review of all these data gives us an updated overview of the Basidiomycetes in Macaronesia.

summarises the number of species for each archipelago; to structure the data more comprehensively, we have not broken down the subphylum Pucciniomycotina, the subphylum Ustilaginomycotina to the class level, and the subphylum Agaricomycotina to the taxonomic class and order level (we have arranged the orders from the most species-rich to the least species-rich).

Compilation of Basidiomycota taxa number in the different archipelagos of the Macaronesia region (the Azores, the Canary Islands, Madeira, and Cape Verde) from the bibliographic update showed a total number of 1877 Basidiomycota species. The Canary Islands was the archipelago with the highest number of recorded species (1415), followed by Madeira with 713 species, the Azores archipelago with 544, and Cape Verde with only 57 species recorded to date (Table 2 and Figure 5). The Sørensen–Dice Quotient of Similarity (QS) showed a certain degree of similarity between the different funga of the archipelagos with higher diversity (the Canary Islands, Madeira, and the Azores) (Figure 5). The Basidiomycota community from the Azores and Madeira shared many species, as reflected by the higher QS value (Figure 5; QS = 0.45). Moreover, funga similarity between Madeira and the Canary Islands produced a QS = 0.41, and the QS = 0.34 between the Canary Islands and Azores.

The ecology of each species was determined from the general bibliography for each taxon and the latest updated checklists for each archipelago (Figure 6).

4. Discussion

Forests are the main habitat of many macrofungi; consequently, modifications in vegetation cover are associated with an inevitable change in fungal diversity. Several studies show that deforestation leads to changes in the composition of soil fungi and reduces fungal diversity [130,131], especially among Basidiomycota [132,133]. In the case of the Azores, the original forests (laurissilva) have disappeared in many areas over large parts of the islands. The discovery and human colonisation of the islands have invariably resulted in their widespread ecological transformation [39,134]; the original forests (laurissilva) have disappeared in many areas and have been replaced by pastures and wooded areas dominated by allochthonous tree species.

Most of the sampling sites in the Azores correspond to forest areas (Cryptomeria and Pittosporum plantations). The high environmental humidity and the great diversity of dead woody debris in different degrees of disturbance explain the abundance of saprophytic species (Figure 6; 63% of the total species recorded). Large numbers of saprobic fungi, especially from the order Polyporales and several families of the order Agaricales, were recorded on wood or twigs and leaf litter. Mycena, Marasmius, and Marasmiellus are genera ubiquitous in these forests.

Numerous saprophytic species new to science have been described from samples collected in the Azores, such as Repetobasidium azoricum, Lagarobasidium calongei, Skeletocutis azorica, and Pseudotricholoma azoricum. These possible endemisms are associated with native species and laurel forests. The drastic deforestation of these ecosystems has led to the disappearance of numerous species of flora, fauna, and funga. Little is known about this last kingdom, and its study would be one more reason to protect the native ecosystems of the Azores.

Many of these allochthonous forests are populated by a dense undergrowth of ferns. Although Pteridophyta species are not a common substrate for fungi [135], some genera such as Athelopsis, Leptosporomyces, Luellia, Parvobasidium, Phebiella, and Tubulicium have been found in the autochthonous Culcita macrocarpa, and Woodwardia radicans or in allochthonous species such as Cyathea cooperi (W. J. Hooker ex F. von Mueller) Domin [24]. Much of the island’s native tree canopy has disappeared, but native ferns have regrown under the allochthonous forest species, creating a new hybrid habitat for many species of fungi.

Among the species that can be considered allochthonous, the helicosporous fungus Hobsonia mirabilis (Atractiellales, Phleogenaceae) has consistently been observed in multiple sampling locations across different islands, growing on the debris of various vascular plants, such as Pteridophytes or Monocotyledons (Hedychium), indicating its polyphagous nature. This species has been reported in tropical highlands, such as in the mountainous regions of Panama and Colombia [136], on Musa leaves in the Hawaiian Islands [137], on thistles in Japan, and in New Zealand [138]. In Macaronesia, it only appears in the Azores, and it is quite possible that its abundance is associated with the high dispersal of Hedychium gardnerianum throughout the archipelago. Hedychium is included in the list of the 100 most dangerous invasive alien species [139].

The drastic transformation of the islands from woodland to grassland has created the necessary conditions for the presence of numerous grassland saprophytic species such as Bovista, Coprinellus, Leucocoprinus, and Parasola. Many of these species are coprophilous and are associated with the strong presence of livestock in the archipelago. It is important to note the absence of mammals on the island before the arrival of man [39]. The large-scale expansion of these artificial grassland ecosystems associated with the strong development of the agricultural industry has favoured the dispersal of these species.

The second most diverse ecological fungal group in the Azores are the parasitic fungi, representing 25% of the total Basidiomycota species (Figure 6). A high number of lignicolous species, which initially act as parasites and subsequently complete their life cycle as saprophytes, has been observed. Among these are Ganoderma spp. and Armillaria mellea (Vahl) P. Kumm, which parasites many tree species. These parasitic fungi are particularly abundant on various allochthonous trees such as Pittosporum, Ocotea, and Cryptomeria. One of the causes of their wide dispersion is very likely to be the fact that many tree species are not from the archipelago, and although they belong to climatic zones very similar to the Azores, they are not in their optimum state, which makes them prone to numerous parasites.

Among the parasitic fungi, a great variety of species of the class Pucciniomycetes (rust fungi) is present in the Azores, probably due to the import of raw materials of plant origin, mainly cereals. Rust fungi are less pathogenic in drier areas [140], but the high relative humidity in the Azores has made them a significant subject of investigation in the archipelago [10,14,15,16]. Coleosporium Lév. exhibits a parasitic aecial stage on needle pines (Pinus spp.), while the telial stage occurs on a wide range of angiosperm species [141]. Three species are reported from the Azores: Coleosporium asterum (Dietel) Syd. & P. Syd. [18], Coleosporium senecionis (Schumach.) Rabenh. [9], and Coleosporium tussilaginis (Pers.) Lév. The latter species is widespread throughout Macaronesia. It is worth noting that the latter two species are considered synonymous since most researchers have combined various European taxa into formae speciales (ff. spp.) of Coleosporium tussilaginis [141]. These Coleosporium species are also allochthonous to the Azores, as one of their hosts, Pinus, is an alien species. Nowadays, many rust fungi, such as Puccinia hordei or P. striiformis, associated with cereal crops such as wheat are no longer so common due to the almost complete disappearance of cereal cultivation in the archipelago [42]; P. sorghi is somewhat abundant in the numerous fodder maize plantations. Nevertheless, two new records for Macaronesia stand out from this work: Puccinia cymbopogonis Massee, associated with the proliferation of the allochthonous grass species Cymbopogon citratus (DC.) Stapf. from Malaysia and Puccinia hydrocotyles (Mont.) Cooke, which parasitises a small peatland-specific hydrophyte, Hydrocotile vulgaris L.

Among the parasitic species, Eocronartium muscicola (Pers.) Fitzp. (Platygloeales, Eocronartiaceae) stands out (Figure 2), which represents the first documented presence of this species in Macaronesia. It is a parasite known to infest moss species and is primarily distributed in the Northern Hemisphere. It was found in a native Juniperus forest on Terceira (Loc. 30), developing a clavate Typhula-like fruiting bodies on the moss Eurhynchium praelongum. It has also been found to occur in Chile, parasitising the same genus Eurhynchium [142].

Eleven species of the family Tremellaceae have been reported as parasitising lichens or other fungi from Macaronesia [92], of which eight occur in the Azores. The humid climate may be one of the factors responsible for the fructification of most of the species of this family. Tremella laurisilvae Kout, with a parasitic strategy on Biscogniauxia species, a is a species new to science that was described from the evergreen laurel forests of the Canary Islands and Madeira [92] but has not yet been found in the Azores.

Diederich et al. [55] described a new genus of the lichenicolous fungi Crittendenia Diederich, Millanes, M. Westb., Etayo, J.C. Zamora & Wedin (Agaricostilbomycetes) from the Azores and the Canary Islands that comprise minute basidiomycetes of the synnemata type. This species was found in the Azores on the lichenes Bacidina, Byssoloma, and Hypotrachyna [55].

Mycorrhizal species account only for 12% of the total Basidiomycetes species in the Azores (Figure 6). Many of the ectomycorrhizal species observed in this archipelago are associated with introduced tree species, such as Boletaceae (Quercus, Pinus), Cortinarius, Amanita (Quercus), or Inocybe (Cryptomeria, Pittosporum). It is possible that many species of ectomycorrhizal basidiomycetes may exhibit invasive tendencies or possess the potential to become invasive. According to Vellinga et al. [143], most introductions of ectomycorrhizal fungi worldwide are associated with pine and eucalyptus plantations. Large stands of Amanita muscaria (L.) Lam. and Boletus reticulatus Schaeff. have been seen under Quercus palustris. Münchh. (Loc. 17, As Furnas, SMG) and it is known that these fungi establish associations with various tree genera in numerous regions worldwide [144,145]. Lactarius quieticolor Romagn., an edible fungus associated with pine forests (Loc. 1, Sete Cidades, SMG), is becoming increasingly scarce in the Azores due to the decline of pine populations in recent decades [41]. However, our collections of L. quieticolor under Cryptomeria (Loc. 45, Santo Espirito, STM) suggest that this species is spreading within plantations of this Japanese conifer. The expansion of many of these mycorrhizal species will depend largely on the future spread of their host plants and their preference for new autochthonous species.

The introduction of agricultural species and adventitious vascular plants from different geographical origins constitute a major impact on the native flora of the Azores [146]. Many of these endemic plant communities have experienced regression or irretrievable alterations as a result [147]. In the Azores archipelago, approximately 70% of the vascular flora consists of non-indigenous plants (about 1000 taxa of vascular flora) [148]. Large areas are mainly occupied by Hedychium gardneranum and the Caprifoliaceae Hydrangea macrophylla (Thunb.) Ser. In our field trips, we have observed a rapid expansion of two shrubs recently introduced in the Azores, one being the Asian Leycesteria formosa Wall. and one from Madeira’s Cletra arborea Aiton. Their expansion in the future will again affect these delicate ecosystems.

The impact of introducing fungi into native fungal communities is not well known [149,150]. Many fungi are now considered invasive species in large parts of the world, such as the well-known case of Favolaschia calocera R. Heim, which was first described in Madagascar and which has been recorded in numerous regions around the world [151], or Clathrus archeri (Berk.) Dring., which has a wide global spread [152]. The extensive alteration of vegetation cover in the archipelago facilitates the potential entry and dispersal of allochthonous fungi, but knowledge of them in the Azores is very limited. Favolaschia claudopus (Singer) Q.Y. Zhang & Y.C. Dai found under Ocotea foetens (Loc. 16) is an example of this problem; this citation is the first for Macaronesia.

Knowing the origin of the many species suspected to be allochthonous would be valuable. Some studies have used molecular phylogeographical analysis, such as that of Coetzee et al. [153], which demonstrate the allochthonous origin of the forest pathogen Armillaria mellea. Future work in this field could provide interesting results, as the archipelago is isolated from the mainland and is located halfway between America and Europe. Although there are species whose origin is quite clear, it is difficult to determine the allochthonous character of other taxa. Such is the case for Leucocoprinus birnbaumii (Corda) Singer, widely collected in São Miguel, which is a species typically associated with artificially heated soils, such as greenhouses and pots [154,155], and widely distributed in the northern hemisphere and subtropical areas [155].

Macaronesia Mycoflora

Previous studies have highlighted the similarity between mycobiota of Madeira and the Canary Islands [4]; however, our results show a greater similarity between the Azores and Madeira Basidiomycota (Table 2 and Figure 5), which is probably related to the fact that the Azores and Madeira show the greatest similarity in their flora and climate. Higher Basidiomycota diversity in the Canary Islands (Figure 6) may be related to them having the largest surface area of 7447 km² compared with 2332 km² for the Azores and 828 km² for Madeira. It may also be associated with the relative proximity to the mainland and the higher number of mycological studies in this archipelago. From a flora diversity point of view, the Canary Islands have greater similarity with southwestern Morocco, especially in habitats characterised by open sclerophyll forests and coastal dunes dominated by shrubs [156]. These floristic similarities, bioclimatic diversity, and geographical proximity to the mainland may explain the higher fungal species richness. Coastal zones characterised by sclerophyll forests (Juniperus spp.) and cardonales–tabaibales (Euphorbia spp.) are arid and semi-arid environments of the inframediterranean, presenting a specific diversity of basidiomycetes adapted to these arid conditions, such as the xerophytic Agaricales group [73]. Such coastal arid ecosystems are absent in the Azores and Madeira. In addition to the laurel forest (common to the whole of Macaronesia), the Canary Islands have large areas of pine forest and woodland with Mediterranean characteristics and a higher number of endemic taxa (ca. 680), almost 40% of all its vascular flora [157]. Because of this, the Canary Islands have numerous species of fungi that are endemic, ca. 20 taxa [3], as in the case of Gloeodontia xerophila Tellería, M. Dueñas, Rodríguez-Armas, Beltrán-Tej. & Melo, discovered on decomposing remains of Euphorbia.

The archipelago of Madeira comprises two islands: Madeira, the largest and with the highest elevation, and Porto Santo, which has a drier climate. Two more groups of small islets, the Desertas Islands and the Selvagens Islands, belong to the archipelago, the latter being located 280 km south of Madeira, closer to the Canary Islands. With 1204 vascular plants and 154 endemisms, Madeira has 13% of the endemisms [158]. All Basidiomycota of the Madeira archipelago have been collected on Madeira Island [4]. After the Canary Islands, Madeira Island has the highest number of mycological publications. From the eight Basidiomycota species described as new to science, seven were published by Torrend in the early 20th century [159,160,161] and have not been recorded since. It is necessary to consult these herbarium exsiccate to check the identification in a modern context.

The Azores have a slightly less diverse vascular flora than Madeira (1086 taxa/65 endemisms) [162]; however, the archipelago is made up of nine islands and, a priori, should harbour a greater number of fungal species. Of the 544 species catalogued for the Azores, 321 have been located on Sao Miguel (Figure 3), so it is necessary to reinforce sampling efforts on the rest of the islands. This heightened number of new records may be attributed to a sampling bias, as São Miguel is the largest and most extensively surveyed island, in contrast to the smaller islands of the Azores (e.g., Corvo has nine taxa). A similar situation is found in the archipelago of Madeira, which has numerous small islands with very few records, such as the Salvagens Islands, with three species; the Desertas Islands, four species; and Porto Santo, with eight species.

If we look at the number of species within the different orders (Table 2 and Figure 7), we can see that the biggest difference is in the Agaricales order. With 731 taxa, the Agaricales are the best-represented group of mycobiota in the Canary Islands (Table 2). If we compare many of the large orders of Basidiomycota with each other, we see less marked differences than in the case of Agaricales. This bias may be due to the extensive work done within the corticoid fungi s.l. in Macaronesia [21,23,24,25,26,27,28,29]. In addition, many rust fungi have long been described in a series of papers for the whole of Macaronesia [10,11,14,15,16]. In the case of the Azores, little attention has been paid to Agaricales, the largest order within basidiomycetes [1]. This lack of knowledge is evidenced by the fact that of the 116 new records for the Azores presented in this study, 86 are Agaricales, and 10 are Boletales. The largest contribution comes from the order Agaricales, where several families (Bolbitiaceae, Inocybaceae, Macrocystidiaceae, and Omphalotaceae) and within the order Boletales (Boletaceae, Diplocystaceae, Gyroporaceae, and Paxillaceae) are cited for the first time for the Azores.

Within Macaronesia, the archipelago of Cabo Verde has the most poorly studied mycoflora. Currently, the Basidiomycota catalogue of Cabo Verde is composed only of 57 species [31,119,121,122]. These islands are characterised by dry subtropical vegetation. The eastern islands (Boavista, Sal, and Maio) suffer long periods of drought together with a severe desertification process, presenting poor flora diversity. More than half of the species (27) belong to the class Pucciniomycetes [120]. Despite this, five species new to science have already been described: Hydnophlebia gorgonea Telleria, M. Dueñas & M.P. Martín, known from only two localities in São Vicente Island; Hydnophlebia meloi Telleria, M. Dueñas & M.P. Martín [31]; Cyathus lignilantanae R. Cruz & M.P. Martín, on Santiago Island [122]; and Rhizopogon granuloflavus M.P. Martín, M. Dueñas & Telleria [121]. Further south, the small archipelago of Sao Tomé and Príncipe has a basidiomycetes catalogue of 260 species [163], although this mycoflora is more tropical in character.

The understanding and conservation of biodiversity are hampered by a lack of information on taxonomic groups. Knowledge is often biased due to different sampling and identification efforts for each group of organisms. A clear example can be seen in the Azores, where several groups, such as the Agaricales, need to be studied in more depth. We need to study the mycoflora of the Azores further to have a clearer picture of the fungal diversity in Macaronesia, especially of the few remaining pristine ecosystems.

This work represents the first part of a project that aims to study the mycobiota of the Azores, and we are currently working on the other major group, Ascomycota. More fieldwork is needed to understand the fungi’s distribution and diversity, especially considering the great differences with other more-studied archipelagos such as the Canary Islands and Madeira. The checklist aims to serve as a baseline for more studies on the Azores. Still, this checklist is certainly incomplete, and additional future fieldwork will be necessary to complete the knowledge about this group of fungi.

5. Conclusions

This study represents the first comprehensive checklist of Basidiomycota fungi in the Azores archipelago. By compiling recent field sampling records and relevant literature, we have contributed 114 new taxa records for the archipelago, of which 33 are also new records for the Macaronesia region. The transformation of vegetation cover in the archipelago has been very drastic, and this is reflected in the presence of many foreign fungal species on the islands. While most new records were documented on the larger islands, increasing the sampling effort on the smaller and less explored islands is crucial to address the current knowledge gaps regarding the Basidiomycota group. These findings advance our understanding of global fungal diversity patterns. Furthermore, future studies should encompass the Ascomycota group to provide a more comprehensive understanding of fungal diversity and distribution in the Azores Islands.
