Special Issue Information

Dear Colleagues,

Forestry fungi, as the key decomposers in forest ecosystems, are rich in diversity. Extensive studies on the diversity of forestry fungi have been carried out recently, and many new taxa have been found from all kinds of forest ecosystems. The diversity and phylogenetic relationships of some important groups of forestry fungi are still unknown.

This Special Issue on the phylogeny and diversity of forestry fungi is focused on all kind of fungi in forests, especially on fungal resources, diversity, molecular phylogeny and systematics. Both reviews and research articles are welcome; papers that address the economically important groups (e.g., pathogenetic and edible forestry fungi) are especially appreciated.

The tropical montane cloud forest is the most diverse and threatened vegetation type in Mexico. In the last decade, the number of described Ascomycetes species has notably increased, reaching more than 1300 species. This study describes six new species based on their molecular and morphological characteristics. Our results suggest that Mexico has the highest number of described species in the Neotropics. However, many other Mexican lineages still need to be described. Full article

Gibellula (Cordycipitaceae, Hypocreales) is frequently observed growing on spiders, but little is known about their host range. One of the greatest challenges in describing these interactions is identifying the host, since the fungus often rapidly consumes the parasitised spiders and destroys important diagnostic taxonomic traits. Additionally, the global diversity of Gibellula remains unclear, as does the natural history and phylogenetic relationships of most of the species. Herein, we performed an extensive investigation on the species of Gibellula, reconstructed the most complete molecular phylogeny of the genus in the context of Cordycipitaceae, and performed a systematic review in order to provide the foundations towards a better understanding of the genus. Therefore, we have performed an integrative study to investigate the life history of the genus and to disentangle the questionable number of valid species proposed over time. We provided novel molecular data for published species that had not been sequenced before, such as G. mirabilis and G. mainsii, and evaluated all the original and modern morphological descriptions. In addition, we presented its global known distribution and compiled all available molecular data. We suggested a set of terms and morphological traits that should be considered in future descriptions of the genus and that a total of 31 species should be considered as accepted. Full article

The Auriculariaceae accounts for most of the species in the Auriculariales, and all species in the family are wood-decaying fungi with gelatinous, crustaceous, or woody basidiomes. Many new taxa were published recently, but the taxonomy and phylogeny of the corticioid species in the Auriculariaceae are far from resolved. We undertook a comprehensive taxonomic and phylogenetic study of the family with emphasis on corticioid specimens collected from East and Southeast Asia. Phylogenetic analyses on concatenated ITS and 28S rDNA sequences of representative taxa of the Auriculariaceae and the genera Eichleriella and Heteroradulum were carried out that resolved five new lineages. Heterocorticium gen. nov. is established for two species with resupinate coriaceous basidiomes with smooth, pigmented hymenophores. Five new species, H. bambusicola (generic type), H. latisporum, Eichleriella alpina, E. bambusicola, and Heteroradulum maolanense, are described and illustrated. In addition, Heterochaete delicata, H. discolor, and H. sinensis are transferred to Eichleriella, whereas H. roseola is regarded as a synonym of Kneiffia discolor (= H. discolor). Eichleriella aculeobasidiata is treated as a synonym of Heterochaete sinensis (= E. sinensis). Heterochaete mussooriensis is transferred to Heteroradulum with Heteroradulum semis as a heterotypic synonym. The present study contributes to the understanding of species diversity, taxonomy, and phylogeny of corticioid fungi in Asia. Full article

Peniophora is an old corticioid genus, from which two small satellite genera, Dendrophora and Duportella, were derived based on morphological differences. Molecular systematic studies showed that they belong to Peniophoraceae, Russulales, but the inter- and intra-generic phylogenetic relationships are still unclear. Moreover, the species diversity of this group in subtropical and tropical Asia has not been sufficiently investigated and studied. In this study, we carried out an intensive taxonomic and phylogenetic study on Peniophora sensu lato based on analyses of concatenated ITS1-5.8S-ITS2 (ITS, Internal Transcribed Spacer) and 28S (D1–D2 domains of nuc 28S rDNA) sequence data of all available species worldwide. In the phylogenetic trees, species of Peniophora s. l. (sensu lato) including types of Peniophora s.s. (sensu stricto), Dendrophora and Duportella were interspersed within a strongly supported clade. It means that the morphological delimitations of the three genera are not reliable, and they should be regarded as a large genus. As a result, eight species of Duportella were transferred to Peniophora, although five of them have not been sequenced. Four new distinct lineages, corresponding to Peniophora cremicolor, P. major, P. shenghuae and P. vietnamensis spp. nov., were recovered in the trees. Peniophora taiwanensis is treated as a later synonym of P. malaiensis based on morphological and molecular evidence. Duportella renispora is excluded from Peniophoraceae, because BLAST results of the ITS and 28S sequences of the holotype showed that it is closely related to Amylostereum. Descriptions and illustrations are provided for the four new species, and an identification key is given for all 25 species of Peniophora in China. Our results indicated that the species diversity of the corticioid fungi in Asia is rich and deserves further study. Full article

The lyophylloid agarics are a group of ecologically highly diversified macrofungi, some of which are very popular edible mushrooms. However, we know little about lyophylloid species diversity in China. In this study, we described four new species from China: Lyophyllum atrofuscum, L. subalpinarum, L. subdecastes, and Ossicaulis sichuanensis. We conducted molecular phylogenetic analyses of Lyophyllaceae based on the nuclear ribosomal RNA gene (nLSU) and the internal transcribed spacer regions (ITS). Phylogenetic analyses by the maximum likelihood method and Bayesian inference showed that the four new species are unique monophyletic species. A key to the species of Lyophyllum from China and a key to Ossicaulis worldwide were given. Full article

Phellodon is a genus of ectomycorrhizal fungi with important ecological roles and exploitable biological activities. In this study, four new species of Phellodon, P. caesius, P. henanensis, P. concentricus and P. subgriseofuscus, are described from China based on morphological characters and molecular evidence. The phylogenetic analyses of Phellodon were carried out based on the ITS + nLSU gene regions and the combined sequence dataset of ITS + nLSU + nSSU + RPB1 + RPB2 gene regions. Phellodon caesius is characterized by its dark bluish-grey, dark grey to black grey pileus, ash grey to dark bluish-grey spines, and the presence of both simple septa and clamp connections on generative hyphae of stipe. Phellodon concentricus is characterized by its zonate pileal surface, dark grey context in pileus, and spongy basidiomata. Phellodon henanensis is characterized by its ash grey, light vinaceous grey to light brown pileal surface, thin context in pileus, and the presence of both simple septa and clamp connections on generative hyphae of spines. Phellodon subgriseofuscus is characterized by its fuscous to black pileal surface, white to light brown spines, and vinaceous grey context. Illustrated descriptions and the ecological habits of the novel species are provided. Full article

This paper aims to understand the species diversity, taxonomy, and phylogeny of Cystostereaceae (Agaricales), which is based primarily on material from East and Southeast Asia. Cystostereaceae is a small, understudied family of saprobes of woody plants with a worldwide distribution. Phylogenetic analyses of the LSU and ITS sequences revealed four distinct clades in the Cystostereaceae, representing the genera Crustomyces, Cystostereum, Effusomyces gen. nov., and Parvodontia. In addition, phylogenetic analyses showed that Cystidiodontia and Rigidotubus are synonyms of Crustomyces for their type of species nested within the Crustomyces clade. The new monotypic genus Effusomyces, based on specimens from Thailand, lacks any distinctive morphological features. Parvodontia, originally erected for a species from South America, is reported for the first time from Asia. The widely distributed and morphologically well-characterized Cystostereum is represented in East Asia by two new species: Cystostereum crassisporum and C. submurrayi. In addition, three new species, viz., Crustomyces albidus, Effusomyces thailandicus, and Parvodontia austrosinensis, are described and illustrated. Finally, three new combinations are proposed: Crustomyces isabellinus, C. laminiferus, and C. tephroleucus. A key to the genera and species of Cystostereaceae is provided. Our results proved that the species diversity of wood-decaying fungi in East and Southeast Asia is rich and suggested that more investigations and studies should be carried out in the future.

Lasiodiplodia (family Botryosphaeriaceae) is a widely distributed fungal genus that causes a variety of diseases in tropical and subtropical regions. During 2020–2021, a routine survey of fruit tree plants was conducted in five Egyptian Governorates, and fresh samples exhibiting dieback, decline, leaf spot and root rot symptoms were collected. Collection from eight different symptomatic leaves, twigs, branches and roots of fruit trees yielded 18 Lasiodiplodia-like isolates. The sequencing data from the internal transcribed spacer region (ITS), partial translation elongation factor 1-alpha (tef1-a) and β-tubulin (tub2) were used to infer phylogenetic relationships with known Lasiodiplodia species. Two isolates obtained from black necrotic lesions on Phoenix dactylifera leaves were identified as a putative novel species, L. newvalleyensis sp. nov., and were thus subjected to further morphological characterization. The results of isolation and molecular characterization revealed that L. theobromae (n = 9) was the most common species on Mangifera indica, Citrus reticulata, C. sinensis, Ficus carica, Prunus persica, Prunus armeniaca and Pyrus communis trees. Lasiodiplodia pseudotheobromae (n = 5) was isolated from M. indica, Prunus persica and C. sinensis. Lasiodiplodia laeliocattleyae (n = 2) was isolated from C. reticulata. Pathogenicity test results suggested that all Lasiodiplodia species were pathogenic to their hosts. The present study is considered the first to characterize and decipher the diversity of Lasiodiplodia species associated with fruit trees in Egypt, using the multi-locus ITS, tef1-a and tub2 sequence data, along with morphological and pathogenic trials. To our knowledge, this is the first report of L. newvalleyensis on Phoenix dactylifera and L. laeliocattleya on C. reticulata in Egypt and worldwide. Full article

Ganoderma species are widely distributed in the world with high diversity. Some species are considered to be pathogenic fungi while others are used as traditional medicine in Asia. In this study, we sequenced and assembled four Ganoderma complete mitogenomes, including G. subamboinense s118, G. lucidum s37, G. lingzhi s62, and G. lingzhi s74. The sizes of the four mitogenomes ranged from 50,603 to 73,416 bp. All Ganoderma specimens had a full set of core protein-coding genes (PCGs), and the rps3 gene of Ganoderma species was detected to be under positive or relaxed selection. We found that the non-conserved PCGs, which encode RNA polymerases, DNA polymerases, homing endonucleases, and unknown functional proteins, are dynamic within and between Ganoderma species. Introns were thought to be the main contributing factor in Ganoderma mitogenome size variation (p < 0.01). Frequent intron loss/gain events were detected within and between Ganoderma species. The mitogenome of G. lucidum s26 gained intron P637 in the cox3 gene compared with the other two G. lucidum mitogenomes. In addition, some rare introns in Ganoderma were detected in distinct Basidiomycetes, indicating potential gene transfer events. Comparative mitogenomic analysis revealed that gene arrangements also varied within and between Ganoderma mitogenomes. Using maximum likelihood and Bayesian inference methods with a combined mitochondrial gene dataset, phylogenetic analyses generated identical, well-supported tree topologies for 71 Agaricomycetes species. This study reveals intraspecific and interspecific variations of the Ganoderma mitogenomes, which promotes the understanding of the origin, evolution, and genetic diversity of Ganoderma species.

Two new wood-inhabiting fungi Hermanssonia fimbriata sp. nov. and Phlebia austroasiana sp. nov. in the Meruliaceae family are described and illustrated from southwestern China based on molecular and morphological evidence. The characteristics of H. fimbriata include annual, resupinate basidiomata, the absence of cystidia and cystidioles, oblong ellipsoid basidiospores of 5–6 × 2.4–3 μm, and growth on rotten gymnosperm wood in the east Himalayas. Its basidiomata change drastically upon drying, from being a light-coloured, juicy, papillose-to-wrinkled hymenophore, to a dark-coloured, corky-to-gelatinous, and more or less smooth hymenophore. The characteristics of Ph. austroasiana include annual, resupinate basidiomata, a hydnoid hymenophore, 2–3 spines per mm, the presence of tubular cystidia of 20–25 × 3–3.5 µm, oblong ellipsoid basidiospores of 4.4–5.2 × 2.1–3 μm, and growth on angiosperm wood in tropical forests in the southern Yunnan Province. The phylogenetic analyses based on the combined 2-locus dataset (ITS1-5.8S-ITS2 (ITS) + nuclear large subunit RNA (nLSU)) confirm the placement of two new species, respectively, in Hermanssonia and Phlebia s. lato. Phylogenetically, the closely-related species to these two new species are discussed. Full article

During a survey of hypoxylaceous fungi in Medog county (Tibet Autonomous Region, China), three new species, including Hypoxylon damuense, Hypoxylon medogense, and Hypoxylon zangii, were described and illustrated based on morphological and multi-gene phylogenetic analyses. Hypoxylon damuense is characterized by its yellow-brown stromatal granules, light-brown to brown ascospores, and frequently indehiscent perispore. Hypoxylon medogense is morphologically and phylogenetically related to H. erythrostroma but differs in having larger ascospores with straight spore-length germ slit and conspicuously coil-like perispore ornamentation. Hypoxylon zangii shows morphological similarities to H. texense but differs in having Amber (47), Fulvous (43) and Sienna (8) KOH-extractable pigments and larger ascospores with straight spore-length germ slit. The multi-gene phylogenetic analyses inferred from the datasets of ITS-RPB2-LSU-TUB2 supported the three new taxa as separate lineages within Hypoxylon. A key to all known Hypoxylon species from China and related species worldwide is provided. Full article

Although species of Absidia are known to be ubiquitous in soil, animal dung, and insect and plant debris, the species diversity of the genus and their ecological habitats have not been sufficiently investigated. In this study, we describe five new species of Absidia from forest and grassland soils in southwestern China, with support provided by phylogenetic, morphological, and physiological evidence. The species diversity and ecological habitat of Absidia are summarized. Currently, 22 species are recorded in China, which mainly occur in soil, especially in tropical and subtropical forests and mountains. An updated key to the species of Absidia in China is also provided herein. This is the first overview of the Absidia ecological habitat. Full article

Two new wood-inhabiting fungi, Sidera salmonea sp. Nov. and S. tibetica sp. Nov. in the order Hymenochaetales from southwest China, are described and illustrated based on molecular and morphological evidence. They were found on gymnosperm wood that is rotten and charred. The characteristics of S. salmonea include annual, resupinate basidioma, salmon pores with distinctly white margins, angular pores (7–9 per mm), a dimitic hyphal system, and lunate basidiospores that are 3–3.5 × 0.9–1.1 μm. The characteristics of S. tibetica include annual, resupinate basidioma with a white to cream fresh pore surface that becomes cream to honey-yellow and shiny when dry, round pores (7–8 per mm), a dimitic hyphal system, and lunate basidiospores that measure 2.9–3.1 × 1–1.1 μm. A phylogenetic analysis based on the combined 2-locus dataset (5.8S + nuclear large subunit RNA (nLSU)) shows that the two species are members of the genus Sidera, and they are morphologically compared with related species, respectively. This paper provides a key to the identification of 16 accepted species of Sidera that are found throughout the world. Full article
