Abstract
Hypocrealean fungi are a well-documented group of fungi, with a wide range of ecological roles that include saprobic, parasitic, and endophytic forms, capable of thriving in diverse environments, both terrestrial and marine. Members in this group are abundant and widely distributed in marine environments around the world. However, the species diversity and distribution of this fungal group in Chinese seas is rarely reported. This study introduces five new species, namely Fusarium flavoides M.M. Wang & W. Li, Gliomastix fasciculata M.M. Wang & W. Li, Marquandomyces ulvae M.M. Wang & W. Li, Stephanonectria arenicola M.M. Wang & W. Li, and Verruciconidia oligospora M.M. Wang & W. Li, based on morphological characteristics and LSU-ITS-tef1-rpb2 phylogenetics. These new species were discovered from marine algae (Ulva spinulosa) and sediments (mud and sand). A detailed comparison of these new species and their close relatives is also presented.
1. Introduction
The order Hypocreales Lindau was established in 1897, and recently this fungal group is now considered to be one of the most substantial orders of the class Sordariomycetes [1], comprising approximately 320 genera in 15 families [2]. Historically, the classification of this order has undergone numerous revisions, with a modified characterization of the Hypocreales being proposed in 1970 [3]. Subsequent to this, a considerable number of species were assigned to this order, and an updated taxonomic system for this group of fungi was conducted. Morphologically, members of this order, also known as hypocrealean fungi, are frequently characterized by colorful sexual structures such as white, light orange, and black, and the typically asexual structures that were summarized as Acremonium-like, Cylindrocarpon-like, Fusarium-like, Paecilomyces-like, and so on [4,5,6,7].
Hypocrealean fungi exhibit a broad spectrum of host/habitat and ecological functions, encompassing saprophytes, parasites, and endophytes in soil and plants in terrestrial habitats [7,8]. Furthermore, these fungi have been identified in a wide range of marine environments around the world. For instance, studies using culturable methods have revealed that species in genera Acremonium Link and Fusarium Link have a worldwide distribution in sediments, corals, sponges, sea fans, and seaweeds [9,10,11,12,13]. However, the distribution of culturable hypocrealean fungi in Chinese seas has been sporadically reported, with the exception of Acremonium egyptiacum (J.F.H. Beyma) W. Gams, Emericellopsis maritima Beliakova, and Neocosmospora solani (Mart.) L. Lombard & Crous from marine carbs in Taiwan [14], Fusarium aseptatum Meng Li & L. Cai from mangrove sediment in Guangdong [15], and several species including A. egyptiacum and Purpureocillium lilacinum (Thom) Luangsa-ard, Houbraken, Hywel-Jones & Samson from marine algae in Shandong [16]. Considering the high relative abundances of these fungi revealed by unculturable methods in the Yellow Sea of China [17] and their ecological roles (endophyte, parasite, pathogen, and saprotroph) identified by FungalTraits [18], we believe that the marine environments in China should be inhabited by diverse hypocrealean fungi that probably perform important ecological functions.
During the past decade, our group has conducted a long-term survey of fungal diversity in Chinese seas (e.g., [19,20,21,22]) and accumulated a number of hypocrealean strains from various marine samples such as algae, seawater, and sediment. The present study introduced five new species from marine algae and sediments in the intertidal zones, based on their morphology and culture characteristics. The taxonomic placements of these new species were confirmed by multi-locus phylogenetic analyses of LSU, ITS, tef1, and rpb2. Comparisons were made between the new species and their close relatives.
2. Materials and Methods
2.1. Sample Collection and Fungal Isolation
Algae samples were collected from intertidal zones in the Guangdong province (Shenzhen), while sediment samples (2–20 cm depth) were obtained from the Liaoning province (Dalian and Huludao) and the Shandong province (Qingdao, Weihai and Yantai). The collection of samples was conducted in accordance with the protocol described in Wang et al. [22]. The isolation of fungal strains from the algae and sediment samples was undertaken employing the protocol outlined by Wang et al. [22]. In summary, samples of algae and sediment were collected and stored in sterile bags in a 4 °C freezer and transferred to the laboratory promptly. The algae samples were then cut into 0.5 × (0.2–0.5) cm segments, surface-sterilised, and placed onto isolation media (tissue-isolation method). Segments were homogenised, diluted to a series of concentrations (10−1, 10−2, 10−3, and 10−4), and spread onto isolation media (dilution plate method). Sediment samples were directly dispersed onto isolated medium plates (direct isolation method), and suspended, cultivated by shaking, diluted (10−1, 10−2, 10−3, and 10−4), and plated onto isolation media (dilution plate method) [22]. Fifty types of media that are consistent with the formula of Wang et al. [22], including Martin medium (MM), 1/10 potato dextrose agar (1/10 PDA), 1/5 malt extract agar (1/5MEA), corn meal agar (CMA), and yeast extract peptone glucose agar (YPG), were used as isolation media in this study. Fungal isolates were picked up with a sterilised needle and transferred onto potato dextrose agar (PDA) plates when individual colonies were observed. All isolates examined in this study were deposited in Wei Li’s personal culture collection (WL). Type specimens of new species were deposited in the Fungarium of the Institute of Microbiology (HMAS; https://nmdc.cn/fungarium/, accessed on 15 January 2025), with the ex-type living cultures in the China General Microbiological Culture Collection Center (CGMCC; https://www.cgmcc.net/, accessed on 15 January 2025).
2.2. Morphological Observation
Considering that fungi often exhibit distinct colony morphological characteristics on different culture media, this study employed three different culture media to obtain a more comprehensive understanding of the cultural characteristics of the studied isolates. The isolates studied were incubated in the dark on PDA and oatmeal agar (OA) at 25 °C in the dark for seven days. Seven days later, culture characteristics including colony morphology, pigmentation, and odour were observed. Colours were assessed according to the colour charts of Kornerup and Wanscher [23]. Micromorphological characteristics were examined and photo-documented using water as a mounting medium under an Olympus BX53 microscope with differential interference contrast (DIC) optics [22]. For each species, 30 conidiophores, 30 conidiogenous cells, and 50 conidia were mounted and measured randomly, respectively [22].
2.3. DNA Extraction, PCR Amplification and Sequencing
Genomic DNA was extracted from fungal mycelia grown on PDA after 7 days, using a modified CTAB protocol as described in Guo et al. [24]. Briefly, the process of fungal DNA extraction involved the grinding of fresh mycelia with CTAB buffer [24] and quartz sand, followed by incubation at 60 °C for 30 min. Subsequently, 500 μL of a solution of phenol–chloroform (1:1) was added, mixed thoroughly, and subjected to centrifugation (11,900× g, 15 min). The aqueous phase was transferred, mixed with chloroform–isoamyl alcohol (24:1) and centrifuged again. The DNA was precipitated using 50 µL of 5M KOAc and 400 µL of isopropanol, mixed gently, centrifuged (9200× g, 2 min), washed twice with 70% ethanol, air-dried, and finally resuspended in 100 µL of TE buffer (10 mM Tris-HCl, 1 mM EDTA).
Four loci, including partial large subunit ribosomal RNA gene (LSU), 5.8S nuclear ribosomal RNA gene with the two flanking internal transcribed spacer (ITS) regions, partial translation elongation factor gene (tef1) and partial DNA-directed RNA polymerase II second largest subunit gene (rpb2), were amplified with the primer pairs ITS5 (5′-GGAAGTAAAAGTCGTAACAAGG-3′)/ITS4 (5′-TCCTCCGCTTATTGATATGC-3′) [25], LR0R (5′-ACCCGCTGAACTTAAGC-3′)/LR5 (5′-TCCTGAGGGAAACTTCG-3′) [26,27], EF-983F (5′-GCYCCYGGHCAYCGTGAYTTYAT-3′)/EF2218R (5′-ATGACACCRACRGCRACRGTYTG-3′) [28] and RPB2-5F2 (5′-GGGGWGAYCAGAAGAAGGC-3′)/RPB2-7cR (5′-CCCATRGCTTGYTTRCCCAT-3′) [29,30], respectively. The PCR amplifications were performed in a total volume of 30 μL containing 15 μL of 2 × Rapid Taq Plus Master Mix (Dye Plus) (Vazyme, Nanjing, China), 1 μL of each primer (0.1 μM), 1 μL of genomic DNA (1–10 ng), and 12 μL of ddH2O. The PCR amplifications of LSU, ITS, and tef1 were set as follows: an initial denaturation at 95 °C for 5 min, followed by 35 cycles of denaturation at 95 °C for 1 min, annealing at 48 °C (LSU), 52 °C (ITS), and 56 °C (tef1), respectively, for 1 min, and extension at 72 °C for 1 min, and a final extension step at 72 °C for 10 min. The PCR amplification for rpb2 was set as described by Wang et al. [31]. PCR products for four loci were purified and sequenced in both directions using an ABI DNA analyzer by SinoGenoMax company (Beijing, China). Consensus sequences were obtained using SeqMan of the Lasergene software package v. 14.1 (DNAstar, Madison, WI, USA).
2.4. Evolutionary Lineage Modeling
The sequences of the hypocrealean strains examined in this study and the reference strains are listed in Table 1. For each locus, sequences were aligned using ClustalX 2.1 [32], and the alignments were manually adjusted where necessary. The best-fitting nucleotide-substitution modes according to the Akaike Information Criterion (AIC) were selected using mrmodeltest2 [33]. Alignments derived from this study were deposited in TreeBASE (submission ID 31992), and taxonomic novelties were deposited in Fungal Names (https://nmdc.cn/fungalnames/, accessed on 15 January 2025).
Phylogenetic analyses of the combined dataset were performed using Bayesian inference (BI) and maximum-likelihood (ML) methods. The BI analyses were conducted using MrBayes v. 3.2.1 following the protocol of Wang et al. [31], with optimization of each locus treated as a partition in combined analyses, based on the Markov Chain Monte Carlo (MCMC) approach [34]. All characters were equally weighted, and gaps were treated as missing data. The stationarity of the analyses was determined by examining the standard deviation of split frequencies (<0.01) and –ln likelihood plots in AWTY [35]. The ML analyses were conducted using PhyML v. 3.0 [36], with 1000 bootstrap replicates. The general time-reversible model was applied with an invariable gamma-distribution rate variation (GTR+I+G).
3. Results
3.1. Phylogenetic Analyses
Analyses of the hypocrealean fungal phylogeny were conducted by using a combined LSU (875 bp), ITS (634 bp), tef1 (849 bp) and rpb2 (908 bp) dataset. For the BI analysis, the GTR+I+G model was selected for the LSU, ITS and rpb2 loci, while the GTR+G model was used for the tef1 locus. The phylogeny showed that our five new species were clustered into five genera in three families (Bionectriaceae Samuels & Rossman, Clavicipitaceae (Lindau) Earle, and Nectriaceae Tul. & C. Tul.), namely Fusarium flavoides, Gliomastix fasciculata, Marquandomyces ulvae, Stephanonectria arenicola, and Verruciconidia oligospora (Figure 1). In order to provide a more accurate illustration of the genetic relationships between the five new species and other species within the same genus, phylogenetic analyses were conducted for each genus based on multi-locus datasets (Supplementary Figure S1).

Notes: In this study, a new Fusarium species, namely F. flavoides from intertidal sediment, was introduced. Phylogenetically, this species was closely related to F. flocciferum Corda and F. iranicum Torbati, Arzanlou & Sand.-Den., but differs by 71 bp and 81 bp in the LSU-ITS-tef1-rpb2 dataset, respectively (Figure 1). Morphologically, the above species could be distinguished in the septation, shape and size of macroconidia (2–3-septate, falciform, with a pointed to blunt apical cell and a foot-shaped basal cell, 20–36.5 × 2.5–5.7 μm in F. flavoides vs. 3–5-septate, falcate, with tapering apical cells and distinctly pedicellate basal cells, 16–60 × 3–4 μm in F. flocciferum, and 0–5-septate, falcate, 15.5−20 × 3–4.5 μm in F. iranicum) [37,38,39,40]. These species differ in locations and hosts/habitats: F. flavoides was discovered from intertidal sediment in China, while F. flocciferum and F. iranicum was mostly from soil, plants, and other fungi in Germany, Iran, Netherlands, and other countries [8,41,42]. The new species is similar to F. thapsinum Klittich, J.F. Leslie, P.E. Nelson & Marasas in the production of yellowish pigment, but differs in the absence of microconidia (present in F. thapsinum) and septation and size of macroconidia (3–8-septate, 24–64 × 3–4 μm in F. thapsinum) [43]. Moreover, F. flavoides is far from F. thapsinum in the LSU-ITS-tef1-rpb2 phylogeny (Figure 1).

Cai & Crous [7]. In this study, the eighth species was introduced, namely V. oligospora. Phylogenetically, V. oligospora showed close relationship with V. persicina (Nicot) L.W. Hou, L. Cai & Crous and V. verruculosa (Figure 1), but differed by 61 bp and 99 bp in the LSU-ITS-tef1-rpb2 dataset, respectively. Morphologically, V. oligospora could be recognized in the shape and size of conidia (ellipsoid to globose, 3.3–5.7 × 2.5–4.5 μm in V. oligospora, vs. ellipsoid, ovoid, 4.2–6.2 × 2.4–3 μm in V. persicina, and ellipsoid, 4.5–6.2 × 2.5–3.5 μm in V. verruculosa) [7]. Additionally, the aforementioned species exhibit variations in their localities and hosts/habitats. For instance, V. oligospora from intertidal sediment in China, while V. persicina was discovered from coastal sand under Ammophila arenaria in France and V. verruculosa from agricultural soil in the Netherlands [7].
4. Discussion
The five new species described in this study were found to be phylogenetically well-located in five genera in three families in the order Hypocreales, with high supported values (BI = 0.97–1 and BS = 100; Figure 1). These include Gliomastix Guég., Stephanonectria and Verruciconidia in Bionectriaceae, Marquandomyces in Clavicipitaceae, and Fusarium Link in Nectriaceae, as determined by the LSU-ITS-tef1-rpb2 dataset (Figure 1). Morphologically, these species exhibited typical characteristics of Acremonium Link, yet differed from their closely related species in terms of conidiophores and shape and size of conidia, respectively. For example, all the known Stephanonectria species form sporodochial conidiophores [49,50,51] in contrast to the newly introduced species S. arenicola forms aerial conidiophores. Verruciconidia oligospora sp. nov. differs from its sister species in the size of conidia (3.3–5.7 × 2.5–4.5 μm in V. oligospora, vs. 4.2–6.2 × 2.4–3 μm in V. persicina and 4.5–6.2 × 2.5–3.5 μm in V. verruculosa) [7].
The hypocrealean fungi perform a variety of pivotal ecological functions within their respective environments, a fact that is exemplified by the five genera mentioned in this study. Members of the Fusarium (approximately 400 species) [52] are renowned pathogens of a wide range of plants and animals, and are frequently isolated from terrestrial and aquatic environments as documented in the FungalTraits database [18]. Species of Gliomastix (approximately 20 species) [52] are frequently documented as saprotrophic fungi [18] and are commonly found in soil, plants or air [7]. The genus Marquandomyces includes seven known species that have been extensively reported to play multiple crucial functions in agriculture and environmental remediation, for instance, as effective biocontrol agent against nematodes, notably reducing root galling in tomato and increasing the heat weights of lettuce [48]. The genus Stephanonectria was formerly considered to be saprotrophic fungi associated with litter, plants and soil [18]. The genus Verruciconidia has been found to be associated with air, plants and soil on a global scale [7]. The preponderance of evidence indicated that this group of fungi exhibits a wide geographical distribution and a robust capacity for environmental adaptation.
The broad ecological adaptability of hypocrealean fungi is attributable to their metabolic versatility, which concomitantly positions them as pivotal candidates for biotechnological innovation. The cross-sectoral utility of these fungi is evident in their capacity to fulfil specialised enzymatic and biochemical functions. A case in point is the mycoprotein synthesised by F. venenatum Nirenberg in the context of food manufacturing [53]. This mycoprotein is characterised by its high protein and cellulose content, and it has been commercialized as a sustainable meat alternative under the brand name Quorn [53]. In the field of chemical engineering, cutinase, a fungal enzyme produced by F. oxysporum Schltdl., has been shown to possess the capacity for polyethylene terephthalate modification [54]. Similarly, laccase-like enzymes derived from G. murorum (Corda) S. Hughes have demonstrated the ability to oxidise a wide range of organic compounds [55]. In the field of agriculture, Beauveria bassiana (Bals.-Criv.) Vuill. and Lecanicillium lecanii (Zimm.) Zare & W. Gams are effective entomopathogens that are capable of significantly reducing the survival and reproduction of insect pests like Aphis gossypii Glover through the mechanisms of direct infection and the production of toxic metabolites [56]. In the field of biomedicine, chlorinated orsellinic aldehydes derived from A. sclerotigenum (Moreau & R. Moreau ex Valenta) W. Gams have been shown to exhibit a high level of antifungal activity [57].
This study has expanded the corpus of knowledge concerning the ecological adaptation of the hypocrealean fungi. While seven Fusarium species have previously been reported from diverse host/habitat (mangrove algae, plants, sponges and sediments; etc.) in the marine environment with a wide geographic distribution and dominant presence [15,58,59] and G. murorum has been isolated from sediment of marine environments [60,61], members of the other three genera Marquandomyces, Stephanonectria and Verruciconidia were newly documented in marine environments. The present study lends further credence to the idea that hypocrealean fungi may be largely represented in marine environments. In the future, the study of these fungi will be pursued, including their species diversity, geographical distribution, host/substrate correlation and possible application value.
