This study aims to report three new species of Conoideocrella and Moelleriella from Yunnan Province, Southwestern China. Species of Conoideocrella and Moelleriella parasitize scale insects (Coccidae and Lecaniidae, Hemiptera) and whiteflies (Aleyrodidae, Hemiptera). Based on the phylogenetic analyses of the three-gene nrLSU, tef-1α, and rpb1, it showed one new record species (Conoideocrella tenuis) and one new species (Conoideocrella fenshuilingensis sp. nov.) in the genus Conoideocrella, and two new species, i.e., Moelleriella longzhuensis sp. nov. and Moelleriella jinuoana sp. nov. in the genus Moelleriella. The three new species were each clustered into separate clades that distinguished themselves from one another. All of them were distinguishable from their allied species based on their morphology. Morphological descriptions, illustrations, and comparisons of the allied taxa of the four species are provided in the present paper. In addition, calculations of intraspecific and interspecific genetic distances were performed for Moelleriella and Conoideocrella.
... After reexamination of the holotype (K-IMI 197065), Boonmee et al. (2011) designated an epitype (MFLU 10-0057) for T. lignicola and described both the sexual morph found on a dead piece of wood of Zizyphus mauritiana and the micronematous conidia-like structures produced from ascospores on MEA. Thaxteriellopsis was then characterised by non-ostiolate, setose, superficial, broadly spherical ascomata on a subiculum; bitunicate, cylindric-clavate, short pedicellate asci, and hyaline, fusiform, phragmoseptate ascospores and with a moorella-like asexual morph (Subramanian and Sekar 1982;Yuan et al. 2020). Currently, there are two accepted species T. lignicola and T. obliqua in Thaxteriellopsis based on the phylogenetic analysis (Yuan et al. 2020). ...

... However, Wu and Diao (2022) further showed that the assignment of Linkosia in Chaetosphaeriaceae needs additional molecular data. The species in Rhamphoriaceae were mainly collected from terrestrial habitats and rarely from freshwater habitats and are mainly distributed in Asia and Europe, possibly due to extensive sampling and thorough studies (Arzanlou et al. 2007;Réblová and Štěpánek 2018;Luo et al. 2019;Hyde et al. 2020;Yuan et al. 2020;Yang et al. 2023). Arzanlou et al. (2007) introduced Rhodoveronaea to accommodate the single asexual species R. varioseptata Arzanlou, W. Gams & Crous (type species), based on the phylogenetic analyses inferred from ITS and LSU sequences. ...
... Arzanlou et al. (2007) introduced Rhodoveronaea to accommodate the single asexual species R. varioseptata Arzanlou, W. Gams & Crous (type species), based on the phylogenetic analyses inferred from ITS and LSU sequences. The asexual morph of Rhodoveronaea is characterized by straight or flexuose conidiophores with inflated basal cells; sympodial, slightly prominent conidium-bearing denticles conidiogenous cells; ellipsoidal to obovoidal, aseptate to multiseptate, with protruding base and marginal basal frill conidia (Arzanlou et al. 2007;Luo et al. 2019;Yuan et al. 2020). Later, Réblová (2009) introduced the sexual morph of R. varioseptata which is characterized by solitary or gregarious, immersed, venter subglobose to conical, neck conical; 8-spored, unitunicate, cylindrical, broadly rounded at the apex, long-stipitate asci; and fusiform, aseptate to multiseptate, and hyaline ascospores. ...
During a microfungi investigation carried out in a terrestrial forest in Guizhou Province in China, hyphomycetes on a decaying wood log in a terrestrial habitat were collected. Morphological characteristics and phylogenetic analyses of combined ITS, LSU, SSU, tef1-α, and rpb2 sequence data revealed that the collected hyphomycetes represent two distinct new species in Rhodoveronaea. The two new species introduced in this paper are Rhodoveronaea hyalina and R. lignicola. Full descriptions, illustrations, and a phylogenetic tree to show the placement of the two new species are provided.
... Fungi play critical roles in ecosystem functions (Carris et al. 2012;Sun et al. 2019). The fungal kingdom is estimated to encompass up to 19 million species, with less than 10% have been named and classified (Chethana et al. 2020;Hyde et al. 2020;Yasanthika et al. 2022;Niskanen et al. 2023). Wijayawardene et al. (2021) suggested that around 20% of fungal taxa reproduce asexually, typified by asexual reproduction or as pleomorphic species. ...

Even so, numerous taxa remain without recent sampling and molecular data, requiring comprehensive morphological and phylogenetic investigations to ensure accurate classification within the modern classification of the Hymenochaetaceae family. ...
... For molecular phylogenetic analyses, two datasets were built using sequences of ITS and nrLSU generated in this study and from previous studies available on Gen-Bank® (e.g., Chen et al. , 2020Vlasák et al. 2020;Yuan et al. 2020) (Table 1). The first one, containing a great sampling of major clades of Hymenochaetaceae, aimed to investigate the phylogenetic relationships of collected species within Hymenochaetaceae genera using Rigidoporus corticola (Fr.) ...

However, all of them have glabrous to velutinate or scrupose pileus surface and are described as having a dimitic hyphal system throughout all basidiomata. ...
Specimens of poroid Hymenochaetaceae with uniquely strigose pileus surfaces were collected and studied morphologically and phylogenetically (using as markers ITS and nrLSU ribosomal DNA). Detailed morphological examination showed that the specimens belong to two distinct species of Fuscoporia. Fuscoporia sarcites comb. nov., which is proposed and recorded for the first time in Guatemala, Honduras, and Venezuela, and the newly described Fuscoporia dollingeri sp. nov., which was collected several times in Florida (USA). Morphological and ecological data of these species are compared to other similar species, and an identification key of Neotropical Fuscoporia is provided.
... The asexual morphology of the species in this study is consistent with the basic characteristics of the genus. Morphologically, the biological relationship between Apiospora and Arthrinium has been controversial due to their similar morphological characteristics in having basauxic conidiogenesis [57]. Although some morphological features of Arthrinium species are difficult to observe in Apiospora, such as the conidiophores having black thick septa, and it is still difficult to define the boundary between Apiospora and Arthrinium by the asexual form alone [4,58]. ...
... Although some morphological features of Arthrinium species are difficult to observe in Apiospora, such as the conidiophores having black thick septa, and it is still difficult to define the boundary between Apiospora and Arthrinium by the asexual form alone [4,58]. It has been demonstrated that ascogenous Apiospora can reproduce the mycelial asexual state on artificial media such as PDA and MEA [57,60]. Despite this cultural and molecular evidence of asexual to sexual transition, the sexual morphology of Apiospora is still rarely reported [61]. ...
Apiospora is widely distributed throughout the world, and most of its hosts are Poaceae. In this study, Arthrinium-like strains were isolated from non-Poaceae in the Hainan and Fujian provinces of China. Based on the combined DNA sequence data of the internal transcriptional spacer (ITS), partial large subunit nuclear rDNA (LSU), translation extension factor 1-α gene (TEF1-α) and β-tubulin (TUB2), the collected Apiospora specimens were compared with known species, and three new species were identified. Based on morphological and molecular phylogenetic analyses, Apiospora adinandrae sp. nov., A. bawanglingensis sp. nov. and A. machili sp. nov. are described and illustrated.

Clavulina, considered to be ectomycorrhizal (ECM) fungi depending on morphological (Tedersoo et al. 2003;Wazny 2014) and molecular evidences (Tedersoo et al. 2010;Smith et al. 2011), is widely distributed in temperate and tropical ecosystems. Currently, there are 94 recognized species of Clavulina (Wu et al. 2019;Yuan et al. 2020;de Meiras-Ottoni and Gibertoni 2023), with 25 of them being described since 2010, including 9 from Brazil (Wartchow 2012;Tibpromma et al. 2017;de Meiras-Ottoni and Gibertoni 2023), 8 from Guyana Uehling et al. 2012a, b), 3 each from Mexico (Eduardo et al. 2019;Yuan et al. 2020) and China (He et al. 2016;Wu et al. 2019), and 1 each from India (Phookamsak et al. 2019) and Cyprus (Crous et al. 2019), showing particularly diverse in the tropics. ...

Three new Clavulina species, namely C. baiyunensis, C. minor, and C. lilaceorosea, were described from specimens collected from Baiyun Mountain, Guangzhou, China, based on detailed morphological studies and phylogenetic analyses of the nucleotide sequences of three loci (ITS, LSU, and RPB2). Clavulina baiyunensis is characterized by light brown to brown basidiomata with hyaline tramal hyphae. Clavulina minor has diminutive, dull white to pale brown basidiomata with hyaline tramal hyphae. Clavulina lilaceorosea has pale brown to ochre brown basidiomata with palmate branches, and light brown walls of tramal hyphae. All three new species have abundant clamp connections. A key to the known species of Clavulina from China is provided.
... vinctus" strains was observed ( Supplementary Fig. S1) as reported previously [Setliff, 1972 (as oidia); Stalpers, 1978], but they did not produce any acanthophyses. The topology of the tree estimated for Rigidoporus in Hymenochaetales was similar to that in Wu et al. (2017) and Yuan et al. (2020). Rigidoporus ulmarius (Sowerby) Imazeki CBS 186.60 formed a clade together with nine sequences, including four sequences of R. microporus (Sw.) ...
Physisporinus, a genus in Polyporales, Basidiomycota, is a versatile fungus that lives as a wood decomposer, a potential pathogen of standing trees, and an orchid mycobiont. We previously reported that some Physisporinus species inhabiting wet wood in aquatic environments such as streams and waterfalls form synnema-like structures (SSs) bearing acanthophyses at their apices, and that they produce acanthophyses on vegetative hyphae when cultured on agar media. In this study, we investigated the acanthophysis-forming ability in Physisporinus and allied genera, and experimentally demonstrated the function of SSs. Phylogenetic analyses and observations of Meripilus, Physisporinus and Rigidoporus cultures showed that all of the strains forming acanthophyses belonged to Physisporinus, whereas strains of Meripilus and Rigidoporus did not produce acanthophyses. These findings suggest that SS/acanthophysis formation is a useful taxonomic character for members of Physisporinus. When Physisporinus strains were cultured under oxygen (O2) concentrations of 5, 10, 20 and 40%, most of those cultured under 20% O2 formed the most acanthophyses. According to these experimental data, the SSs/acanthophyses in Physisporinus were considered to have a respiratory function. Physisporinus probably acquired the SS/acanthophysis-forming ability to adapt to moist and/or aquatic habitats and to decay wet wood in which the O2 concentration is often low.
... These taxa were introduced based on multigene phylogenic analysis of LSU, ITS, rpb2 and tub2 sequence data. As more and more species were placed in the genus, the taxonomic position of those species became unstable, making it difficult to accept them as distinct lineages Yuan et al. 2020;Keirnan et al. 2021). In the phylogenetic analysis of Keirnan et al. (2021), they have only included 11 Neodidymelliopsis species with the new introduction of Neodidymelliopsis tinkyukuku. ...
... In their analysis, N. cannabis formed a distinct branch, while N. negundinis (JZB38001) clustered together with N. tillae (CBS 519.95) (100% ML and 1.00 BYPP support values). Similar taxonomic uncertainty was observed in Yuan et al. (2020), which revealed the complex classification status of species within the Neodidymelliopsis. This made it is necessary to conduct an in-depth morpho-molecular comparison in Neodidymelliopsis. ...
... The qualified and assembled sequences were uploaded to the basic local alignment search (BLAST) in the National Center for Biotechnology Information (NCBI) to confirm the generic level of obtained sequences. Reference taxa and their relevant sequences were downloaded from GenBank (Table 1) following Yuan et al. (2020). Sequences obtained in this study, together with the downloaded sequences, and then the FASTA file was converted to PHYLIP and NEXUS formats via ALTER website (http://www.sing-group.org/ALTER/) ...
... Restricted geographical distribution of Fuscoporia species has been frequently reported. For example, Fuscoporia chrysea (particularly in the neotropics) and F. palmicola have only been reported in Central America (Bondarceva et al. 1992;Baltazar and Gibertoni 2010), whereas F. atlantica, F. licnoides, and F. marquesiana have only been reported in Brazil (Pires et al. 2015;Yuan et al. 2020). Additionally, new species have been reported solely based on morphological characters, such as F. bifurcata (Baltazar et al. 2009) and F. valenzuelae (Raymundo 2021). ...
Although there is a continuous increase in available molecular data, not all sequence identities in public databases are always properly verified and managed. Here, the sequences available in GenBank for Fuscoporia (Hymenochaetales) were validated. Many morphological characters of Fuscoporia overlap among the species, emphasizing the role of molecular identification for accuracy. The identities of 658 Fuscoporia GenBank internal transcribed spacer (ITS) sequences were assessed using ITS phylogeny, revealing 109 (16.6%) misidentified and 196 (29.8%) unspecified sequences. They were validated and re-identified based on the research articles they were published in and, if unpublished, based on sequences from the type, type locality-derived sequences, or otherwise reliable sequences. To enhance the resolution of species delimitation, a phylogenetic assessment of a multi-marker dataset (ITS + nrLSU + rpb2 + tef1) was conducted. The multi-marker phylogeny resolved five of the twelve species complexes found in the ITS phylogeny and uncovered five new Fuscoporia species: F. dolichoseta, F. gilvoides, F. koreana, F. reticulata, and F. semicephala. The validated ITS sequences in this study may prevent further accumulation of misidentified sequences in public databases and contribute to a more accurate taxonomic evaluation of Fuscoporia species.
