Trechisporales, typified by Trechispora and equivalent to Hydnodontales, is a recently introduced order within Agaricomycetes. This order only comprises one family Hydnodontaceae and 16 independent genera, but the relationships among these genera are not fully clarified. Here, via a wider sampling especially from Asia Pacific, careful morphological...

Wood-inhabiting fungi have important economic values as well as playing a major ecological role in forest ecosystem cycles. The Dabie Mountains, at the junction of Henan, Hubei, and Anhui Provinces, Central China, provide an ideal climate and favorable niches for the speciation and diversification of various forms of life including fungi. We studied the species diversity and community phylogenetics of wood-inhabiting basidiomycetous fungi that revealed 175 wood-inhabiting basidiomycetous species, of which 20 represented unidentified species, based on morphological and phylogenetic analyses of 575 specimens collected from ten sampling sites. These species belonged to two classes, 11 orders, 42 families, and 106 genera of Basidiomycota, and included 12 edible species, 28 medicinal species, four poisonous species, and seven forest pathogens. Four types of fungal distribution pattern at the genus level were recognized for 65 genera, while another 41 genera could not be placed in any known distribution pattern. The five sampling sites in the eastern part of the Dabie Mountains had significantly higher species diversity and phylogenetic diversity of wood-inhabiting basidiomycetous fungi than those in the western part, and thus deserve priority in terms of conservation. The community of wood-inhabiting basidiomycetous fungi in the Dabie Mountains is generally affected by a combination of habitat filtering and competitive exclusion. This study provides a basis on which to build actions for the comprehensive recognition, utilization, and conservation of wood-inhabiting basidiomycetous fungi in the region.

... In Zong et al. (2021), newly describing Trechispora daweishanensis and T. xantha, the first phylogeny did not recover the monophyly of Trechispora with these two species, while the second one simply including taxa only from Trechispora as the ingroup clustered the two species with T. yunnanensis and separated them from additional species of Trechispora. As first noted by Chikowski et al. (2020) and then confirmed by Liu et al. (2022a), the ITS and nLSU sequences from specimens of T. yunnanensis (Xu et al. 2019) actually represent different species from Trechisporales and Hymenochaetales, respectively, and thus the phylogenetic position of T. yunnanensis itself is doubtful. Liu et al. (2022c) recognized the incorrect generic placements of T. daweishanensis and T. xantha by Zong et al. (2021), and transferred these two species to Brevicellicium. ...
... However, the phylogeny supporting these transfers was also on the basis of a simple phylogeny (Liu et al. 2022c: Fig. 1), in which these two species also clustered together with species of Brevicellicium but occupied a separated position. By sampling the most comprehensive range of taxa in Trechisporales available to date, the phylogeny in Liu et al. (2022a) clarified these two species placing them outside of both Trechispora and Brevicellicium, and in a new genus, Allotrechispora. ...
... Besides the uncertain phylogenetic position, the poroid hymenophoral surface also makes H. poroides distinguished from other species of Hyphodermella (Zhao et al. 2017). Although macrofungal species producing various hymenophoral configurations commonly can be placed in the same genus (Wang et al. 2021b;Liu et al. 2022a), in this case it is obvious, not as stated in the Abstract by the authors: "Both morphological and molecular evidences confirmed the placement of the new species in Hyphodermella. " (Zhao et al. 2017). ...
The genus is a special and crucial taxonomic rank compared with others above the species level, because a species has to be placed in a certain genus instead of any other higher ranks. With more and more new species being described, the placements of their generic position are sometimes incorrect due to the simple phylogenies resulting from inappropriate sampling. Here, we focus on the taxonomy of a small wood-inhabiting fungal genus Hyphodermella . With the most comprehensive sampling to date, the phylogenetic position of Hyphodermella within Phanerochaetaceae is rearranged by employing the same ITS and nLSU regions as in previous studies and also the ITS, nLSU, rpb1 , rpb2 and tef1α regions. Three species are excluded from Hyphodermella : H. poroides is placed in a newly introduced monotypic genus Pseudohyphodermella , while H. aurantiaca and H. zixishanensis are transferred to Roseograndinia . Hyphodermella suiae is described as a new species from South China and Vietnam. Keys to eight species in Hyphodermella and five in Roseograndinia are provided. Beyond solving the taxonomic issue of Hyphodermella itself, the current study also aims to suggest that all fungal taxonomists especially beginners should keep in mind to sample as many comprehensive taxa as possible in phylogenetic analyses.

The genus Trechispora accommodate species with corticioid, clavarioid, and polyporoid basidiomata, smooth to verrucose, angular basidiospores, monomitic or dimitic hyphal systems with clamp-connections, and ampullaceous septa. During a study of clavarioid fungi of Kerala, seven Trechispora species with clavarioid basidiomata were collected and studied. Morphological and molecular analyses revealed one species, T. cystidiata , characterized by cystidia, to be new to science. In addition, a new combination ( T. angulispora ) and a nomen novum ( T. corneri ) are also proposed. Descriptions of all the species collected and studied from Kerala, along with their phylogenetic placement in the order Trechisporales is presented. A taxonomic key to the clavarioid species of Trechisporales from India is also provided.
Four new wood-inhabiting fungi, Trechispora albofarinosa, T. bisterigmata, T. pileata and T. wenshanensisspp. nov., are proposed based on a combination of morphological features and molecular evidence. Trechispora albofarinosa is characterized by the farinose basidiomata with flocculence hymenial surface, a monomitic hyphal system with clamped generative hyphae, and ellipsoid, warted basidiospores. Trechispora bisterigmata is characterized by the membranous basidiomata with odontioid hymenial surface, rhizomorphic sterile margin, barrelled basidia and subglobose to broad ellipsoid, smooth basidiospores. Trechispora pileata is characterized by the laterally contracted base, solitary or imbricate basidiomata, fan shaped pileus, radially striate-covered surface with appressed scales, odontioid hymenophore surface, and subglobose to broad ellipsoid, thin-walled, smooth basidiospores. Trechispora wenshanensis is characterized by a cottony basidiomata with a smooth hymenial surface, and ellipsoid, thin-walled, warted basidiospores. Sequences of ITS and LSU marker of the studied samples were generated, and phylogenetic analyses were performed with the maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenetic tree inferred from the ITS+nLSU sequences highlighted that four new species were grouped into the genus Trechispora.
China has a huge area of diverse landscapes and is believed to conceive incredibly high fungal diversity. To systematically and promptly report Chinese fungal species, we initiate the series of Catalogue of fungi in China here. In the first paper of this series, we focus on plant-inhabiting fungi. A total of 33 new taxa are described all over China. These taxa include two new genera, viz., and N. yoshinagae. The morphological characteristics and phylogenetic evidence are used to support the establishment of these new taxa and the accuracy of their taxonomic placements. We hope that the series of Catalogue of fungi in China will contribute to Chinese fungal diversity and promote the significance of recording new fungal taxa from China. ARTICLE HISTORY

Two new species of Trechispora indigenous to southern China, T. laxa and T. tongdaoensis , are described and illustrated, and the first record of T. khokpasiensis in China is reported. Molecular phylogenetic analyses of the concatenated nuclear rDNA ITS1–5.8S–ITS2 and nuclear large subunit sequences supported the inclusion of the three species within the Trechispora clade, together with species formerly classified in Scytinopogon . The new species are similar in micromorphology to species of Trechispora (as traditionally circumscribed) but are distinguished by having coralloid basidiomata. A key to the known coralloid Trechispora species in China is provided.
In the era of molecular phylogeny as dominant evidence in fungal taxonomy, the taxonomic framework of fungi adopted from morphological characteristics has been largely updated. Compared with other fungal groups, macrofungi underwent fewer updates at the order and higher level. In this study, the taxonomic placement of a poorly known macro-basidiomycetous genus Xenasmatella is studied. Phylogenetic and molecular clock analyses inferred from a seven-locus dataset support that the genus represents an order rank lineage. Accordingly, a monotypic order Xenasmatellales and a monotypic family Xenasmatellaceae are newly introduced for Xenasmatella within Agaricomycetes. The species diversity and relationships of Xenasmatella are further clarified with the aid of the phylogenetic analysis inferred from a four-locus dataset. In association with morphological characteristics, a new species Xenasmatella hjortstamii is described. Moreover, the distribution of Xenasmatella ailaoshanensis, X. gossypina, and X. wuliangshanensis previously known only from type localities in Yunnan Province, China are expanded. In addition, two unnamed single-specimen lineages of Xenasmatella from Victoria State, Australia and Sichuan, China are revealed, likely representing two potential new species of this genus. In summary, the current study updates the taxonomic framework of Agaricomycetes and provides a crucial supplement for comprehensively understanding the evolutionary history of this fungal class.
During the rainy season in Thailand, specimens of coral fungi were collected from community forests in Chiang Mai and Kalasin Provinces. The species presented here, Trechispora khokpasiensis, T. saluangensis, and T. sanpapaoensis are characterized by coralloid basidiomata and described as new taxa in Hydnodontaceae (Trechisporales) based on analyses of their morphological characters and phylogenetic relationships from the nuclear ribosomal large subunit (LSU) as well as the internal transcribed spacer regions’ (ITS) sequence data. Morphological descriptions and illustrations, including color photographs, line drawings and phylogenetic trees, are presented. Comparisons with similar species are also provided.
