“…Wood-inhabiting fungi were generally found in dead tree trunks, inverted wood, and artificial wood products, which can secrete various biological enzymes degrading cellulose, hemicellulose and lignin in wood into simple inorganic substances, and they play a pivotal role in forest ecosystem and are important members of ecosystem decomposition (Dai 2011). Based on the morphological and phylogenetic method, a number of wood-inhabiting fungi were recorded in China (Wu et al 2020, Dai et al 2021, Luo & Zhao 2022, Hyphoderma is one of the important representative groups of wood-inhabiting fungi (Bernicchia & Gorjón 2010), but the species diversity of this genus is still not well known in China, especially in subtropical and tropical areas of this country , Zong et al 2021, Deng & Zhao 2022, Gu & Zhao 2022. The present will be useful to push the further research on fundamental research and applied research of fungi.…”

The genus Hyphoderma is one of the most important corticioid fungi worldwide, which causes white rot in wood and plays an important role in forest ecosystems and carbon cycle. In this study, three new wood-inhabiting fungal species, H. marginatum, H. tropicum and H. yunnanense are proposed based on a combination of the morphological and molecular evidence. Hyphoderma marginatum is characterized by the cracking, hard fragile basidiomata having smooth hymenial surface with the upwarping margin, a monomitic hyphal system with clamped generative hyphae, and cylindrical basidiospores. Hyphoderma tropicum is characterized by the resupinate basidiomata with tuberculate hymenial surface, presence of the moniliform cystidia, and ellipsoid to cylindrical basidiospores (6.5-7.5 × 3-4 µm), Hyphoderma yunnanense is characterized by the corneus basidiomata, presence of clamped septate cystidia, and ellipsoid to cylindrical basidiospores. Sequences of ITS and nLSU rRNA genes were used for phylogenetic analyses using maximum likelihood, maximum parsimony, and Bayesian inference methods. The three new species of Hyphoderma inferred from ITS sequences and form separate lineages within the genus.

“…China's special ecological system, especially in some provinces located in the tropics and subtropics, has proved to be particularly favorable to the development of this group of fungi, allowing the description of many new taxa (Cui et al 2011, Cui 2013, Li and Cui 2013, Zhao et al 2013, 2019, Chen et al 2016, Yuan and Dai 2008, Zong et al 2021), therefore it is possible that new taxa of Hyphodermella species will be found after further field studies and molecular analyses.…”

A new corticioid fungal species, Hyphodermella zixishanensis, is described based on a combination of morphological features and molecular evidence. The species is characterized by an annual growth habit, resupinate basidiomata with reddish hymenial surface, a monomitic hyphal system with generative hyphae bearing simple septa, IKI–, CB– and ellipsoid, colorless, thin‐walled, smooth basidiospores. Sequences of ITS and nLSU gene regions were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses showed that the species belongs to Hyphodermella and is placed as sister to H. aurantiaca.

“…Donk ( 1963 ) first stated that Phlebiella is an invalid genus name due to a lack of generic description when erected by Karsten ( 1890 ) and Piątek ( 2005 ) proposed that Xenasmatella should be the earliest valid name of genus for this fungal group. However, most taxonomists continued to use Phlebiella (Hjortstam and Larsson 1987 ; Boidin and Gilles 1989 , 2000 ; Telleria et al 1997 ; Larsson 2007 ; Bernicchia and Gorjón 2010 ; Huang et al 2019 ; Zong and Zhao 2021 ), while only a few publications properly named species in Xenasmatella (Duhem 2010 ; Larsson et al 2020 ; Maekawa 2021 ; Zong et al 2021 ; Liu and Yuan 2022 ).…”

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.
