In this present study, five new wood-inhabiting fungal taxa, Botryobasidium gossypirubiginosum, Botryobasidium incanum, Botryobasidium yunnanense, Coltricia zixishanensis, and Coltriciella yunnanensis are proposed. Botryobasidium gossypirubiginosum is distinguished by its slightly rubiginous hymenial surface, monomitic hyphal system, which branches at right angles, and subglobose, smooth basidiospores (14–17.5 × 13–15.5 µm); B. incanum is characterized by its white to incanus basidiomata having a hypochnoid hymenial surface, and ellipsoid, smooth basidiospores (6.5–8.5 × 3.5–5 µm); B. yunnanense is characterized by its buff to slightly yellowish hymenial surface, monomitic hyphal system, and broadly ellipsoid to globose, smooth, thick-walled basidiospores (11.5–14.5 × 9.5–10.5 µm); Coltricia zixishanensis differs in its rust brown pileal surface, and ellipsoid, thick-walled basidiospores (5–6.5 × 4–4.5 µm). Coltriciella yunnanensis is distinguished by its tiny pilei, short stipe, and navicular, verrucose basidiospores (10.5–12.5 × 6–7 µm). Sequences of ITS and nLSU genes were used for phylogenetic analyses using the maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenetic results inferred from ITS sequences revealed that B. gossypirubiginosum was closely related to B. robustius; the species B. incanum was grouped with B. vagum; B. yunnanense was related to B. indicum. The species C. zixishanensis was grouped with C. confluens and C. perennis. ITS sequences revealed that C. zixishanensis was grouped into the genus Coltriciella, in which it was grouped with Co. globosa and Co. pseudodependens.

Four new wood-inhabiting fungi were found in Southwestern China within the genera Phanerochaete, Phlebiopsis, Asterostroma, and Vararia of the families Phanerochaetaceae and Peniophoraceae, belonging to the orders Polyporales and Russulales individually. Combined with their morphological characteristics and molecular biological evidence, the present study describes them as new fungal taxa. Asterostroma yunnanense is characterized by the resupinate, membranaceous to pellicular basidiomata with a cream to salmon-buff hymenial surface, hyphal system dimitic bearing simple-septa, thin- to thick-walled, yellowish brown asterosetae with acute tips, and thin-walled, echinulate, amyloid, globose basidiospores. Phanerochaete tongbiguanensis is characterized by the resupinate basidiomata with a white to cream hymenial surface, a monomitic hyphal system with simple-septa generative hyphae, the presence of subclavate cystidia covered with a lot of crystals, and oblong ellipsoid basidiospores (6–9 × 3–4.5 µm). Phlebiopsis fissurata is characterized by the membranaceous, tuberculate basidiomata with a buff to slightly brown hymenial surface, a monomitic hyphal system with simple-septa, conical cystidia, and broadly ellipsoid. Vararia yingjiangensis is characterized by a corky basidiomata with a pinkish buff to cinnamon-buff hymenial surface, cracking, yellowish dichohyphae with slightly curved tips, subulate gloeocystidia, and thick-walled, ellipsoid basidiospores (6.5–11.5 × 5–7 µm). The phylogenetic analyses of ITS + nLSU revealed that the two new species were nested into the genera Phanerochaete and Phlebiopsis within the family Phanerochaetaceae (Polyporales), in which Phanerochaete tongbiguanensis was sister to P. daliensis; Phlebiopsis fissurata was grouped with P. lamprocystidiata. Two new species were clustered into the genera Asterostroma and Vararia within the family Peniophoraceae (Russulales), in which Asterostroma yunnanense was sister to A. cervicolor; Vararia yingjiangensis formed a single branch.

Two new corticioid fungi in the family Phanerochaetaceae, Phanerochaete shenghuaii and Rhizochaete variegata, are described and illustrated from Southwest China based on morphological characteristics and molecular data. Phanerochaete shenghuaii is characterized by annual, effused, inseparable basidiocarps from substrate, ivory white to cream hymenial surface when juvenile, buff to yellowish brown with age, buff in KOH, a monomitic hyphal system, smooth cystidia, and ellipsoid basidiospores measuring 4.8–6 × 2.5–3.8 µm. Rhizochaete variegata is characterized by annual, effused, easily separable basidiocarps from substrate, buff-yellow to clay-pink fresh hymenial surface becoming cream to buff upon drying, violet in KOH, a monomitic hyphal system, encrusted cystidia, and ellipsoid basidiospores measuring 3–4 × 2.2–3 µm. The phylogenetic analyses based on ITS + nLSU rDNA sequences confirm the placement of the two new species, respectively, in the Phanerochaete clade and the Rhizochaete clade of Phanerochaetaceae. Phylogenetically related and morphologically similar species to these two new species are discussed.
... New DNA sequencing techniques have revolutionized the researches of fungal taxonomy and diversity, in which about 150 thousand species of fungi have been described (Hyde, 2022). Wood decaying fungi have been studied intensively in recent years (Bernicchia and Gorjoń, 2010;Dai, 2011;Cui et al., 2019;Guan et al., 2020;Wang and Zhao, 2021;Westphalen et al., 2021;Wu et al., 2021a;Wu et al., 2021b;Wu et al., 2021b;Qu et al., 2022;Wu et al., 2022a;Wu et al., 2022b), but the hydnoid species in the order Polyporales are still not well investigated in China, especially in the subtropics and tropics. In the present study, three new species, Steccherinum fissurutum, S. punctatum and S. subtropicum spp. ...
The wood-inhabiting fungi play an integral role in wood degradation and the cycle of matter in the ecological system. They are considered as the “key player” in wood decomposition, because of their ability to produce all kinds of enzymes that break down woody lignin, cellulose and hemicellulose. In the present study, three new wood-inhabiting fungal species, Steccherinum fissurutum, S. punctatum and S. subtropicum spp. nov., collected from southern China, are proposed based on a combination of morphological features and molecular evidence. Steccherinum fissurutum is characterized by the resupinate, subceraceous basidiomata with cracked hymenophore, a monomitic hyphal system with clamped generative hyphae and cylindrical basidiospores; S. punctatum is characterized by the annual, punctate basidiomata with leathery hymenophore, cylindrical, strongly encrusted cystidia and ellipsoid basidiospores (3.6–4.5 ×2.6–3.4 µm); S. subtropicum is characterized by its effuse-reflexed basidiomata, a odontioid hymenophore with pink to lilac hymenial surface and ellipsoid basidiospores measuring as (2.8–3.4 × 2.0–2.7 µm). Sequences of ITS and nLSU rRNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The ITS+nLSU analysis of the family Steccherinaceae indicated that the three new species clustered into the genus Steccherinum. Based on further analysis of ITS+nLSU dataset, the phylogenetic analysis confirmed that S. subtropicum was sister to S. enuispinum; S. fissurutum formed a monophyletic lineage; S. punctatum grouped with a clade comprised S. straminellum and S. ciliolatum.

... Wood-rotting fungi are an extensively studied group of Basidiomycota [12,13,[60][61][62][63][64][65][66] and the three taxa of Trechispora are a typical example group of wood-rotting fungi [15,[33][34][35]67]. Based on our present morphology and phylogeny focusing on Trechispora, all taxa in this genus can be separated from the three new species. ...
Trechispora are an important genus of wood-inhabiting fungi that have the ability to decompose rotten wood in the forest ecosystem. In this study, we reported three new species of Trechispora: T. murina, T. odontioidea, T. olivacea from a subtropical region of Yunnan Province, China. Species descriptions were based on a combination of morphological features and phylogenetic analyses of the ITS and LSU region of nuclear ribosomal DNA. Trechispora murina is characterized by the resupinate basidiomata, grandinioid hymenial surface with a greyish tint, monomitic hyphal system and ellipsoid, thick-walled, ornamented basidiospores; T. odontioidea has an odontioid hymenial surface with cylindrical to conical, blunt aculei and subglobose to globose, colorless, slightly thick-walled, ornamented basidiospores; T. olivacea has a farinaceous hymenial surface with olivaceous tint, basidia clavate and thick-walled, ornamented, broadly ellipsoid to globose basidiospores. Sequences of the ITS and nLSU rDNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. After a series of phylogenetic analyses, the 5.8S+nLSU dataset was constructed to test the phylogenetic relationship of Trechispora with other genera of Hydnodontaceae. The ITS dataset was used to evaluate the phylogenetic relationship of the three new species with other species of Trechispora. Using ITS phylogeny, the new species T. murina was retrieved as a sister to T. bambusicola with moderate supports; T. odontioidea formed a single lineage and then grouped with T. fimbriata and T. nivea; while T. olivacea formed a monophyletic lineage with T. farinacea, T. hondurensis, and T. mollis.
... The species diversity, taxonomy, and phylogeny of the phlebioid clade in Polyporales were intensively studied recently by many authors, and a large number of new taxa from East Asia were described (Floudas and Hibbett, 2015;Miettinen et al., 2016;Justo et al., 2017;Ma and Zhao, 2019;Chen et al., 2020Chen et al., , 2021Xu et al., 2020;Wang and Zhao, 2021;Zhao et al., 2021;Tian et al., 2022). This study furthers our knowledge of this group with the addition of seven new corticioid species in the Irpicaceae. ...
The phylogenetic analyses of the family Irpicaceae were carried out based on a complete global sampling. The dataset that included concatenated ITS1-5.8S-ITS2 and nrLSU sequences of 67 taxa of Irpicaceae from around the world was subjected to the maximum likelihood analyses and Bayesian inference. In the phylogenetic tree, species from 14 genera were distributed in nine clades, among which five genera—Irpex, Phanerochaetella, Byssomerulius, Cytidiella, and Meruliopsis, received high support values. The genus Efibula was shown to be paraphyletic and four subclades could be recognized, while Phanerochaete allantospora, Leptoporus mollis, and several species from Ceriporia and Candelabrochaete formed a large clade with relatively strong support. Based on the molecular and morphological evidence, seven new corticioid species—Candelabrochaete guangdongensis, Efibula grandinosa, E. hainanensis, E. shenghuae, E. taiwanensis, Irpex alboflavescens, and Phanerochaetella sinensis, were revealed from the materials mostly from East Asia. The monotypic genus Flavodontia, newly described from southwestern China, is regarded as a later synonym of Irpex, and the new combination I. rosea is proposed. In addition, Phanerochaetella queletii is proposed for a taxon first described from Italy and newly recorded from China; Phanerochaete jose-ferreirae from Portugal is determined to be a later synonym. Descriptions and illustrations of the new species and the newly combined taxa are presented, and morphological comparisons for the known species of Efibula and Phanerochaetella are provided.
Six field surveys were carried out in Zixishan area, Yunnan Province, China during 2016–2021, and 1407 specimens of wood-decaying fungi were collected. The paper summarizes the obtained results on the wood-decaying fungi of this area, consisting of 74 species belonging to 49 genera, 24 families and 7 orders. Polyporales is the dominant order (51.35% of the total species), and Hyphoderma, and Peniophorella are the dominant genera (Each accounted for 6.76% of the total) in this area. Their hosts and substrates were also identified and a checklist of wood-decaying fungi is provided. The taxa were identified by morphology and molecular evidence. The sequences of the Internal Transcribed Spacer (ITS) gene region of the studied specimens were generated and the phylogenetic analyses were performed. Five new species were earlier described in Zixishan area viz. Hyphoderma fissuratum C.L. Zhao & X. Ma (2021: 37), H. microporoides C.L. Zhao & Q.X. Guan (2021: 9), H. tenuissimum C.L. Zhao & Q.X. Guan (2021: 153), Hyphodermella zixishanensis C.L. Zhao (2021: 4), and Phanerochaete pruinosa C.L. Zhao & D.Q. Wang (2021: 8). This work aimed to provide an updated checklist of wood-decaying fungi in Zixishan area, Yunnan Province, China, as well as to enrich the knowledge of the fungal diversity in China and worldwide.
Phanerochaete is an important genus of wood-inhabiting fungi that can decompose rotten wood in forest ecosystems. In this study, we describe three new species of Phanerochaete viz. P. daliensis, P. subtropica, and P. subtuberculata from the Yunnan-Guizhou Plateau, China. A combination of morphological features and phylogenetic analyses were used to describe these species. Firstly, P. daliensis possesses a cracking basidioma, grandinioid hymenophore with white hymenial surface, monomitic hyphal system with simple septate generative hyphae, and ellipsoid to elongate to cylindrical basidiospores. In comparison, P. subtropica possesses a smooth basidioma with rhizomorphic sterile margins, monomitic hyphal system with subhymenial hyphae densely covered by crystals, and ellipsoid basidiospores. Finally, P. subtuberculata is characterized by a tuberculate basidioma with slightly olivaceous to pale brown hymenial surface, monomitic hyphal system, clavate cystidia with a tapering apex, and ellipsoid basidiospores. Sequences of the ITS and LSU rDNA markers of 12 genera related to the genus Phanerochaete within the family Phanerochaetaceae (Polyporales) were generated and phylogenetic analyses were performed using maximum likelihood, maximum parsimony, and Bayesian inference methods. The results of the phylogenetic analysis indicated that the three new species belong to the genus Phanerochaete. Further, the phylogram inferred from the ITS dataset revealed that P. subtuberculata is a sister group to P. crystallina and that P. subtropica grouped with P. daliensis.
The species diversity, taxonomy, and phylogeny of five corticioid genera of Phanerochaetaceae, namely, Hyphodermella, Roseograndinia, Phlebiopsis, Rhizochaete, and Phanerochaete, in East Asia are studied by using the morphological and molecular methods. Phylogenetic analyses were performed separately for the Donkia, Phlebiopsis, Rhizochaete, and Phanerochaete clades based on ITS1-5.8S-ITS2 and nrLSU sequence data. In total, seven new species were found, two new combinations are suggested, and a new name is proposed. In the Donkia clade, Hyphodermella sensu stricto was strongly supported with two new lineages, namely H. laevigata and H. tropica, which were recovered. Hyphodermella aurantiaca and H. zixishanensis are members of Roseograndinia, while R. jilinensis is proved to be a later synonym of H. aurantiaca. In the Phlebiopsis clade, P. cana sp. nov. was found on the bamboo from tropical Asia. In the Rhizochaete clade, four new species, R. nakasoneae, R. subradicata, R. terrestris, and R. yunnanensis were recovered based mainly on molecular analyses. In the Phanerochaete clade, P. subsanguinea nom. nov. is proposed to replace Phanerochaete rhizomorpha C.L. Zhao & D.Q. Wang, which is an invalid name because it was published after Phanerochaete rhizomorpha C.C. Chen, Sheng H. Wu & S.H. He, representing another species. Descriptions and illustrations are provided for the new species, and discussions are given for new taxa and names. Identification keys to Hyphodermella species worldwide and Rhizochaete species in China are given separately.
