Wood-decaying fungi play crucial roles as decomposers in forest ecosystems. In this study, two new corticioid fungi, Rhizochaete fissurata and R. grandinosa spp. nov., are proposed based on a combination of morphological features and molecular evidence. Rhizochaete fissurata is characterized by resupinate basidiomata with a cracking hymenial surface, a monomitic hyphal system with simple-septa generative hyphae, presence of subfusiform to conical cystidia encrusted at the apex or coarse on the upper half, and ellipsoid basidiospores. Rhizochaete grandinosa differs in its resupinate basidiomata with a smooth hymenial surface, presence of two types of cystidia, and ellipsoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were employed, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods on two datasets (ITS+nLSU and ITS). Both dataset analyses showed that two new species clustered into the genus Rhizochaete, in which, based on the ITS+nLSU dataset, R. fissurata was sister to R. belizensis, and R. grandinosa grouped with R. radicata; the phylogram inferred from ITS sequences inside Rhizochaete indicated that R. fissurata formed a monophyletic lineage with a lower support; R. grandinosa grouped closely with R. radicata. In addition, an identification key to all Rhizochaete species worldwide is provided.

Wood-inhabiting fungi play crucial roles as decomposers in forest ecosystems and, in this study, two new wood-inhabiting corticioid fungi, Hyphoderma puerense and H. tenuissimumspp. nov., are proposed, based on a combination of morphological features and molecular evidence. Hyphoderma puerense is characterised by effused basidiomata with smooth to floccose hymenial surface, a monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. Hyphoderma tenuissimum is characterised by resupinate basidiomata with tuberculate to minutely-grandinioid hymenial surface, septate cystidia and cylindrical to allantoid basidiospores. 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. These analyses showed that the two new species clustered into Hyphoderma, in which H. puerense grouped with H. moniliforme and H. tenuissimum formed a singleton lineage. In addition, an identification key to Chinese Hyphoderma is provided.

Two new corticioid fungal species, Phanerochaete pruinosa and P. rhizomorpha spp. nov. are proposed based on a combination of morphological features and molecular evidence. Phanerochaete pruinosa is characterized by the resupinate basidiomata with the pruinose hymenial surface, a monomitic hyphal system with simple-septate generative hyphae and subcylindrical basidiospores measuring as 3.5–6.7 × 1.5–2.7 µm. Phanerochaete rhizomorpha is characterized by having a smooth hymenophore covered by orange hymenial surface, the presence of rhizomorphs, subulate cystidia, and narrower ellipsoid to ellipsoid basidiospores. Sequences of ITS+nLSU nrRNA gene regions of the studied specimens were generated and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that two new species clustered into genus Phanerochaete, in which P. pruinosa was sister to P. yunnanensis with high supports (100% BS, 100% BT, 1.00 BPP); morphologically differing by a pale orange to greyish orange and densely cracked hymenial surface. Another species P. rhizomorpha was closely grouped with P. citrinosanguinea with lower supports; morphologically having yellow to reddish yellow hymenial surface, and smaller cystidia measuring as 31–48 × 2.3–4.8 µm.

Two new species, Xylodon bambusinus and X. xinpingensis, are proposed based on morphological and molecular evidences. Both species share the annual growth habit, resupinate basidiomata and monomitic hyphal system with clamped, colorless generative hyphae, smooth, thin-walled basidiospores, but X. bambusinus is characterized by the smooth to tuberculate hymenial surface, presence of capitate and fusiform cystidia, broad ellipsoid basidiospores, while X. xinpingensis by the reticulate hymenophore with cream hymenial surface, and subglobose basidiospores (4.5–6 × 3.5–5 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on molecular data of ITS and ITS+nLSU sequences showed that X. bambusinus was sister to X. subclavatus, while X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus. The nLSU dataset revealed that X. bambusinus grouped with X. asperus and X. brevisetus with lower supports, and that X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus and then with X. rimosissimus without supports. Both morphological and molecular evidences confirmed the placement of two new species in Xylodon. Description and figures from the new species and a key to the known species of Xylodon from China are presented.

A new wood-inhabiting fungus, Phlebia nigrodontea, is proposed based on a combination of morphological features and molecular evidence. The species is characterized by a grandinioid hymenophore with vinaceous brown to black colour, a monomitic hyphal system with clamped generative hyphae and ellipsoid, colourless, thin-walled, smooth basidiospores (3.9–4.9 × 2.3–3.1 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses carried out using maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on the molecular data of ITS+nLSU sequences showed that P. nigrodontea nested within the phlebioid clade. A further investigation of more representative taxa from Phlebia, based on ITS+nLSU sequences, demonstrated that the species P. nigrodontea formed a monophyletic lineage with strong support (100% BS, 100% BT, 1.00 BPP) and closely grouped with P. chrysocreas.

A new mycoparasitic fungal species, Tuberculina photiniae sp. nov., is proposed based on morphological and molecular evidence. The species is characterized by its depressed hemispherical pale lilac to greyish purple sporodochia breaking through leaf surfaces, septated conidiophores with vinaceous lower parts and colourless upper parts, and the presence of colourless globose, subglobose or scarcely wide-ellipsoid conidia. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analysis based on molecular data of ITS sequences showed that Tuberculina photiniae belongs to the Tuberculina-Helicobasidium clade and is closely related to H. longisporum and H. mompa. Further investigation was carried out for representative taxa in the Tuberculina-Helicobasidium group based on ITS+nLSU sequences in which the results demonstrated that the new species formed a monophyletic lineage and grouped with H. longisporum and H. mompa. Both morphological and molecular evidence confirmed the placement of the new species in the Tuberculina-Helicobasidium clade.

Three new wood-inhabiting fungi, Hyphoderma crystallinum, H. membranaceum, and H. microporoides spp. nov., are proposed based on a combination of morphological features and molecular evidence. Hyphoderma crystallinum is characterized by the resupinate basidiomata with smooth hymenial surface scattering scattered nubby crystals, a monomitic hyphal system with clamped generative hyphae, and numerous encrusted cystidia present. Hyphoderma membranaceum is characterized by the resupinate basidiomata with tuberculate hymenial surface, presence of the moniliform cystidia, and ellipsoid to cylindrical basidiospores. Hyphoderma microporoides is characterized by the resupinate, cottony basidiomata distributing the scattered pinholes visible using hand lens on the hymenial surface, presence of halocystidia, and cylindrical to allantoid basidiospores. Sequences of ITS+nLSU rRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that three new species clustered into Hyphoderma, in which H. crystallinum was sister to H. variolosum, H. membranaceum was retrieved as a sister species of H. sinense, and H. microporoides was closely grouped with H. nemorale. In addition to new species, map to show global distribution of Hyphoderma species treated in the phylogenetic tree and an identification key to Chinese Hyphoderma are provided.

Molecular Characters

A new poroid wood-inhabiting fungal species, Atraporiella yunnanensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by cream pore surface when dry, which is easy to separate from substrate and very rapidly stained dark brown to black when bruised; hyphal system monomitic with generative hyphae hyaline to pale brown, thin-walled, unbranched, interwoven; slightly allantoid basidiospores, 2.2–3 × 0.8–1.5 µm. The internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analysis based on molecular data of ITS+nLSU sequences showed that Atraporiella yunnanensis belonged to the residual polyporoid clade, formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and was closely related to A. neotropica, and then grouped with other related genera: Antrodiella, Pouzaroporia, Steccherinum and Xanthoporus. Both morphological and molecular characters confirmed the placement of the new species in Atraporiella.
