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.

Four new wood-inhabiting fungal species, Lyomyces bambusinus, L. cremeus, L. macrosporus and L. wuliangshanensis, are proposed based on a combination of morphological and molecular evidence. Lyomyces bambusinus is characterized by resupinate basidiomata with colliculose to tuberculate hymenial surface and broadly ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. Lyomyces cremeus is characterised by resupinate basidiomata with smooth, cream hymenial surface and ellipsoid, hyaline, thin-walled to slightly thick-walled basidiospores. Lyomyces macrosporus is characterized by pruinose basidiomata with reticulate hymenial surface, presence of three kinds of cystidia and larger basidiospores (6.7–8.9 × 4.4–5.4 µm). Lyomyces wuliangshanensis is characterized by coriaceous basidiomata and ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. The phylogenetic analyses based on molecular data of the internal transcribed spacer (ITS) region sequences revealed that the four new species belonged to Lyomyces. Lyomyces bambusinus grouped with L. sambuci. Lyomyces cremeus clade was sister to a clade comprised of L. microfasciculatus. Lyomyces macrosporus was sister to L. allantosporus. Lyomyces wuliangshanensis was closely related to L. mascarensis.

Wood-inhabiting fungi play a significant role in wood degradation and the cycle of matter in the ecological system. In the present study, three new wood-inhabiting fungal species, Trechispora bambusicola, Trechispora fimbriata, and Trechispora fissurata spp. nov., are nested in Trechispora, which are proposed based on a combination of morphological features and molecular evidence. Sequences of internal transcribed spacer (ITS) and large subunit (nLSU) regions of the studied samples were generated, and the phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenetic analyses inferred from ITS showed that T. bambusicola was sister to Trechispora stevensonii, T. fimbriata grouped with Trechispora nivea, and T. fissurata grouped with Trechispora echinospora. The phylogenetic tree based on ITS + nLSU sequences demonstrated that T. bambusicola formed a single lineage and then grouped with Trechispora rigida and T. stevensonii. T. fimbriata was sister to T. nivea. T. fissurata grouped with Trechispora thelephora.
