Molecular phylogeny and morphology reveal a new wood-rotting fungal species, sp. nov. from the Yunnan-Guizhou Plateau.

Wood-rotting fungi are important components of woody plant ecosystems and play an active role in the decomposition and turnover of nutrients from wood, and are among the major groups of . In this study, a new species of wood-rotting fungus, , was proposed based on morphological characteristics and molecular evidence. It is characterized by resupinate basidiomata, a monomitic hyphal system having generative hyphae with clamp connections, suburniform to urniform basidia, and short-cylindrical to oblong ellipsoid basidiospores (4.5-6.5 × 3-4 µm). Phylogenetic analyses performed using the large subunit nuc rDNA indicated that was nested within the genus of the family , within the order .
