Rhodocybe subasyae is described from northeast China as a new species with both morphological and molecular characteristics, which is morphologically characterized by its tricholomatoid basidiomata, orange white to beige red pileus, adnexed to sinuate lamellae and long clavate branched cheilocystidia within section Rufobrunnea. The phylogenetic tree based on internal transcribed spacers of rDNA (nrITS) sequences using Bayesian methods showed that new taxon was distinguished from other species of Rhodocybe.
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 Basidiomycota. In this study, a new species of wood-rotting fungus, Sistotrema yunnanense, 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 S. yunnanense was nested within the genus Sistotrema s.l. of the family Hydnaceae, within the order Cantharellales.
