Abstract
Wood‐inhabiting fungi can decompose lignin, cellulose, and hemicellulose and play an integral role in the material cycle of forest ecosystems. In this study, we proposed a new species Scopuloides fimbriata , which was collected from Yunnan Province, southwest China. This new species is characterized by a smooth, white to buff hymenial surface and cylindrical, colorless, thin‐walled basidiospores measuring 4.5–6.3 × 2–3 µm. The phylogenetic analysis was performed with Maximum Likelihood, Bayesian Inference, and Maximum Parsimony methods based on ITS + nLSU nuclear RNA gene regions. Phylogenetic analysis showed that S. fimbriata formed a monophyletic lineage within the family Meruliaceae and it is closely related to the type species of Scopuloides , S. hydnoides .
