Abstract

A new wood-rotting fungal species, Punctulariopsis yunnanensis, is proposed based on a combination of morphology and molecular data. The species is characterized by the resupinate basidiomata with a pinkish buff salmon hymenial surface, a monomitic system, generative hyphae with clamp connections, and subhymenial generative hyphae thick-walled, and the presence of dendrohyphidia, and broadly ellipsoid basidiospores measuring 7.8–12.8 × 6–9.8 µm. Phylogenetic analyses of the combined ITS and nLSU nrDNA gene regions demonstrated that P. yunnanensis formed an independent lineage and was sister to P. subglobispora with strong statistical support. A full description, illustrations and phylogenetic analysis results of the new species are provided.
