Morphological characteristics and phylogenetic analysis reveal <i>Punctulariopsis fissurata</i> sp. nov. (Punctulariaceae, Basidiomycota) from Yunnan, China

ABSTRACT A new wood‐inhabiting fungal species, Punctulariopsis fissurata , is proposed based on morphological description and molecular verification. The species is characterised by the resupinate basidiomata with a pinkish buff salmon hymenial surface, a monomitic system with the generative hyphae bearing clamp connections and the presence of dendrohyphidia with broadly ellipsoid basidiospores measuring 13–15.5 × 8.5–11.5 µm. Phylogenetic analysis of the combined nrDNA‐ITS and LSU gene sequences verified that P. fissurata formed an independent lineage sister to P. efibulata with strong statistical support. A full description, illustrations and phylogenetic analysis results of the new species are provided.
