Postia stellifera sp. nov., a stipitate and terrestrial polypore from Malaysia

Postia stellifera sp. nov. from Malaysia is described. This fungus is characterized by the distinctly stipitate basidiomata, terrestrial habit, and verrucose chlamydospores both in the context and in culture. Its macromorphology resembles that of Albatrellus, but phylogenetic analysis based on LSU places it within a clade comprising Postia, Amylocystis, and Jahnoporus where all species have a white and fleshy to soft corky context and monomitic hyphal system with clamped generative hyphae. Most sequences showing high homology with P. stellifera represent brown rot polypores.
