Morphological characters and molecular data reveal a new species of Fomitopsis (Polyporales) from southern China.

Fomitopsis subfeei sp. nov. is described from southern China based on morphological and molecular evidence. This fungus is characterized by perennial, effused-reflexed to pileate basidiomes, concentrically sulcate pileal surface, pinkish brown to vinaceous brown pore surface, fusoid cystidioles, small, oblong-ellipsoid basidiospores (4–5 × 1.9–2.5 μm), and occurrence on gymnosperms. Morphologically, Fomitopsis subfeei is similar to F. feei and F. incarnata , but distinct from the latter two species phylogenetically. Phylogeny based on the internal transcribed spacer regions and nuclear large subunit ribosomal RNA gene regions supported Fomitopsis subfeei as a distinctive new species in Fomitopsis .
