摘要

A new polypore species, Fuscoporia subferrea, is described from southern China based on morphological characters and phylogenetic analysis. The new species is characterized by annual, resupinate basidiocarp, hyaline, thin-walled, smooth, cylindrical basidiospores measured as 4.2-5.8 x 2.2-2.6 mu m. It resembles F. ferrea, but differs by smaller pores (7-10/mm vs. 5-7/mm) and narrower basidiospores (4.2-6.2 x 2.0-2.6 mu m vs. 4.2-5.2 x 2.8-3.5 mu m). Phylogenetic analyses inferred from the ITS and nLSU sequences indicate that the new species forms a distinct lineage with strong support and is closely related to F. ferrea.
