A new species of Neomensularia (Hymenochaetales, Basidiomycota) from China

Neomensularia rectiseta sp. nov. is described and illustrated from China based on morphological characters and molecular evidence. It produces perennial, pileate basidiocarps with concentrically sulcate and zonate pileal surface, a duplex context, subulate and straight hymenial setae, and yellowish basidiospores. The new species macroscopically resembles N. duplicata, which differs in having annual fruiting bodies, ventricose and hooked hymenial setae, and occurs in tropical forests. In LSU and ITS based phylogenies, the new species formed a distinct lineage in the Neomensularia clade.
