Abstract:
Four new species of the genus Phaeocollybia (Hymenogastraceae, Agaricales) from Yunnan Province, southwestern China, namely, P. ochrilata, P. conicogregaria, P. profundirhizoidea, and P. purpureorosea, are described and illustrated based on morphological data and multilocus phylogenetic analyses from DNA sequences of the internal transcribed spacer (ITS) and the second largest subunit of RNA polymerase II (RPB2). Our phylogenetic analyses revealed that the four new species belong to P. subgen. Phaeocollybia. Color photos of fresh basidiomata, line drawings of microscopic features, and their comparisons with allied taxa are presented.
