Agaricus section Arvenses: three new species in highland subtropical Southwest China.
Fungal Biol. 2015 Mar; 119(2-3):79-94.FB

Abstract

Agaricus is a genus of saprobic basidiomycetes with more than 400 species recognized worldwide, with about 50 species known in China. Our objective was to investigate three new species of section Arvenses in highland subtropical Southwest China. Agaricus guizhouensis is a new species characterized by a white pileus with yellowish squamules, small ellipsoid spores and cheilocystidia with yellowish-brown pigments; another new species, Agaricus longistipes is recognized by its slender stipe, and its elongate-ellipsoid basidiospores; the third new one, Agaricus megalocarpus is remarkable by its large size and its pileus surface covered with fine brown squamules. It is firstly reported for Guizhou Province that Agaricus abruptibulbus, Agaricus flocculosipes, and Agaricus subrufescens are illustrated. Two probable new species require further studying. A phylogenetic analyses of rDNA-ITS sequence data belonging to section Arvenses showed that the section Arvenses is monophyletic and can be subdivided in five branches, the branch of A. subrufescens and four clades (A-D). The eight species from highland subtropical Southwest China were distributed in all five branches, indicating that this highland is at the climatic crossroads. The white pileus trait and the potential interest are discussed. These data suggest a potential species richness that remains to be discovered.
