Morphological Characteristics and Phylogeny Reveal Six New Species in Subgenus () from Yanshan Mountains, North China.

Species of the genus are key components of ectomycorrhizal ecosystems worldwide, some of which are famous edible fungi. Although many new species have been described in China, their diversity in North China is still poorly known. Based on the morphology observation of specimens and molecular phylogenetic analyses, combined with the current classification frame of , six new species of subgenus are proposed from the Yanshan Mountains in northern Beijing and northern Hebei Province of China in this study: viz.

Three new species of (Agaricomycetes, Agaricales, Psathyrellaceae) from the Yanshan Mountains in China.

Three new species, , and , were found and described from Yanshan Mountains in China. The identification is based on morphological observation combined with phylogenetic analysis of ITS-LSU--. This study enriched the species diversity of in Yanshan Mountains and provided important data support for the systematic study of in the future.
