A Taxonomic Study of Candolleomyces Specimens from China Revealed Seven New Species.

Based on phylogenetic analysis, Candolleomyces (Psathyrellaceae, Agaricales) was established with Psathyrella candolleana as the type species. The basidiomes range from small to large and are typically terrestrial, lignicolous, and rarely fimicolous. We analysed the Candolleomyces species collected during five years in China, and based on morphological and molecular data (nrITS, nrLSU, and tef-1α ), we propose seven new Candolleomyces species viz. C. brevisporus , C. gyirongicus , C. lignicola , C. luridus , C. shennongdingicus , C. shennongjianus , and C. sichuanicus . Full descriptions, colour photographs, illustrations, phylogenetic analyses results, and comparisons with related Candolleomyces species of the new taxa are provided. This study enriches the species diversity of Candolleomyces in China.
