Abstract

Three new species, Candolleomycesincanus, C.subcandolleanus and C.yanshanensis, were found and described from Yanshan Mountains in China. The identification is based on morphological observation combined with phylogenetic analysis of ITS-LSU-Tef1α-TUB2. This study enriched the species diversity of Candolleomyces in Yanshan Mountains and provided important data support for the systematic study of Candolleomyces in the future.

Keywords: Psathyrellaceae; molecular systematics; new taxon; taxonomy.

Multi-gene phylogenetic tree obtained from the Bayesian analysis. Numbers above branches are Bayesian posterior probability (pp) values, Maximum Likelihood bootstrap (MLB) and Maximum parsimony bootstrap (MP) values. Asterisks (*) denote branches with pp = 1.00, MLb = 100% and MPb = 100%. Numbers above branches represent strongly and moderately support (pp ≥ 0.95, MLb ≥ 50% and MPb ≥ 50%). The red font indicates the position of the new species.
