Abstract
Based on traditional morphological and phylogenetic analyses (ITS, LSU, tef-1α and β-tub ) of psathyrelloid specimens collected from China, four new species are here described: Heteropsathyrella macrocystidia , Psathyrella amygdalinospora , P. piluliformoides , and P. truncatisporoides . H. macrocystidia forms a distinct lineage and groups together with Cystoagaricus , Kauffmania , and Typhrasa in the /Psathyrella s.l. clade, based on the Maximum Likelihood and Bayesian analyses. Thus, the monospecific genus Heteropsathyrella gen. nov. is introduced for the single species. Detailed descriptions, colour photos, and illustrations are presented in this paper.
