Gymnopilus minisporus sp. nov., a new species and a new record of the European species G. hybridus from northeast China

Abstract

During our field work in northeast China, two species of Gymnopilus, Gymnopilus minisporus sp. nov. and Gymnopilus hybridus, were identified and described based on morphological characteristics and phylogenetic analyses. The main distinguishing characteristic of G. minisporus is the conspicuously small basidiospores. The phylogenetic tree based on internal transcribed spacers of rDNA sequences using Bayesian and Maximum Likelihood methods showed that G. minisporus has an independent monophyletic lineage, and G. hybridus from China and Sweden grouped in a monophyletic branch.
