A new Gerronema species with striking colours from China

Abstract

Gerronema indigoticum sp. nov., distinctive for its blue to blue-green basidiomata, is described as a new taxon from subtropical China. Photographs of basidiomata, morphological features and relevant illustrations of this species are presented. Morphological characters compared with related Gerronema species and phylogenetic analyses conducted based on the internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences with Maximum Likelihood (ML) and Bayesian Analysis (BA) tree show that the new taxon can be distinguished from phenotypically similar and phylogenetically related species.
