Strobilomyces minor (Boletaceae), a new species associated with fagaceous plants in Central China

摘要

A new species, Strobilomyces minor, associated with host plants of Fagaceae, is introduced based on morphological and molecular studies. Strobilomyces minor is characterized by its small basidiomes, light yellowish brown appressed pyramidal scales on the pileus and stipe, large hymenophoral pores, and reticulate basidiospores with large meshes. Maximum Likelihood and Bayesian analyses based on four gene markers (rpb1, rpb2, tef1 and cox3) as well as morphological characters confirmed that this new taxon belongs to Strobilomyces and it is distinct from any known species. A morphological description with line drawings and SEM images for the species is provided.
