Gomphus matijun, a new edible species, is described from southwestern China based on phylogenetic and morphological evidence. Phylogenetic analyses of the nrLSU and ITS datasets indicated that G. matijun is related to G. crassipes and G. ludovicianus with weak statistical support in maximum likelihood but strong statistical support in Bayesian analyses. Gomphus matijun is characterized by its gray-blue to blue or blue-purple pileus with a round or irregular outline, relatively smaller basidiospores [9-11(-13) × 6-7(-8) μm], mostly 2-spored basidia, and occurs in subtropical fagaceous forests. A key to the known species of Gomphus is provided.
