Strobilomyces rubrobrunneus (Boletaceae), a new species with reddish brown scales from eastern China

Abstract

A new species, Strobilomyces rubrobrunneus, is described from eastern China based on morphological and molecular evidence. Morphologically, this species is characterized by its tiny to small basidiomes, reddish-brown and more or less erect pyramidal scales, grayish black discoloration of the pileal context when bruised, reticulate spores and a subtropical distribution in a mixed forest of Fagaceae and Pinaceae. Our phylogenetic analyses based on four gene markers (rpb1, rpb2, tef1 and cox3) support its placement in Strobilomyces and its separation from other related species of this genus. Morphological illustrations and description are provided.
