Abstract

A new species of Lyophyllum (Basidiomycota, Agaricomycetes), Lyophyllum aurantiacum sp. nov., is introduced based on morphological characters and multi-gene phylogenetic analysis. Lyophyllum aurantiacum has large basidiomata, grayish-orange pileus, lamellae decurrent, a cylindrical stipe that slightly enlarges towards the base, unchanging in colour when injured, globose to subglobose basidiospores, abundant clamp connections in pileus context, hymenophoral trama and stipe context. Phylogenetic analyses based on internal transcribed spacer (ITS) and nuclear large subunit (nrLSU) sequences confirmed this species as a novel taxon within Lyophyllum. This discovery updates the knowledge of edible fungi in southwestern China.
