Abstract

Pluteus ochroviridans sp. nov. is described based on collections made in Spain and California (USA). This species is characterized by a strongly hygrophanous, brown, gray-brown to yellow-brown pileus that develops green tones, and by its terrestrial habitat in Mediterranean ecosystems. Phylogenetic analyses of ITS and TEF1-α sequences separate this species from closely related taxa: P. californicus, P. olivaceus, and P. phaeocyanopus. We obtained sequences from the type collections of these three closely related taxa, thus establishing DNA reference data for the modern taxonomic concepts of these species. A full description, illustrations, and phylogenetic analysis results of the new species are provided.
