In the current study, a new fungus species Hebeloma bingolense sp. nov. is described and illustrated based on materials collected in Bingol, Turkey. Drawings of microscopic characters, scanning microphotographs of the basidiospores, and color pictures of the basidiomes in their natural habitats are provided. Molecular analysis was also carried out to characterize the new species reliably by using DNA sequences of nuclear ribosomal internal transcribed spacers (nrITS) and nuclear large subunit of ribosomal RNA gene (nrLSU). The phylogenetic position and evolutionary relationships of H. bingolense with other species of Hebeloma are inferred by means of Maximum Likelihood (ML) and Bayesian Inferences (BI) of the concatenated dataset. The novel taxon is located within a well-supported clade formed by members of Hebeloma section Hebeloma and it is closely related to H. dunense and H. alpinicola.
