摘要：
Five new Cortinarius species in subgenus Telamonia are described from western North America: Cortinarius alboambitus Niskanen, Liimat. & Ammirati sp. nov., Cortinarius brunneovernus Niskanen, Liimat. & Ammirati sp. nov., Cortinarius fructuodorus Niskanen, Liimat. & Ammirati sp. nov., Cortinarius nauseosouraceus Niskanen, Liimat. & Ammirati sp. nov., and Cortinarius politus Niskanen, Liimat. & Ammirati sp. nov. Phylogenetic relationships of the species were inferred by analysis of ITS and rpb2. The placement of C. brunneovernus in sect. Brunnei, C. fructuodotus in sect. Telamonia, and C. nauseosouraceus in sect. Cinnabarini/Uracei/Colymbadini is strongly supported. Cortinarius alboambitus grouped with species in the clade Furvolaesi with a support of 0.83 posterior probabilities, and C. politus with the species in sect. Boulderenses with 0.67 posterior probabilities. The descriptions of these species are presented and a comparison with similar species is provided.
