The focus of this paper is the North American species of Cortinarius in subg. Leprocybe . Eighteen species, including twelve new ones, and two tentative (aff.) species, are delimited based on morphological and molecular data (DNA ITS-LSU sequences). Existing type specimens of species in subg. Leprocybe were also studied, and neo- or epitypes designated for C. cotoneus , C. melanotus , C. phrygianus and C. venetus to stabilize the nomenclature. In addition, to improve the infrasubgeneric classification of Leprocybe three new sections are proposed: sect. Fuscotomentosi , sect. Melanoti and sect. Squamiveneti . This study adds substantial information to the knowledge of subg. Leprocybe in North America against a background of European species. To date only two species, C. phrygianus and C. squamivenetus have been reported from both continents.
