title: Cortinarius subgenus Callistei in North America and Europe-type studies, diversity, and distribution of species.
abstract: Five species of Cortinarius subgenus Callistei, are recognized in Europe and North America. Cortinarius callisteus, C. infucatus, and C. neocallisteus sp. nov. have a broad distribution, extending from western North America to Europe. Cortinarius tofaceus is known from eastern North America and Europe, while C. callistei sp. is known only from one locality in Sweden. All five species are primarily associated with coniferous trees. Previously the species were included either in subgenus Leprocybe or subgenus Cortinarius, but recently they have been separated into subgenus Callistei based on molecular data. Type specimens of the names associated with this subgenus were studied and a neotype proposed for C. tofaceus and an epitype for C. infucatus Barcodes for the species are deposited in RefSeq and UNITE.
