Type studies and fourteen new North American species of Cortinarius section Anomali reveal high continental species diversity

Abstract

Section Anomali is a species-rich group in North America belonging to Cortinarius , the most diverse genus in the Agaricales. This study is based on extensive morphological investigations and molecular methods using 191 nrDNA ITS sequence data and recovered 43 phylogenetic species from which 14 are described here as new to science. We sequenced ten type materials which belonged to eight species. The synonymy of C. caesiellus with C. albidipes and C. copakensis with C. albocyaneus is proposed here. The North American occurrence of four species ( C. albocyaneus , C. anomalus , C. caninus , and C. tabularis ), so far known only from Europe, was confirmed. Thirteen species were not formally described here due to lack of relevant information. An identification key to the known Anomali species in North America is provided.
