Abstract
Recent work on the taxonomic revision of Cortinarius sect. Bicolores and C. sect. Saturnini has led to the redefinition of C. cinnamoviolaceus M.M. Moser. This species, previously considered a typical Bicolores, has been phylogenetically positioned outside this section and is morphologically intermediate between Bicolores and Duracini. The numerous synonyms of C. cinnamoviolaceus identified by the analysis a better understanding of the concepts of C. dolabratus Fr. and C. imbutus Fr. and to assign these two species to sections Bicolores and Saturnini, respectively. As such, this «Canada dry» species, which resembles a Bicolores, a Duracini or a Saturnini but does not belong to any of these three sections, invites us to revise the defining criteria of these three sections.
