A section-based taxonomy of Cortinarius, covering large parts of the temperate North and South Hemispheres, is presented. Thirty-seven previously described sections are reviewed, while another forty-two sections are proposed as new or as new combinations. Twenty additional clades are recovered but not formally described. Furthermore, six new or combined species names are introduced, and one species is neotypified. The structure is supported by morphological characters and molecular evidence, based on two (nrITS and nrLSU) and four (nrITS, nrLSU, rpb1 and rpb2) loci datasets and analysed by Maximum Likelihood methods (PhyML, RAxML). Altogether 789 Cortinarius samples were included in the study.
