Cortinarius bovinus and morphologically similar conifer-associated species were studied using material mainly from northern Europe. To stabilize the nomenclature, relevant types were examined. Phylogenetic relationships and species limits were investigated with rDNA ITS and nuclear rpb2 sequences as well as morphological data. We recognize seven species: C. bovinus (neotypified) and six new species, C. anisochrous, C. bovinaster, C. bovinatus, C. fuscobovinus, C. fuscobovinaster and C. oulankaënsis. Their taxonomy, ecology, distribution and relationships are discussed, and a key to species is provided. Based on our phylogeny and morphological data the species were placed in section Bovini.
