Based on morphological and molecular phylogenetic studies we present two new species and one new combination in Cortinarius. Species descriptions are provided, along with discussions of phylogenetic and morphological affinities to similar taxa. All species belong to section Calochroi (incl. section Fulvi and Laeticolores s. auct.). Cortinarius osloensis and Cortinarius piceae spp. nov. are described, and Cortinarius barbaricus comb. nov. is introduced. The first taxon is a fulvoid species (i.e. contain anthraquinonoid pigments), and the two latter are calochroid (non-anthraquinonoid). Cortinarius piceae is described to cover the species most often treated as Cortinarius calochrous var. coniferarum.
