Abstract
Phylogenetic relationships of Rozites, Cuphocybe and Rapacea were assessed using molecular phylogenetic approaches. These 3 genera are placed in Cortinariaceae and have been regarded as closely related to Cortinarius. Rozites includes more than 20 species, which are characterized by having both a membranaceous partial veil in form of a persistent annulus and a membranaecous universal veil. Cuphocye (4 species) lacks an annulus or cortina, but has pigmented veil fibrils or scales. The monotypic genus Rapacea accommodates a distinct taxon with pale, nearly smooth and thick-walled basidiospores. We analyzed 56 sequences of the internal transcribed spacer region (ITS1, ITS2 and the intervening 5.8S rRNA gene) for nine species of Rozites, three species of Cuphocybe, 28 species of Cortinarius, Rapacea mariae and Protoglossum luteum. Two species of Hebeloma were used as outgroup. Large subunit (LSU) rDNA sequences from selected taxa were also analyzed. The results clearly demonstrate that Rozites species are nested within the clade /Cortinarius, and that Rozites is polyphyletic, suggesting that membranaceous veils have evolved several times in the genus Cortinarius. Also Rapacea and Cuphocybe are nested within Cortinarius, making the latter genus paraphyletic. Based on phylogenetic studies, Rozites, Cuphocybe and Rapacea are artificial genera and do not reflect natural relationships. Also the morphological delimitation of these genera from Cortinarius is critical. Therefore we synonymize Rozites, Cuphocybe and Rapacea with Cortinarius, making 15 new combinations and providing 10 new names, which became necessary due to homonyms.
