abstract = {Russula Pers. (Russulales) is an important ectomycorrhizal fungal genus in alpine and Arctic regions where it occurs with Salix, Betula, Dryas, and Polygonum, yet a complex phylogenetic analysis of the genus in these habitats is lacking. This research compared collections of Russula from the Rocky Mountain alpine (CO, MT, WY) to reference specimens from Arctic and alpine habitats, mostly in Europe, using an in-depth morphological study and a phylogenetic analysis of the nuc rDNA ITS1-5.8S-ITS2 region (ITS barcode) and the second largest subunit of the RNA polymerase II gene (rpb2). 139 Russula collections were sequenced including type material. Eight species are reported for this part of the Rocky Mountain alpine zone, and two from treeline habitats. This is the first formal report of R. cf. altaica, R. saliceticola, and R. subrubens from the Rocky Mountains and of R. purpureofusca in North America. Russula laevis is reported for the first time under this name with a voucher, and not as an environmental sample. Previous reports of R. nana and R. laccata are molecularly confirmed. Two species are reported from subalpine habitats at treeline; R. montana with conifers and R. cf. altaica with Betula. In this study R. laccata, R. subrubens, and R. laevis were collected in alpine habitats but have been reported below treeline in Europe; these species may also be present at lower elevations in North America. All species have an intercontinental distribution and have been reported in other alpine or Arctic habitats, except for one possible endemic. Two unidentified and potentially new species are discussed. A key to the alpine Russulas of North America is provided. }
