The genus Campylopus in Russia is revisited based on molecular phylogenetic data, which included also European accessions originated from vicinities of the loci classici of several species. Eight species are proved to occur in Russia, among which C. schimperi is widespread in montane areas throughout the country, while other species are known from few localities in Kamchatka (5 species), southern part of Russian Far East (3 species), Caucasus (3 species) and Kaliningrad Province (1-3 species). Nuclear ITS allowed a reasonable delimitation of C. schimperi and C. subulatus; previously known differences in their morphology, ecology and distribution are confirmed. Molecular phylogenetic reconstruction, based on combined plastid trnS-trnF, mitochondrial Nad5 and nuclear ITS suggests that the genus Campylopus harbours at least three well morphologically and phylogenetically justified lineages, which could be considered as separate genera to prevent assigning Pilopogon to synonymy of Campylopus.
