The lichen species Nephroma orvoi is reported as new to Russia from two localities in Murmansk Region. Description and colour illustrations of the material studied are provided. The species was previously known from Norway, Sweden, Finland, Switzerland, Canada (Alberta and British Columbia), USA (Washington), and Greenland. In Russia, it grows on rock outcrops in open habitat along the shore of a Paz River (Pasvik Nature Reserve) and in the bed of a small unnamed stream (neighborhood of Fedorova Tundra Mt.). The specimens were identified by the morphology (mostly laminal, brown, corticate soredia; faveolate, wrinkle-ridged lobes; lower side with short pseudotomentum in middle and inner part) and the identification was confirmed by lichen substances (a series of specific triterpenoids).
