Summary
Urbanavichus G. P. & Urbanavichene I. N. 2018. Lichens and lichenicolous fungi of terricolous habitats in alpine-nival belts of Mount Elbrus (North Caucasus, Russia). – Phyton (Horn, Austria) 58 (2): 117–122, with 4 figures.*


Mount Elbrus, the highest peak of the Caucasus Mountains, is relatively rich in arctic-alpine lichens, but no study has been specifically devoted to its terricolous lichens. An investigation of the terricolous lichens and their lichenicolous fungi on the southern slope of Mt. Elbrus at elevations above 3100 m in the summer of 2017 yielded 92 taxa (80 lichenized and 12 lichenicolous fungi). Three species, Micarea viridiatra Coppins, Leptosphaerulina peltigerae (Fuckel) Riedl and Sphaerellothecium leratianum Gardiennet & Cl. Roux are new to Russia, and Acarospora rhizobola (Nyl.) Alstrup , Calogaya bryochrysion (Poelt) Vondrák, Lecanora concolor Ramond, Lepraria borealis Lohtander & Tønsberg, Leptosphaerulina peltigerae, Micarea viridiatra, Polyblastia helvetica Th. Fr., Rhagadostoma brevisporum (Nav.-Ros. & Hladun) Nav.-Ros., Sphaerellothecium leratianum, S. stereocaulorum Zhurb. & Triebel, and Tetramelas geophilus (Flörke ex Sommerf.) Norman are new to the Caucasus.
