SPECIES OF THE GENUS BRYORIA (PARMELIACEAE) FROM THE NORTH CAUCASUS
The paper provides a brief survey of the genus Bryoria in the North Caucasus. An identification key for 14 Bryoria species is composed for the first time for the region. The results are based on the data of field studies (in the protected nature areas of the Russian Caucasus), revision of herbarium specimens of the Komarov Botanical Institute (LE), and analysis of literature sources. Notes on the Bryoria species morphology, anatomy, ecology and distribution are presented. Bryoria vrangiana is published as a new species to the Caucasus.
