This article presents research works of lichenoflora and lichenoindications for Bryansk and Orel (Southern Non- Chernozem zone of Russia). For Bryansk and Orel have been identified 58 and 52 epiphytic lichen species respectively. 19 indicator species used for biodiagnostic the general condition of the atmosphere. Epiphytic lichen flora in the central part of the cities include from 10 to 13 species, the peripheral part - 26 to 30, the park zone - 43 species. Leading families are Parmeliaceae, Lecanoraceae, Physciaceae, Teloschistaceae. The dominant genera by number of species are Lecanora and Physcia. The number of species of epiphytes described in large cities Nechernozemie exceeds the species diversity of lichen flora for small towns of Bryansk region. The content of heavy metals in thalli of epiphytic lichen species in cities exceeding approximate permissible concentration registered for lead, copper, nickel, and zinc. Xanthoria parietina has accumulating properties with respect to lead, copper, chromium (accumulation ratio is greater than 1) in Bryansk, and in Orel accumulating properties it has in relation to chromium, titanium, vanadium, arsenic, copper. Air pollution considerably affects the formation of the lichen flora in urban territories.
