During the study of the lichen flora of the Utrish Nature Reserve (Abrau Peninsula, Krasnodar Territory), a Mediterranean-Atlantic lichen species Bactrospora patellarioides was identified for the first time for Russia and the Caucasus based on morphological and anatomical characteristics. This species grows on the trunk of Juniperus excelsa in the sub-Mediterranean xerothermic undisturbed pistacia-juniper community on the Black Sea coast. The species was previously known from the Mediterranean regions of Europe, Western Asia, North Africa, and is also known from Macaronesia and Western North America. Detailed description, habitat characteristics, ecology, and general distribution of species are presented. Notes on the genus Bactrospora are given, and a key to the Russian species (B. brodoi, B. dryina and B. patellarioides) is provided.
