Abstract

Calypogeia fissa is a species poorly known in Russia, which description has not been published in native literature since 1936. It is reported for the first time for the mainland Leningrad Region fr om the Kurgalsky Peninsula, near the Russian-Estonian border. Previously it was collected in the Leningrad Region in Hogland Island, Gulf of Finland. These are the only known recent records of C. fissa fr om the Northwestern European Russia at its eastern lim it of distribution in Europe. The species is represented in the study area by C. fissa f. subintegrifolia, which may be easily confused in the field with the other species of Calypogeia due to its mostly entire leaves. Morphological description and photographs of C. fissa from the Leningrad Region and its habitat in the Kurgalsky Peninsula are provided. Distribution, ecology, variation and differentiation of C. fissa are discussed.
