[in Russian with English abstract: ] As a result of the revision of the MSK-L collection, lichens of 11 localities of maritime and continental Antarctic, diverse in species composition, were revealed. The collection includes three ecological groups of lichens. The material for this article was the lichen samples stored in the MSK-L collection in the amount of about 600 herbarium packages collected during 1 CAE, 5 SAE, 63 Russian Antarctic expeditions and 2, 3, 4, 6, 11, 12 Belarusian Antarctic expeditions. 82 species of lichens from 54 genera were identified. Most of the identified species were found in maritime Antarctic. 16 species of lichens were common to maritime and continental Antarctic. Most of the species are classified as bipolar lichens. Thin layer chromatography of genus Lepraria lichens was carried out. It has been shown that usnic acid and zeorin are present only in the Antarctic endemic L. straminea.
