[in Russian with English abstract: ] The revision of the herbarium material of lichens in the MSK, LE, and KW collections revealed that the genus Parmelia in the Republic of Belarus is represented by the following species: P. barrenoae, P. ernstiae, P. omphalodes, P. saxatilis, P. serrana, P. submontana, and P. sulcata. The most common of these species in Belarus is P. sulcata, which is known from 6 regions and 61 administrative districts of the Republic and is found on 20 species of trees and shrubs, as well as on other substrates. Lichen P. fraudans is excluded from the flora of Belarus. It was noted that lichens P. barrenoae, P. ernstiae, P. omphalodes, P. saxatilis and P. submontana are rare species. The article indicates the location of the collections; the lichens are confined to biotopes and substrates. A key for identifying lichens of the genus Parmelia in Belarus has been compiled. The resulting material will be used in the preparation of the next volume of the «Flora of Belarus. Lichens». Keywords: lichens, morphology, herbarium, occurrence, chemical composition, Belarus.
