Abstract
Sterile crustose lichens, i. e., those species that do not form fruiting bodies on the territory of Belarus, domestic scientists started to focus only at the beginning of the 21st century, despite the fact that already in the 60–70’s in the 20th century and methods for determining lichen substances in lichens were developed.
Subjects of the study were herbarium specimens of lichenized fungi of the genus Lepraria in the amount of 68 herbarium bags from the collection of lichens MSK-L. As a result of the determination of secondary metabolites in the samples and the use of morphological features, it is established that the samples studied are represented by 9 species from the genus Lepraria: L. caesioalba, L. eburnea, L. elobata, L. finkii, L. incana, L. jackii, L., neglecta, L. rigidula и L. vouauxii. Lichen Lepraria caesioalba first time provides for the territory of the republic. The biotopes and substrate association of lichens with the genus Lepraria has been established. The qualitative composition of secondary metabolites of the studied samples is revealed. Among certain species, lichens L. incana and L. finkii are common on the territory of Belarus. The herbarium material on lichens of the genus Lepraria determined using TLC can be used in the preparation of the next volume of “Flora of lichens of Belarus”.
