[In Ukrainian with English abstract: ] History of the study of lichens in the Ukrainian Polissya is analysed. First information about lichens in the given region is dated from 1830, but only after 1925 studies of this region have become regular. A.M. Oxner, V.R. Maslova, S.D. Zelenko have made the most valuable contribution to the study of lichens in the Ukrainian Polissya. Some data on lichens from single localities of Ukrainian Polissya are in the papers of M.F. Makarevich, O.G. Roms, L.I. Frantsevich, O.B. Blum, S.Ya. Kondratyuk, I.L. Navrotskaya, O.Ye. Khodosovtsev. At present 338 species of lichens and 12 species of lichenicolous fungi are found in Ukrainian Polissya. Southern administrative regions of Volyns'ka, Rivnen and Zhytomyr oblasts (within Polissya), and northern regions of L'viv, Ternopil and Khmel'nyts'k oblasts found to be in urgent need of special study as poorly the investigated badly or not investigated regions in respect to lichens.
