Príspevok k poznaniu lišajníkov okolia Moravskej Třebovej

Several lichens collected in the vicinity of the town Moravská Třebová by M. Michálek in 1973 and determined by I. Pišút are listed. The occurrence of acidophilous lichens (especially of Lecanora conizaeoides) and scarcity of mederately sensitive species confirm the deterioration of epiphytic lichen flora there even in the early seventies.
