[in Polish with English abstract: ] A new locality of a rare fruticose lichen species Evernia divaricata in the western part of Poland was found in the vicinity of two cities: Gubin and Twardogóra. Single specimens of this epiphytic lichen, grew on larch and birch. The thalli were healthy and well developed. Evernia divaricata is under strict legal protection and considered an endangered species in Poland (the CR category in the „Red List of Polish Lichens”). In the last dozen or so years, over a dozen new localities of E. divaricata have been found in the country, which usually grew in the company of other lichens very sensitive to air pollution, e.g. from the genus Usnea. These taxa are a testimony to the increasing process of recolonization. Key words: distribution of lichens, rare and endangered lichens, epiphytes, recolonization, Góry Izerskie Mts, Sudety Mts.
