[in Polish with English summary: ] The article describes five new localities of Evernia divaricata, a very rare epiphytic lichen species thought to be on the brink of extinction in Poland. Information is also provided on accompanying lichen species, some equally rare, protected and threatened, e.g. of the genera Bryoria and Usnea. Tree stands in the Jizera Mts were destroyed as a result of the environmentally disastrous levels of air pollution in the 20th century, which led to the extinction of the majority of epiphytic lichens and even some epilithic ones. The article records the recent appearance of numerous epiphytic species, which is evidence of accelerating recolonization and thus of the very marked improvement in air quality.
