Abstract


The paper presents the results of the research on Usnea florida in the Polish Eastern Carpathians. Three new sites of this species have been found in the Bieszczady National Park at an altitude of 800-880 m. U. florida grows on the bark of Fagus sylvatica, Populus tremula and Betula sp. The historical sites of this species in the Western Bieszczady Mts. have not been confirmed. In Poland U. florida has also been recorded in the Białowieża Forest and Gdańskie Pomerania.
