Parmelia submontana Nádv. ex Hale – new records in Poland

Parmelia submontana is quite a rare epiphytic lichen in both Poland and central Europe. In Poland, it grows mainly in the mountains and in the northern part of the country. We found eight new localities of P. submontana, in northern and southwestern Poland. We report it here as a new species for Wigry National Park. Distribution of the species in Poland is presented on the map.
