Leptogium saturninum (Dicks.) Nyl.

One of the largest genus members with a light, tomentose lower-side of the thallus and black isidia on the upper-side. The species grows on mossy bark of old deciduous trees and is very sensitive to air pollution. In central Europe, the lichen is currently rare. It used to be reported from more localities in the past (Černohorský et al. 1956) but nowadays it is one of the rarest lichens in the country. The only recent record comes from the glacial cirque of the Plešné jezero lake in the Šumava Mts (Palice, unpublished). In the 1990s, the species was found also in the Bavarian part of the Šumava Mountains, on Mt Roklan, very close to the Czech borders (Palice, unpublished), therefore its occurrence in the neighbouring areas, such as the boggy area near Modrava, cannot be ruled out.
