The vicinity of Bramsche, Niedersachsen (Germany) was visited by the Dutch lichenologists in May, 1995. Special attention was paid to the lichens on the megalithic monuments. The flora of these ’hunebedden’ still shows some Red List taxa, like Parmelia disjuncta. Several usually epiphytic species, like Gyalideopsis anastomosans, Micarea denigrata, Placynthiella icmalea, Strangospora pinicola and Xanthoria polycarpa were found on bare granite. The epiphytic lichen flora is poor, due to the air pollution from the Ruhrgebiet.
