Protoparmelia badia (Hoffm.) Hafellner

Protoparmelia badia is a relatively common crustose lichen, usually growing on hard siliceous rocks with high quartz content. It is usually found on, at least partly, exposed rock outcrops and boulder screes. It also grows on partially anthropogenic substrates, such as rocky walls, rock piles in pastures, border stones, gravestones, etc. The species is more abundant in the Czech border mountains, but is not rare elsewhere either (e.g., the Brdy highlands, the Žďárské vrchy hills). Locally, it can also be found at lower elevations, e.g., on acidic extrusive rocks in northern Bohemia or hard rock outcrops in the valleys of larger rivers in central Bohemia and southern Moravia. Where locally abundant, it may exceptionally also colonize trees.
