Acrocordia gemmata (Ach.) A. Massal.

A crustose lichen, forming black perithecia and white thallus. The species is linked to coarse bark of deciduous trees, but most often it is found on old oaks. In the Czech Republic, it occurs at lower and middle elevations and only rarely it comes up to mountains, for example, to the Šumava Mts, where it is present in scree forests. It is a locally common species in lower parts of the Czech Republic, especially in old, well-preserved oak forests. It has also been reported from parks, gardens and avenues. In Europe, it is a widespread, in some parts even common species.
