Acarospora cervina is a frequent calciphyte in the Czech Republic growing at usually low elevations on natural limestone and diabase outcrops between 200 to 600 meters in full sun. It occurs in Asia, throughout Europe, and in north Africa as well as Greenland but has not been collected in continental North America. Acarospora cervina often covers areas up to 1 dm.
It has a thallus of usually continuous brown squamules up to 3 mm wide with large red-brown to black immersed apothecia. It has a narrow parathecium instead of an expanded parathecium up to 150 µm as in A. glaucocarpa. Acarospora cervina and A. glaucocarpa can both have squamules with white margins and occur in same habitats. But A. cervina is closely related to Acarospora badiofusca and A. irregularis. All four species have dark blue (euamyloid) hymenial gel in Lugol’s.taxonomic classification:
