A conspicuous and probably the best-known member of the genus. It is often called “hippo skin” thanks to its thick and rough thallus. Apart from the characteristic appearance, D. scruposus is a relatively variable lichen. Further diagnostic features are the 8-spored asci and the content of lecanoric acid (C+ red), sometimes also diploschistesic acid.
The lichen is common on acidic to slightly basic siliceous rocks. It prefers sun-exposed outcrops from lowlands to mountains. It is a cosmopolitan species, widespread and common in Europe as well as in the Czech Republic.taxonomic classification:
