A lichen similar to the better-known D. massiliensis (= D. stenhammari) from which it differs in the thinner grey-brown thallus and affinity to siliceous rocks. Its distribution in Europe is subatlantic-submediterranean. In optimal conditions, the species commonly occurs fertile, whereas in central Europe it is rare and only sorediate forms are found. In the Czech Republic, most of its localities are in south Bohemia, where it usually occurs on acidic siliceous outcrops in forests. Furthermore, it has been recorded in the Podyjí National Park, Beskydy Mts Křivoklát region, where even epiphytic specimens have been found on lime-trees in the locality Týřov.
