The thallus of Peltula euploca is formed by conspicuous brown squamules with bluish marginal soredia. It grows on various types of calcareous and basic silicates and extrusive rocks, often in cracks with accumulating seepage water. In prefers exposed sunny stands. It is a cosmopolitan species, associated with xerothermic localities in central Europe. The lichen is probably more common only in river valleys. In the Czech Republic, it is recently more abundant in the Middle Vltava region and the surroundings of Moravský Krumlov. Otherwise, it is rare. Its historical distribution area was summarized by Suza (1942, 1947) who listed tens of localities in central Bohemia (e.g., the Berounka river valley) and southern Bohemia. It probably still occurs at many of them.
