Lobothallia alphoplaca (Wahlenb.) Hafellner

A conspicuous Lobothallia with a placodioid thallus, that usually grows on sun-lit natural basic outcrops, typically diabases and calcareous conglomerates. The lichen may be found also on serpentinites or other types of calcium-enriched siliceous rocks. In the Czech Republic, Lobothallia alphoplaca behaves as a lowland thermophilous species. More of its localities are known only from the broader surroundings of Prague and Brno. The smaller brown thalli are sometimes mistaken for L. praeradiosa (see the species description).
