Description: Thallus crustose-placodioid, episubstratic, ochraceous to pale salmon-pink, more or less covered in a whitish pruina, forming orbicular, strongly convex 0.5-1(-1.5) cm wide rosettes. Lobes convex, contiguous, 1.5-2.5 mm long, 0.7-1.5 mm wide; central part of thallus consisting of convex areoles. Cortex absent or poorly developed; medulla white. Apothecia frequent, lecanorine, 0.6-2.5 mm across, at first half immersed but soon becoming sessile and slightly constricted at base, round but often deformed by mutual compression, with a concave to flat, pale brown to black disc more or less covered in a bluish-white pruina, and a thick thalline margin. Epithecium dark green-brown, at least in young apothecia inspersed with crystals not dissolving in K; hymenium and hypothecium colourless; paraphyses simple or sparsely branched, slightly swollen at apex. Asci 8-spored, elongate-clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, broadly ellipsoid, thin-walled, (8-)9-10(-12) x (3.5-)4-5.5(-6.5) µm. Photobiont chlorococcoid. Spot tests: thallus K+ orange yellow, C+ orange, KC+ orange, P-, UV+ orange; disc of apothecia C-, but C+ orange in young, heavily pruinose apothecia. Chemistry: arthothelin, 2,7-dichloronorlichexanthone.

Note: under overhangs or on steeply inclined surfaces of calcareous rocks in upland areas; widespread both in the Alps and in the mountains of Southern Italy.
