Description: Thallus crustose, whitish, ochraceous to medium brown, quite variable, continuous and endosubstratic or episubstratic and rimose-areolate, the areoles 0.5-0.8 mm wide, flat, smooth or somewhat rugose, without a distinct prothallus. Apothecia lecanorine to rarely pseudolecanorine, 0.3-0.5(-0.7) mm across, immersed in the rock to subsessile, with a concave to slightly convex, dark brown to black, at first often whitish-grey-pruinose disc, a thin, entire, persistent to partly excluded thalline margin, and a rather thick, entire, persistent proper margin. Thalline exciple (40-)60-120 µm wide, corticate; proper exciple 10-15 µm wide laterally; epithecium red-brown, K-; hymenium colourless, not inspersed with oil droplets, 70-90(-100) µm high; paraphyses 2-3.5 µm thick at mid-level, the apical cells 4-6 µm wide, with a dark cap; hypothecium colourless to pale yellow, 70-100 µm high. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, brown, broadly ellipsoid, (10-)11-14(-15) x (6.5-)8.5-9(-11) µm, Bicincta-type, the outer wall not ornamented, thickened at septum and apices in young spores, the lumina soon rounded, with a pigmented band around each cell, with ontogeny of type A (apical wall thickening after septum formation). Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus with zeorin. Note: on sun-exposed calcareous outcrops in upland areas; certainly present also in the Alps.
