Description: Thallus crustose, episubstratic, thick, continuous to rimose or areolate, whitish grey to pale brown, often with a pruinose appearance, the areoles smooth to granulose-verrucose, flat to convex. Apothecia lecanorine, 0,5-0.8(-1) mm across, adnate to sessile, with a dark brown to black, flat to weakly convex disc, and a thick, smooth to slightly warted, persistent thalline margin. Epithecium reddish brown, 10-20 µm high; hymenium colourless, up to 120 μm high, not inspersed with oil droplets; paraphyses 1.5-2.5 µm thick at mid-level, the apical cells swollen, 4-7 µm wide, with a dark cap; hypothecium colourless, without oil droplets. 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, ellipsoid, (16-)20-26 x 10-16 μm, Tunicata-type i.e. with a thick outer wall, and lumina thus appearing double-walled, the torus absent, with ontogeny of both type A and type B. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a southern species found on the top of sun-exposed boulders of dolomite, limestone and calcareous schists, with a rather wide altitudinal range.
