Description: Thallus crustose, episubstratic, rather thick, dark grey-brown with a faint violet tinge, continuous to rimose-areolate, forming up to 12 cm wide patches or mosaics, often delimited by a dark hypothalline line. Apothecia cryptolecanorine to lecideine, subinnate, 0.5-1.5 mm across, with a flat to slightly convex, black disc, a thin, entire, soon excluded thalline margin, and a persistent, prominent proper margin. Proper exciple dark brown in outer part, paler brown within, 45-90 μm wide laterally; epithecium brown, C+ red; hymenium colourless, 75-120 μm high; paraphyses 1-1.7 μm thick at mid-level, the apical cells 3.5-5 μm wide, with a brown cap; hypothecium pale brown, 70-155 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, 15-23 x 7,5-13 µm, Milvina-type, tending towards the Physcia-type. Photobiont chlorococcoid. Spot tests: thallus K-, C+ pink, KC+ pink, P- (reactions best visible on a thick section under the microscope). Chemistry: gyrophoric acid, zeorin.
Note: a Mediterranean-Atlantic lichen described from Tuscany, found on hard siliceous rocks subject to frequent humid winds, often near the coast; not uncommon in some parts of Mediterranean Italy, e.g. in Sardinia, on nuraghes.
