Distribution:
Description: Thallus crustose, episubstratic, areolate-subsquamulose, 2-3 cm wide, 1-1.5 mm thick, chalky white, consisting of 1.5-8 mm wide, subsquamulose areoles with an irregular, usually slightly papillose surface, the marginal ones often slightly elongate. Cortex 30-90 µm thick, of anticlinally arranged hyphae, containing crystals visible under polarized light; algal layer irregular; medulla thick, white, lax, filled with crystals. Apothecia aspicilioid, immersed in the thallus, 1-8 per areole, sometimes confluent, often of irregular outline, 0.2-0.8 mm wide, with a concave to finally flat, blue-grey-pruinose disc and a poorly evident margin. Epithecium 20-40 µm high, 2-layered, the upper layer grey, consisting of a layer of crystals (pruina) the lower layer brownish green, N-; hymenium colourless, 80-95 µm high, I+ blue then reddish; paraphyses branched and anastomosing, strongly coherent, 3-6 µm thick, the apical cells only slightly swollen; hypothecium colourless, devoid of crystals, subtended by an algal layer. Asci 8-spored, cylindrical-clavate, the thin outer coat K/I+ blue, the wall and apical dome K/I-. Ascospores 1-celled, hyaline, broadly ellipsoid, 11-15 x 7-10 µm, the wall 0.5-1 µm thick. Photobiont chlorococcoid. Spot tests; cortex and medulla K-, C-, KC-, P-. Chemistry: without lichen substances.
Note: on various types of calciferous rocks (limestone, dolomite); reported from the lowlands to the subalpine belt in the Alps, outside the Italian territory; to be looked for in Italy.
