Description: Thallus crustose-placodioid, episubstratic, forming orbicular to irregular, strongly white-pruinose, 2-5 cm wide rosettes. Lobes mostly flattened, contiguous, radiating, 0.4-0.8(-1.4) mm wide, chalky white, sometimes glaucous-white at margins. Cortex colourless, with abundant crystals insoluble in K; medulla white, with a few crystals only. Apothecia frequent, lecanorine, subsessile, 0.8-2 mm across, with a flat, dark brown to black, usually slightly pruinose disc and a thin, white-pruinose, finally sometimes excluded thalline margin. Epithecium brownish; hymenium colourless, 50-70 µm high, K/I+ blue; paraphyses simple, coherent, not markedly capitate; hypothecium colourless, 110-140 µm high. Asci 8-spored, cylindrical-clavate, with a K/I+ blue outer coat and a K/I+ uniformly blue apical dome, approaching the Catillaria-type. Ascospores: 1-septate, hyaline, narrowly ellipsoid to almost acicular, sometimes slightly curved, (10-)12-17(-20) x 2.5-5 μm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-, UV+ greenish grey; medulla P+ orange-red. Chemistry: medulla with pannarin and zeorin (both major). Note: a Mediterranean to mild-temperate species found on calcareous boulders, most often on horizontal faces; more heliophytic in Northern than in Southern Italy, where it often occurs in sheltered situations.
