Description: Thallus crustose, episubstratic, yellow-green, areolate, forming up to 12 cm wide patches delimited by a black prothallus which is often visible also as a hypothallus between areoles. Areoles angular, 0.3-0.7 mm wide, contiguous, flat to slightly convex, smooth, epruinose. Cortex 30-60 µm thick, poorly differentiated; medulla white, I+ blue. Apothecia frequent, lecideine, arising between the areoles, usually angular, to 0.7(-1) mm across, with a black, weakly concave to weakly convex, epruinose disc and a very thin, usually soon excluded proper margin. Proper exciple pale brown to brownish red; epithecium reddish brown to reddish violet, K+ distinctly purple-red; hymenium colourless, 100-180 µm thick, K/I+ blue; paraphysoids strongly coherent, richly branched and anastomosing, the apical cells clavate; hypothecium dark brown, K-. Asci 8-spored, clavate, fissitunicate, with a well-developed tholus that is K/I- in lower part and K/I+ blue near the apex, lacking an ocular chamber, Rhizocarpon-type. Ascospores muriform, with 12-15(-20) cells visible in optical view, soon becoming dark green to brown, ellipsoid, (20-)25-40 x (10-)12-22 µm, halonate at least when young. Photobiont chlorococcoid. Spot tests: medulla K-, C-, KC-, P+ yellow. Chemistry: cortex with rhizocarpic acid; medulla with psoromic acid; epithecium with low amounts of gyrophoric acid. Note: on siliceous rocks; most common in the Mediterranean mountains, but also found in the Alps in dry-warm areas, closely related to Rh. geographicum.
