Description: Thallus crustose, episubstratic, yellow to yellow-orange, areolate-subsquamulose, without a distinct prothallus. Areoles of very different sizes and shapes, from granulose to subsquamulose, (0.3-)1-3(-4) mm wide, dispersed or contiguous, the smaller ones usually convex, otherwise flat or with an irregular-wrinkled surface, the peripheral ones sometimes elongate and/or lobulate at margin. Apothecia zeorine, sessile, 0.3-0.5(-0.6) mm across, with an orange, concave to flat disc, and a smooth to crenulate, persistent proper margin. Proper exciple prosoplectenchymatous, 120-150 µm wide; epithecium brownish yellow, 10-15(-20) µm high, K+ red; hymenium colourless, 90-120 µm high; paraphyses simple or forked, 1.5-2 µm thick at mid-level, the apical cells 3-5 µm wide; hypothecium colourless. Asci (4-)6-8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 14.5-20(-23) x 5-7(-8) µm, the equatorial thickening (“septum”) 1-3(-4) µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: thallus and apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997). Note: a species ranging from Central Asia to the Mediterranean Region, found on sun-exposed calcareous, more rarely basic siliceous rocks wetted by rain in at least seasonally dry habitats. Most records from southern Europe, including those from Italy, need to be checked.
