Description: Thallus crustose, episubstratic, ochraceous yellow to ochraceous orange, epruinose, smooth and subcontinuous or sometimes finely cracked, usually well-delimited, forming up to 3 cm wide patches. Apothecia frequent, 0.3-0.8(-1) mm across, persistently immersed in the thallus, with an initially flat, then sometimes convex, orange to brownish orange disc and a usually slightly paler, smooth, persistent margin. Epithecium orange, granular, K+ purple-red; hymenium colourless, 50-80 μm high; paraphyses sparingly branched in upper part, the apical cells swollen, up to 4-6 μm wide; hypothecium colourless. Asci 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 to broadly ellipsoid, 9-15 x 5-10 μm, the equatorial thickening (“septum”) 3-5 μm (1/4-1/2 of spore length). Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-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).
