Description: Thallus squamulose to subcrustose-placodioid, bright yellow-green, sometimes with brownish patches, very thick. Squamules convex, contiguous, wrinkled, to 3 mm broad, the marginal ones to c. 1 cm long, developing on a black prothallus. Upper surface inspersed with yellowish granules, later covered by a thick epinecral layer; lower surface black, attached by numerous bundles of black rhizinoids. Medulla white in upper part, dark brown in lower part, thick, I-. Apothecia frequent, lecideine to biatorine, rounded, sessile, up to 2 mm across, developing among the squamules, with a black, flat to convex disc, and a thin, concolorous, soon excluded proper margin. Proper exciple dark reddish brown; epithecium dark olive-green to blackish, K-, N+ red; hymenium colourless, I+ blue; paraphysoids densely branched and anastomosing from the base, the apical cells hardly swollen; hypothecium dark, of radially arranged hyphae. Asci 8-spored, clavate, with a I+ blue outer gelatinous coat, thickened at apex, with an internal I+ deep blue cap. Ascospores 0-1(-3)-septate, the central septum with an internal torus, brown, ellipsoid with rounded ends, 12-18 x 7-10 μm, without a gelatinous perispore. Photobiont chlorococcoid. Spot tests: thallus K- , C-, KC-, P+ yellow-orange, UV+ orange. Chemistry: two pulvinic acid derivatives and additional unknown compounds.
