Upper surface grey-green, shining, ridged-rugose or smooth, convex or becoming flat, occasionally white-blotched, especially at apices, weakly concave towards lobe ends. Upper side of cavity densely yellow or ochre-yellow, tomentose towards lobe ends, blackened centrally. Perforations sparse, scattered, gaping or with depressed rim, level or slightly raised. Soralia numerous, laminal, rarely subterminal, scattered or ±confluent, convex, finely granular, to 1 mm wide. Apothecia rare, adnate, 3–4 mm wide, concave; disc epruinose, ±wrinkled, red-brown; exciple thick, inflexed, smooth, rarely faintly white-blotched, becoming entirely sorediate. Ascospores 8 per ascus, ellipsoidal, 28–35 × 15–18 µm; wall 2 µm thick. CHEMISTRY: atranorin (cortex), stictic, constictic, norstictic (trace) and echinocarpic acids, accessory compounds and four or more orange-yellow pigments, one UV+ orange-red; medulla K+ orange, C-, KC+ orange, P+ orange.
