  Thallus rosette-forming to irregularly spreading, loosely to closely attached centrally, 5–10 (–15) cm wide. Lobes ±linear-laciniate, 1–4 (–8) cm long, 3–8 (–12) mm wide, discrete or contiguous from margins to centre or ±complex-imbricate, subdichotomously to irregularly branched, tough, coriaceous when dry, flabby when wet, without isidia; lobe margins entire to variously notched, crenate, incised or ±pectinate, thickened above and below, without projecting pseudocyphellae. Upper surface pale greenish yellow to pale buff when dry, lettuce-green or olive suffused yellowish when wet, undulate, irregularly wrinkled or pitted to subfaveolate, occasionally minutely tomentose at apices; without maculae, phyllidia, pseudocyphellae or soredia. Medulla yellow. Photobiont green. Lower surface yellow at margins, red-brown centrally, wrinkled-puckered at margins, uniformly tomentose or ±glabrous at margins; tomentum thin to thick and felted, white to red-brown. Pseudocyphellae scattered, round to irregular, conical-verruciform, to 0.2 mm diam., yellow. Apothecia occasional, marginal, subpedicellate, 1–4 (–6) mm diam.; disc pale to dark red-brown, epruinose; exciple coarsely scabrid-corrugate, concolorous with thallus or paler, obscuring disc at first, persisting as a stellate crenulate margin; epithecium pale red-brown; hymenium colourless; hypothecium opaque, yellow-brown. Ascospores acicular, 3–6-septate, (58–) 65–90 (–104) × 3–5.5 µm, colourless. CHEMISTRY: Pulvinic acid, pulvinic dilactone, calycin, pulvinamide, pseudocyphellarin A, isopseudocyphellarin A, phenarctin, 2α,3β,22α-triacetoxystictane, 22α-hydroxystictane-3-one, 2α,3β-diacetoxystictane-22-ol, stictane-3β,22α-diol, 2β-acetoxystictane-3β,22α-diol, 3β-acetoxystictane-2α,22α-diol and stictane-2α,3β,22α-triol.
