  Thallus rosette-forming to irregularly spreading, loosely attached centrally, 3–10 (–20) cm wide. Lobes very variable, shortly linear-laciniate to broadly rounded, 1–5 (–10) cm long, 2–25 mm wide, discrete to imbricate, concave to plane; lobe margins entire, incised, crenate-dentate, often densely phyllidiate, sinuous, ascending at apices, slightly thickened below, occasionally with minute yellow pseudocyphellae. Upper surface olive-brown, red-brown to glaucous brown (reddish or ±blackened in exposed habitats) when dry, blue-grey suffused red-brown when wet, wrinkled to faveolate, rather coriaceous; without isidia, maculae, pseudocyphellae or soredia, moderately to densely phyllidiate. Phyllidia mainly marginal, also laminal on ridges and regenerating from cracks in upper surface, simple to coralloid, to 1.5 mm tall, often eroding apically and exposing medulla. Medulla yellow-white. Photobiont Nostoc. Lower surface pale buff to brown and glabrous at margins, black and tomentose centrally. Pseudocyphellae scattered, sparse to frequent, round to irregular, slightly sunk in tomentum, yellow. Apothecia uncommon, marginal and laminal, 0.5–3.5 mm diam.; disc dark red-brown to black, matt, epruinose; exciple pale red-brown, corrugate-scabrid; epithecium pale to dark yellow-brown or olive-brown, dissolving in K; hymenium pale straw-yellow; hypothecium pale yellow-brown, dissolving in K. Ascospores broadly ellipsoidal, 1–3-septate, 20–25 × 7–9 µm, yellow-brown to dark red-brown. CHEMISTRY: Retigeranic acid, pulvinic dilactone, calycin, tenuiorin, pulvinic acid,
2-O-acetyltenuiorin, methyl gyrophorate, hopane-6α,7β,22-triol (major), 6α-acetoxyhopane-7β,22-diol (minor), 7β-acetoxyhopane-6α,22-diol (trace), hopane-7β,22-diol (minor), 7β-acetoxyhopane-22-ol (trace), 15α-acetoxyhopane-22-ol (trace), norstictic acid (trace), stictic acid, salazinic acid (trace) and constictic acid.
  Occurs in all States and Territories except N.T., most common in south-eastern Australia; grows on rock, bark and dead wood from sea level to 1500 m. Also in New Zealand, southern South America and the Palaeotropics.
