  Thallus rosette-forming to irregularly spreading, loosely attached centrally, 5–10 (–30) cm wide. Lobes broadly rounded (10–17 mm wide) to narrowly laciniate (2–6 mm wide), discrete from apices to centre, to complex-imbricate; lobe margins entire, sinuous to crenulate or ragged, becoming isidiate or eroding with age. Upper surface pale greenish to yellow-fawn or ±blackened when dry, lettuce-green to greenish yellow (usnic acid) when wet, undulate, shallowly wrinkled, never faveolate, often deeply cracked; without maculae, phyllidia, pseudocyphellae or soredia. Isidia marginal or arising from laminal cracks, simple, terete, 0.5–1 mm tall. Medulla white. Photobiont green. Lower surface pale buff or whitish at margins, black or dark brown centrally, tomentose throughout or ±glabrous at margins. Pseudocyphellae prominent, white. Apothecia rare, sessile to subpedicellate, 0.5–7 mm diam.; disc pale to dark red-brown, epruinose; exciple prominent, pale buff or pinkish or whitish, scabrid-areolate, obscuring disc when young; epithecium pale yellow-brown to red-brown, dissolving in K; hymenium colourless; hypothecium pale orange-brownish to pale straw-yellow. Ascospores fusiform, 1–3-septate, (13.5–) 15.5–20.5 (–22.5) × 4.5–7 µm, pale yellow-brown. CHEMISTRY: 7β-acetoxyhopane-22-ol (major), hopane-7β,22-diol (trace), hopane-15α,22-diol (major), norstictic acid (trace), stictic acid (major), cryptostictic acid (trace), constictic acid (major), methyl stictic acid (minor), 9α-acetoxyconstictic acid (minor) and usnic acid.
     
  Occurs in eastern N.S.W., southern Vic. and Tas. Common on rocks, peat, bark and decorticated wood or over bryophytes in heaths and forest. Also in Lord Howe Is. and Macquarie Is., and in New Zealand and its subantarctic islands and southern South America.
