  Thallus irregularly spreading, somewhat entangled, loosely attached centrally, 5–15 (–30) cm wide; margins free, ±ascending. Lobes linear-elongate, dichotomously branching, often widely divergent at apices, 2–6 (–10) cm long, 2–15 (–30) mm wide, plane to canaliculate; lobe margins entire, thickened-ridged below (×10 lens), without projecting pseudocyphellae. Upper surface grey-green to olive-brownish when dry, lettuce-green when wet, shallowly to deeply faveolate; without isidia, maculae, phyllidia, pseudocyphellae or soredia. Medulla white. Photobiont green. Lower surface wrinkled to bullate, pale and glabrous at margins, darker centrally, with a scattered to uniform tomentum. Pseudocyphellae minute, white, Apothecia marginal, rarely laminal, sessile, 0.5–5 mm diam.; disc dark red-brown to black, epruinose; exciple corrugate-scabrid, pale buff to red-brown. Ascospores ellipsoidal,
1-septate, 25–32 (–38) × 9–11.5 μm, brown or grey; walls thickened. CHEMISTRY: Methyl evernate, tenuiorin, 2"-O-methyltenuiorin, 2',2"-di-O-methyltenuiorin, methyl gyrophorate, methyl lecanorate, gyrophoric acid (trace), norstictic acid, stictic acid, cryptostictic acid (trace), 9α-acetylconstictic acid (trace), constictic acid and zeorin.
  Occurs in S.A., eastern N.S.W., Vic. and Tas.; grows on living and dead wood, tree trunks, canopy branches and shrubs in sheltered forest, occasionally also on rocks in ±open forest, at altitudes of 200–1540 m. Widespread in New Zealand from latitude 35°S southwards to the Auckland Is. and Campbell Is.
