  Thallus variable, forming orbicular to irregular patches, to 12 cm wide, generally much smaller. Lobes mostly hollow, varying from very loose and attenuate to moderately compact; older central lobes and true marginal lobes broader, more compact, adhering to substratum; secondary lobes dichotomously branched, attenuate, 0.5–3 mm wide. Upper surface grey to off-white; granular soredia developing near apices, spreading, becoming diffuse over whole surface, rarely developing into coralloid sorediate isidia. Medulla thin to thick. Lower surface strongly wrinkled, glossy, pale brownish at apices of young lobes. Apothecia rare; disc to 5 cm wide, pedicellate, reddish brown; receptacle ribbed, funnel-shaped. Ascospores 7–10 × 4.5–6 µm. CHEMISTRY: cortex K+ yellow; medulla KC+ red, P± red. Atranorin, chloroatranorin, physodic acid (major); 3-hydroxyphysodic acid (minor); 2'-O-methylphysodic acid, alectoronic acid, physodalic acid and protocetraric acid (present or absent).
  Widespread and common in humid and temperate forests in south-western W.A., S.A., south-eastern Qld, N.S.W., A.C.T., Vic. and Tas.; grows on dead wood, bark, twigs and rocks. Common in South America and New Zealand.
