  Thallus fragile, orbicular or irregularly spreading, to 20 cm wide, loosely attached to substratum. Lobes 1–2.5 mm wide, rarely to 4 mm, the branching dichotomous or trichotomous to ±irregular; esorediate. Upper surface grey to white, usually with black lines, bands and patches; margins often blackened, not always sharply delimited from lower surface. Medulla thin, hollow, darkened or not. Lower surface deeply and persistently wrinkled, with occasional apical perforations, shining. Apothecia sparse to moderately common, 2–10 mm wide; disc concave becoming ±flat, dark brown; thalline exciple entire to crenate. Ascospores 5–8 × 4–6 µm. CHEMISTRY: cortex K+ yellow; medulla KC+ red, P+ red. Atranorin, chloroatranorin, physodic acid, physodalic acid (major); protocetraric acid, 2'-O-methylphysodic acid, alectoronic acid, 3-hydroxyphysodic acid and vittatolic acid (present or absent).
  Occurs in W.A., N.S.W., A.C.T., Vic., Tas. and Macquarie Is.; grows on shrubs, rocks, grasses and soil. Common in the Falkland Islands, South Georgia, southern South America, New Zealand, and the high mountains of Papaua New Guinea.
