  Thallus orbicular, to 15 cm wide, the older central lobes and true marginal lobes adherent to substratum, crowded or contiguous, 3–10 mm wide, often with peripheral and secondary lobes which are linear, suberect, elongated, 1–2 mm wide, lacking lateral contacts and occasionally cartilaginous; dichotomously branched linear lobes sometimes dominant. Upper surface with laminal wrinkles, grey; upper cortex erupting, sorediate, finally covered with granular soredia often in confluent glomerules 3–5 mm wide. Medulla mostly solid, blanching in older, highly sorediate specimens. Lower surface strongly wrinkled, pale brown or off-white near the apices. Apothecia rare, subpedicellate; receptacle sorediate, funnel-shaped; disc 3–12 mm wide, concave becoming flat, red-brown; thalline exciple entire then sorediate. Ascospores 6–9 × 4–5 µm. CHEMISTRY: cortex K+ yellow; medulla KC+ red, P± red. Atranorin, chloroatranorin, physodic acid (major); 3-hydroxyphiodic acid, 2'-O-methylphysodic acid (minor); alectoronic acid, physodalic acid and protocetraric acid (present or absent).
  A common species of temperate forests of W.A., S.A., N.S.W., A.C.T., Vic. and Tas., extending into subalpine forests in N.S.W., A.C.T., Vic. and Tas.; grows on dead wood, bark and occasionally rocks. Also in New Zealand and Japan.
