| Thallus orbicular to irregularly spreading, 4–9 (–15) cm wide, coriaceous, variously lobed. Lobes sublinear to irregularly branched, initially ±flattened, contiguous and closely attached centrally, becoming palmate (to 5 cm long and 1.5 cm wide), imbricate and elongate-spreading, ascending at apices and growing outwards; margins entire, occasionally irregularly scalloped at the apices or becoming phyllidiate, sometimes sinuous. Upper surface olive-brown to reddish (chestnut)-brown to greyish red or grey (shade forms), matt or glossy in parts, markedly faveolate-reticulate (especially the fertile lobes), or with coarse terete to squamiform phyllidia along ridges between faveolae at lobe margins and fringing margins of apothecia; faveolae 2–3 mm wide, to 2 mm deep, separated by rather well-defined or, occasionally, sharp chipped ridges, less pronounced on dorsal side of apothecia, ±white-maculate (×10 lens; especially the sterile lobes); maculae stellate or forming a raised white sulcate reticulum; isidia absent. Medulla white. Photobiont Nostoc. Lower surface of fertile lobes distinctly bullate, glossy, creamish buff at the margins, glabrous; sterile lobes dark grey-brown centrally, wrinkled, occasionally pubescent. Apothecia elongate-rounded to reniform, rarely shallowly lobed or dividing into separate discs, 5–10 (–15) mm wide, 2–5
(–8) mm long; disc pale to dark (red-)brown, initially sunken, becoming slightly raised, with a narrow entire margin; apices of apothecia usually inrolled, entire or denticulate. Ascospores 3-septate, (14.0–) 17.5–22.5 (–25.0) × 5.0–8.5 μm, pale brownish. Pycnidia rare, marginal, semi-immersed. Conidia not seen. CHEMISTRY: Hopane-6α,22-diol (major), perlatolic acid (major), stenosporic acid (minor), glomelliferic acid (major), ±traces of glomellic, anziaic and loxodellic acids, ±trace of unidentified pigment. |

| Occurs in N.S.W., Vic. and Tas.; corticolous, saxicolous or muscicolous in cool-temperate rainforest, heathland and Sphagnum bog, high-altitude mixed sclerophyll and open or scrubby Eucalyptus forest. Also in southern South America, Juan Fernández Islands and New Zealand. | ||
