| Thallus orbicular to irregular, closely to loosely attached centrally, 2–8 (–12) cm wide. Lobes variable, broadly rounded to laciniate, often deeply dissected or folded, complex-imbricate centrally; margins sinuous, irregularly notched or torn, rather ragged, densely isidiate. Upper surface pale grey to chestnut-brown when dry, grey-black suffused red-brown when wet, wrinkled, pitted, punctate-impressed to ±faveolate in parts, isidiate, maculate, without soredia. Isidia minute, styliform, granular to coralloid-branched, dark brown or grey-brown, glossy, densely crowded in a thick marginal crust, occasionally in small laminal clumps or forming a more diffract laminal crust. Photobiont Nostoc. Lower surface dark brown to black, paler at margins, thickly tomentose, sometimes with tufts of long black anchoring hyphae projecting near margins and scattered over lower surface. Cyphellae scattered, (0.1–) 0.5–1.5 (–3) mm diam., deeply sunk in tomentum; pit membrane white to pale fawnish. Apothecia not seen. |  |

| Apparently rare in north-eastern Qld on trees in montane rainforest, and in eastern N.S.W. Still very poorly known in Australia, it also occurs widely in tropical and southern-temperate regions. | ||
