| Thallus 3–10 (–20) cm wide, monophyllous or polyphyllous; lobes irregular; margins entire. Upper surface dull, typically finely areolate-scabrid, medium to dark brown or grey to black, wholly or partially covered with a thin to thick white necral layer; naked areas maculate or not. Isidia and soredia absent. Lower surface mostly smooth to weakly areolate, especially in blackened areas near the umbilicus, pinkish to beige-brown to black, with or without patchy sparse grey pruina. Rhizinomorphs abundant on upper and lower surfaces and marginal,
0.5–1.5 (–3.0) mm long, black, mostly terete, richly branched, shrubby to ±coralloid, frequently forming a dense fringe; thallyles frequent, most commonly on rhizinomorphs on lower surface. Thalloconidia sparse to abundant, at apices of rhizinomorphs, multicellular, ±globose, (15–) 20–40 (–60) µm wide; individual cells 5–10 µm wide. Apothecia occasional to frequent, marginal or scattered over the upper surface, (0.5–) 1–3 (–4) mm diam., substipitate, occasionally coronate; disc gyrose, plane to convex, black. Ascospores simple, ellipsoidal to oblong-ellipsoidal, 12–18 × 6–9 µm, hyaline. Pycnidia scattered, immersed, visible as black dots on the upper surface. Conidia bacilliform to fusiform, 3–4 × 0.5–0.7 µm. CHEMISTRY: Medulla K–, C–, KC–, P–; no substances detected by TLC. |

| Occurs in N.S.W., A.C.T., Vic. and Tas., on rock outcrops in subalpine and alpine habitats. Also in Europe, Asia, Africa, South America, New Zealand and Antarctica. | ||
