  Thallus squamulose, orbicular to irregularly spreading, to 10 cm wide, with a conspicuous, marginal black prothallus. Squamules closely attached, imbricate and clustered, occasionally ascending or ±coralloid, 0.2–1.5 mm wide. Upper surface smooth, greyish to brownish. Cyanobiont Nostoc, in clusters. Apothecia frequent, sessile, to 1.5 mm wide; disc flat, ±waxy, usually distinctly gyrose with several concentric bands of sterile tissue, centrally often perforate, yellowish to orange-brown; thalline exciple prominent, crenulate, inflexed. Ascospores 10–18 × 5–10 µm; exosporium smooth to warted.
  Occurs on bark, on moss or on rock. A species of moist, ±lowland forests, rarely collected in Qld, N.S.W. and Tas., but probably overlooked as it is quite common and widespread in New Zealand; also in New Caledonia.
