  Thallus foliose, adnate, coriaceous, to 3–10 cm wide. Lobes contiguous centrally to separate at the periphery, imbricate, sublinear-elongate, dichotomously to subdichotomously branched, 0.5–2 mm wide; eciliate. Upper surface ±convex, dull, faintly maculate, smooth or becoming cracked, lacking isidia. Lower surface pale brown to tan; primary rhizines moderately dense, scattered, with a thick mass of fine, pale tan, densely branched or agglutinated secondary rhizines developing from primary rhizines or lower surface. Apothecia common, to 2 mm wide; disc ±flat or shallowly concave, pale brown to cinnamon-brown. Ascospores 5–7 × 3–5 µm. Pycnidia common. Conidia fusiform to bacilliform, 5–7 × 1 µm. CHEMISTRY: cortex K-, UV-; medulla K- or K+ pale brown, C-, KC+ pale brown, P+ orange-red; containing usnic acid, atranorin, protocetraric acid and ±protolichesterinic acid.
  This rare species is found on the bark of mangroves and in the canopy of trees in coastal rainforests in north Qld. It is common in dipterocarp forests in the Andaman Is., the Philippines, Thailand, West Malaysia, Sabah, Indonesia and Papua New Guinea.
