  Thallus crustose to areolate, effuse, formed by the prothallus and 1) partly by minute round to irregular areolae, ±closely contiguous and sometimes appearing as a continuous crust and 2) partly by isidia developing directly from the prothallus; isidia usually dominating. Prothallus indistinct to well developed, white to pale reddish brown. Areolae c. 0.05–0.10 mm wide, adnate, ±isodiametric, mostly slightly convex, pale yellow to yellow-brown or green, glabrous or rarely pubescent along the margins. Isidia usually abundant, moderately thick, subglobose to cylindrical, medium to dark green, often with a yellow or brown tinge, glabrous, simple to branched or occasionally coralloid. Upper cortex of type 2, 5–15 μm thick. Apothecia rare, 0.6–1.2 mm diam., rounded to irregular, plane to moderately convex, ±conglomerate, tan to reddish brown or orange-pink, with a paler margin that is reduced or excluded in convex apothecia. Proper exciple yellow. Epihymenium colourless. Hypothecium yellow to yellow-brown. Ascospores simple, narrowly ellipsoidal to fusiform, 8–14 × 2–3 μm. Pycnidia not seen.
CHEMISTRY: Cortex and medulla K–, C–, KC–, P–, UV–; no lichen substances detected.
  Known from northern N.T., eastern Qld and N.S.W.; common on the bark of various trees and on moist rocks in rainforest and coastal forest. Also on Lord Howe Island and Norfolk Island.
