  Thallus endophloeodal to epiphloeodal, to c. 600 µm thick, pale greenish grey to yellowish grey or pale olive, dull to glossy, smooth, continuous to verrucose or verruculose, rimose or not. True cortex ±continuous, to c. 40 µm thick, formed by irregular hyphae. Algal layer well developed, continuous; calcium oxalate crystals small to moderately large, scattered or clustered. Vegetative propagules not seen. Ascomata conspicuous at maturity, to c. 0.6 mm diam., ±rounded to irregular, becoming apothecioid, solitary to fused, immersed to somewhat emergent, rarely strongly emergent, often verrucose, hemispherical to urceolate. Disc with the columella visible at maturity, epruinose to ±distinctly pruinose, off-white to brownish or dark grey, free, entire. Pores formed by the thalline rim margin, to c. 0.4 mm diam., ±rounded to irregular, moderately thin to thick, occasionally depressed, entire to split and/or evanescent, brownish to dark grey due to the protuberant proper exciple, otherwise concolorous with the thallus or brighter; thalline rim incurved. Proper exciple fused, moderately thin to thick, yellowish brown to brownish internally, dark brown, rarely carbonised marginally and above, often amyloid at the base. Hymenium to c. 120 (–150) µm thick, not inspersed, distinctly conglutinated; paraphyses straight to slightly bent, interwoven, unbranched, with slightly thickened tips; columellar structures well developed at maturity, to 300 µm wide, entire, brownish to carbonised, with or without a ±thick layer of greyish granules. Epihymenium hyaline, sometimes with greyish or brownish granules. Asci 8-spored; tholus initially thick, becoming thin. Ascospores transversely septate, rarely with a single longitudinal septum, oblong to fusiform or ellipsoidal, with ±rounded to narrowly rounded or subacute ends, hyaline, amyloid, 15–35 (–40) × 7–10 (–12) µm, with 4–10 (–12) locules; locules initially ±rounded to slightly angular, then ±lentiform to oblong or rectangular, with hemispherical to conical end cells; septa thick, regular; ascospore wall and endospore moderately thick; wall non-halonate. Pycnidia not seen.
CHEMISTRY: Thallus K+ yellowish brown, C–, P+ orange-red; containing protocetraric acid (major), conprotocetraric acid (trace), fumarprotocetraric acid (trace), virensic acid (trace).
  Corticolousin lowland to montane rainforest and wet-sclerophyll forest in eastern Qld and north-eastern N.S.W.; mainly pantropical.
