  Thallus endophloeodal to epiphloeodal, to c. 600 µm thick, pale greenish grey to pale olive, dull to slightly glossy, smooth to grainy-speckled, continuous to rugose or slightly verruculose, ±rimose. Protocortex discontinuous, to c. 20 µm thick. Algal layer well developed, continuous; calcium oxalate crystals abundant, moderately large to large, scattered or clustered, occasionally in columns. Vegetative propagules not seen. Ascomata ±conspicuous, to c. 1.5 mm diam., ±rounded to irregular, especially in fused ascomata, apothecioid, occasionally erumpent, solitary to fused or distinctly clustered, with several ascomata sharing a common thalline rim, immersed to moderately emergent, then hemispherical to conical. Disc with the columella visible from above, distinctly pruinose, off-white to yellowish, often fused with the thalline rim, entire to reticulate, especially in clustered ascomata. Proper exciple not visible from above; thalline rim margin to 1 mm diam., ±rounded to irregular, entire to coarsely split, thick, concolorous with the thallus to off-white or brownish; thalline rim incurved. Proper exciple fused, thin, pale yellowish to yellowish brown internally, orange to reddish brown or brownish marginally, often dark brown, rarely slightly carbonised towards the tips, non-amyloid. Hymenium to c. 160 µm thick, not inspersed, distinctly conglutinated; paraphyses straight to slightly bent, ±interwoven, unbranched, with unthickened tips; columellar structures well developed, to 400 µm wide, entire to distinctly complex, especially in fused ascomata, yellow-brown to dark brown, non-carbonised, covered with a ±thick layer of greyish granules. Epihymenium hyaline, with greyish or brownish granules. Asci 8-spored; tholus initially thick, thin when mature. Ascospores transversely septate, oblong to fusiform or ellipsoidal, with ±rounded to narrowly rounded, rarely subacute ends, hyaline, distinctly amyloid, 15–35 × 9–10 µm, with 6–10 locules; locules ±rounded to slightly angular in younger stages, ±lentiform to oblong or rectangular, with hemispherical to conical end cells; septa moderately thick, regular; ascospore wall thick, non-halonate; endospore thick. Pycnidia not seen.
  Occurs on bark in eastern Qld, at altitudes to 900 m; pantropical.
