  Thallus endophloeodal to epiphloeodal, to c. 600 µm thick, pale greenish to yellowish green or pale olive, ±glossy, smooth, continuous to ±verruculose, mainly non-rimose. True cortex continuous, to c. 40 µm thick, yellowish, consisting of periclinal hyphae. Algal layer well developed, continuous; calcium oxalate crystals sparse to abundant, small and scattered, rarely clustered; distinct medulla often present at ascomatal margin. Vegetative propagules not seen. Ascomata ±conspicuous, to c. 1.5 mm diam., ±rounded, apothecioid, solitary to marginally fused, immersed, rarely strongly emergent, mostly hemispherical, occasionally somewhat flattened. Disc with the columella visible from above, distinctly pruinose, off-white to brownish, free, entire to slightly irregular, especially in older ascomata. Proper exciple not visible from above; thalline rim margin to 0.7 mm diam., ±rounded, entire, thick, concolorous with the thallus to off-white or brownish; thalline rim incurved. Proper exciple fused, moderately thin to thick, yellowish brown to pale or dark brownish, usually only indistinctly carbonised, rarely strongly carbonised, sometimes amyloid at the base. Hymenium to c. 250 µm thick, not inspersed, markedly conglutinated; paraphyses ±bent to curly, especially towards the unthickened to slightly thickened tips, parallel to slightly interwoven, unbranched; columellar structures well-developed in mature ascomata, to c. 500 µm wide, entire, rarely complex, usually brown to slightly carbonised, rarely strongly carbonised, usually covered with a ±thick layer of greyish granules. Epihymenium hyaline, with greyish or brownish granules. Asci 4–8-spored; distinct tholus absent; lateral ascus wall rather thick in immature stages, becoming moderately thin. Ascospores transversely septate, oblong to oblong-fusiform, with ±rounded to subacute or acute ends, hyaline, strongly amyloid, 50–120 (–130) × 10–18 µm, with 8–20 (–22) locules; locules ±rounded to slightly angular, oblong to lentiform or ±irregular; end cells similar or subglobose, hemispherical to conical; septa thick, regular; ascospore wall thick, non-halonate at maturity; endospore thick. Pycnidia immersed, with a darkened pore. Conidia fusiform, to 5 × 1 µm.
CHEMISTRY: Thallus K–, C–, P–; containing norisonotatic acid (major), norsubnotatic acid (major to absent).
  Rare on bark in lowland rainforest in north-eastern Qld. Palaeotropical.  
  Mangold et al. (2009)
