T: Mungo Brush Camping Area, Myall Lakes Natl Park, N.S.W., A.Mangold 23s; holo: CANB; iso: F, NSW.

  Thallus endophloeodal to epiphloeodal, to c. 300 µm thick, pale greenish grey to pale olive, glossy, smooth, verrucose to verruculose, ±strongly rimose to areolate. True cortex continuous, to c. 35 µm thick, consisting of periclinal hyphae. Algal layer well developed, continuous; calcium oxalate crystals abundant, large, clustered, rarely forming columns. Vegetative propagules not seen. Ascomata ±inconspicuous, to c. 0.9 mm diam., ±rounded to slightly irregular, perithecioid, solitary, immersed to moderately raised, then verrucose-hemispherical. Disc and proper exciple not visible from above. Thalline rim margin small, to c. 0.2 mm diam., ±rounded, entire, rarely slightly split, often funnel-shaped, brighter than the thallus to off-white; thalline rim incurved. Proper exciple fused, moderately thin to thick, dark brown to carbonised, non-amyloid. Hymenium to c. 700 µm thick, not inspersed, strongly conglutinated; paraphyses thin, bent to slightly curly distally, slightly interwoven, unbranched to slightly branched towards margins and columella, with moderately thickened tips; columellar structures well developed, to c. 300 µm wide, entire, conical with a tapered tip, carbonised, uncovered. Epihymenium indistinct. Asci 1-spored; tholus initially moderately thick, thin when mature. Ascospores muriform, oblong-fusiform, ±bent, with narrowly rounded to subacute ends, hyaline to yellowish or becoming pale brownish, strongly amyloid, 300–500 (–550) × 25–50 µm, with numerous locules; locules ±rounded to ±angular, subglobose to irregular, in younger stages subdivided by several distinct thicker irregular transverse septa, otherwise transverse septa indistinct and irregular; ascospore wall thin to thick, thinly halonate; endospore thin to thick. Pycnidia not seen.
CHEMISTRY:Thallus K–, C–, P–; no compounds detectable by TLC.
  Corticolousin rainforest and wet-sclerophyll forest in eastern Qld and north-eastern N.S.W., from sea level to 1000 m; also in New Caledonia.
