in A.Mangold, J.A.Elix & H.T.Lumbsch, Fl. Australia 57: 656 (2009)

T: Black Mountain Rd, 33 km WNW of Kuranda, Qld, alt. 800 m, on bark in rainforest logging area, 20 July 1983, M.E.Hale 832139; holo: US.

 
     
  Thallus endophloeodal to epiphloeodal, to c. 200 µm thick, yellowish brown, ±glossy, smooth, continuous to slightly verrucose, rimose. True cortex continuous, to 50 µm thick, yellowish, formed by irregular hyphae, often with substratum inclusions. Algal layer moderately well developed, ±continuous; calcium oxalate crystals abundant, mostly small and scattered, rarely clustered. Vegetative propagules not seen. Ascomata ±inconspicuous, to c. 0.4 mm diam., ±rounded (usually appearing irregular due to thalline rim structure), apothecioid to indistinctly chroodiscoid in older stages, erumpent, solitary to marginally fused and somewhat clustered, immersed. Disc rarely becoming partly visible from above, whitish, epruinose. Pores formed by the thalline rim margin, to c. 0.2 mm diam., irregular, split and lobed to slightly layered, in more open ascomata the proper exciple becoming visible as a dark brown to blackish internal layer, externally pale greyish or paler than or concolorous with the thallus; thalline rim incurved, occasionally erect. Proper exciple fused, moderately thick, yellowish to yellowish brown internally, dark brown or carbonised towards the margins, with substratum inclusions, non-amyloid. Hymenium to c. 90 µm thick, not inspersed, moderately conglutinated; paraphyses straight to slightly bent, parallel to slightly interwoven, unbranched, with moderately thickened tips; columellar structures absent. Epihymenium hyaline, with greyish granules. Asci 8-spored; tholus thick. Ascospores submuriform to muriform, ellipsoidal, fusiform or somewhat clavate, with rounded to subacute ends, hyaline, non-amyloid, 15–25 × 7–10 µm, with 6–8 × 1–3 locules; locules ±rounded to slightly angular, mostly irregular; end cells hemispherical to conical; transverse septa distinct; ascospore wall initially thick, becoming thin, non-halonate; endospore thick. Pycnidia not seen.
CHEMISTRY: Thallus K–, C–, P–; no compounds detectable by TLC.
     
  Known only from the type locality in north-eastern Qld; grows on bark in a rainforest at c. 800 m.
