  Thallus to c. 300 µm thick, often bulging and flaking away from the substratum, pale greenish to pale yellowish grey, dull to glossy, smooth or somewhat uneven, ±rugose, continuous or, usually, strongly verruculose, non-rimose. Cortical structures absent or the thallus with a thin discontinuous protocortex to c. 20 µm thick. Algal layer well developed, continuous or discontinuous; calcium oxalate moderately abundant, small, scattered or clustered. Vegetative propagules not seen. Ascomata conspicuous, to c. 1.5 mm diam., ±rounded to slightly irregular, mazaedioid, solitary, strongly emergent, subglobose or becoming urceolate. Pores becoming broad to gaping, to c. 0.8 mm diam., rounded to somewhat elongate, entire to slightly split; apex of the proper exciple often becoming visible from above due to the eroded thalline rim, forming a brownish to reddish brown ring, and/or the proper exciple becoming visible as a distinctly raised slightly incurved to erect corona-like velum, slightly pruinose. Thalline rim margin thick, ±rounded to slightly elongate, becoming distinctly eroded with age, brighter than the thallus; surface like that of the thallus. Proper exciple fused, in older ascomata becoming apically free, thick, hyaline basally, pale orange to orange-brown apically, in upper internal parts often covered by brownish grey granules, non-amyloid. Hymenium not inspersed, distinctly conglutinated; paraphyses thin, slightly interwoven, unbranched, straight to somewhat bent, in mature stages distinctly mazaedioid, the paraphyses disappearing. Asci 8-spored; tholus not visible. Ascospores 2-locular, mostly oblong to fusiform, rarely subglobose, with ±rounded to somewhat subacute ends, brown, non-amyloid, with thickened walls and septum, 6–10 × 4–6 µm; surface becoming distinctly and ±irregularly ornamented; locules usually hemispherical. Pycnidia not seen.
CHEMISTRY: Thallus K+ yellowish to brown, C–, P+ orange; containing stictic acid (major), constictic acid (major), hypostictic acid (minor to trace), a-acetylconstictic acid (trace), hypoconstictic acid (trace).
  Occurs on bark in rainforest in eastern Qld and north-eastern N.S.W., rare in wet-sclerophyll forest, at altitudes of 50–900 m; mainly pantropical.
