| Thallus immersed to superficial, to c. 150 µm thick, pale yellowish grey to greyish green or pale to medium olive, dull to slightly glossy, smooth, continuous to verruculose, non-rimose. True cortex continuous or discontinuous, to c. 20 µm thick, consisting of periclinal hyphae, occasionally the cortex absent or replaced by a discontinuous protocortex to c. 10 µm thick. Algal layer poorly to well developed, continuous or not; calcium oxalate crystals not seen. Vegetative propagules not seen. Ascomata conspicuous, to c. 0.7 mm diam., ±rounded, initially perithecioid, becoming apothecioid, sessile, solitary to marginally slightly fused, distinctly emergent, subglobular in younger stages, becoming urceolate. Disc not visible from above, occasionally becoming partly visible, flesh-coloured in younger ascomata, becoming pale to dark brownish grey, epruinose. Pores small to moderately broad, rarely gaping, to c. 0.5 mm diam., irregular to stellate; pore margin split; proper exciple not visible from above. Thalline rim margin coarsely cracked to slightly lacerate; thalline rim apically pruinose, off-white, incurved; base smooth, ±cylindrical, conspicuously reddish brown. Proper exciple fused, thick, hyaline to pale yellowish internally, pale yellowish brown marginally, apically sometimes dark brown; internal part of exciple and subhymenium usually slightly to distinctly amyloid. Hymenium to c. 250 (–300) µm thick, conglutinated; paraphyses parallel, with unthickened to slightly thickened tips; lateral paraphyses inconspicuous, to c. 30 µm long. Epihymenium initially hyaline, becoming brownish, without granules, rarely with small sparse crystals. Asci 1 (–2)-spored; tholus initially thick, becoming thin. Ascospores muriform, cylindrical to ±rounded-fusiform, with ±rounded to narrowly rounded ends, initially hyaline, becoming yellowish to pale brown at late maturity, mature ascospores strongly amyloid, 100–210 × 20–55 µm, with numerous locules; locules small, mostly ±rounded to slightly angular, subglobose to irregularly subglobose; ascospore wall initially somewhat thickened, thin at maturity, with a thin halo; endospore thin; transverse septa thin, distinct and ±regular in younger stages, becoming irregular and disappearing, finally the ascospores dissolving internally and generating ascoconidia. Ascoconidia oblong-irregular, to c. 4 × 1 µm. CHEMISTRY: Thallus K–, C–, P–; no secondary compounds detectable by TLC. |

| Occurs in southern Vic. and Tas.; grows over epiphytic bryophytes, rarely on wood or tree bark and on rocks in cool-temperate rainforest, wet-sclerophyll forest, and in coastal, subalpine and alpine heath and moorland, at altitudes of 40–1080 m. Also in southern Africa, India and New Zealand. | ||
