| Thallus squamulose to foliose, lobate, moderately to tightly adnate, forming patches to 8 cm wide; lobes discrete to contiguous to subimbricate, rounded to flabellate or rarely ±truncate, (0.5–) 1–2.5 (–5) mm wide, continuous to subcrustose centrally, plane, becoming undulate to rugulose, ±ascending or rarely inflexed, pale to bright green when fresh and moist, ivory to ash grey to pale green-grey when dry, turning buff to fawn to pink on long storage; outer lobes ±white-pruinose, emaculate or sparingly maculate in densely shaded sites, smooth near margins and lobe apices, but often papillate to short-dactylate laminally with young apothecial initials; margins thickened, slightly recurved, ±paler; cortex pseudo-parenchymatous; medulla white, ±tinged buff or pink on long storage; lower surface ±smooth, arachnoid. Apothecia laminal, often clustered or densely crowded; apothecial initials present as pale hemispherical swellings or papillae in upper cortex which become short-dactylate as stipes elongate, before expanding laterally at apex as disc forms; initially concolorous with upper cortex, soon becoming paler then pinker as disc develops; mature apothecia sessile to shortly stipitate, solitary or clustered and ±confluent, (0.3–) 1–3 (–5) mm wide; disc plane or weakly concave, becoming strongly undulate and irregular to recurved, initially smooth to scabrid to rugulose-scabrid to rarely fissured, ±white-pruinose, ivory to pale brown to mushroom-pink to rose-pink; margin lecideine, buff or ivory to concolorous with thallus on long storage, smooth, eventually crenulate or rugulose. Ascospores at first simple, becoming 1-septate at maturity, ellipsoidal to narrowly ovoid, straight or rarely weakly curved, 12–17.5 (–20.5) × 3–6 (–7) µm (Australian specimens). Pycnidia not seen. CHEMISTRY: Cortex K+ pale yellow, C–, KC–, P+ yellow, UV+ white; apothecia (disc and stipe) K+ yellow then brown, C–, P+ yellow-orange; containing thamnolic acid (major), decarboxythamnolic acid (±trace), 4-O-methylcrypto-chlorophaeic acid (±trace) and 1–4 unknown depsides (±traces). | ||
| Widespread in Tas. and Vic. Also in New Zealand (South Island), including Auckland Is. and Campbell Is. Grows in cool, humid habitats in damp, lightly shaded or sheltered sites on acidic substrata, often on earth banks on sandy, gravelly or peaty soils, organic litter, rarely on wood, over bryophytes and small tussocks, forming extensive patches in favourable sites. | ||
