Prothallus whitish grey or not visible. Apothecia immersed to sessile when immature, becoming constricted at the base, 0.4–1.5 mm diam.; disc yellowish brown, heavily bluish grey-pruinose; margin concolorous with the thallus, thin to thick, entire, flexuose. Cortex inspersed with small crystals that are insoluble in KOH, distinct, gelatinous, 15–25 µm thick laterally and 25–50 µm thick basally. Amphithecium with small crystals soluble in KOH. Parathecium with small crystals, c. 15 µm thick. Epihymenium olivaceous brown, c. 10 µm thick, with crystals soluble in KOH. Hymenium, subhymenium and hypothecium hyaline. Paraphyses sparingly branched and thickened apically. Ascospores ellipsoidal, 9.5–13.5 × 5.0–7.0 µm. CHEMISTRY: Thallus and apothecial margin K+ yellow, C+ orange, Pd+ pale orange; apothecial disc C+ orange; containing atranorin (major), roccellic acid (major), sordidone (major), chloroatranorin (minor) and eugenitol (minor). |  |
