| Thallus thin, plane, continuous to rimose-areolate, yellowish grey to greenish grey, epruinose, with coalescent soralia soon covering most of the thallus. Soredia farinose to granular, whitish to whitish grey, 15–30 µm diam. Prothallus not visible. Apothecia immersed when immature, becoming sessile, 0.2–0.6 mm diam.; disc pale to dark red-brown, epruinose; margin concolorous with the thallus, thick, ±verrucose to verruculose. Cortex hyaline, inspersed with small crystals, 15–20 µm thick laterally and c. 20 µm thick basally, sometimes replaced by soredia. Amphithecium with large crystals insoluble in KOH (pulicaris-type). Parathecium hyaline, 15–25 µm thick, with numerous small crystals soluble in KOH. Epihymenium reddish brown, K–, without crystals (glabrata-type), c. 10–12 µm thick. Hymenium, subhymenium and hypothecium hyaline. Paraphyses sparingly branched and thickened apically. Ascospores ellipsoidal, 12.0–15.5 × 6.0–8.5 µm. CHEMISTRY: Thallus and apothecial margin K+ yellow, C– or C+ faint yellowish orange, Pd+ pale orange; containing atranorin (major), chodatin (major), demethylchodatin (major), zeorin (major), chloroatranorin (minor), 3-O-methylthiophanic acid (minor), thiophanic acid (minor) and traces of unknown xanthones. |  |
