Apothecia sessile, 0.4–1.0 mm diam.; disc orange-brown to pale red-brown, epruinose; margin concolorous with the thallus, thin, smooth, entire to verruculose. Cortex hyaline, indistinct, inspersed with small crystals, 10–20 µm thick laterally and basally. Amphithecium with large crystals insoluble in KOH (pulicaris-type). Parathecium hyaline, c. 15 µm thick, with numerous small crystals insoluble in KOH. Epihymenium reddish brown, 10–15 µm thick, with numerous small crystals; pigmentation and crystals soluble in KOH (pulicaris-type). Hymenium, subhymenium and hypothecium hyaline. Paraphyses sparingly branched and thickened apically. Ascospores ellipsoidal to broadly ellipsoidal, 9.5–12.5 × 5.5–7.5 µm. CHEMISTRY: Thallus and apothecial margin K+ yellowish or K–, C–, Pd+ orange; containing psoromic acid (major), usnic acid (major), atranorin (minor), chloroatranorin (minor), 2’-O-demethylpsoromic acid (minor) and unidentified terpenoids. |  |
