| Australas. Lichenol. 47: 14 (2000). T: Conway State Forest, 16 km E of Proserpine, Qld, 28 June 1986, J.A.Elix 20800 & H.Streimann; holo: CANB. | ||
| Thallus rimose to verruculose or verrucose, yellowish grey to greenish grey, epruinose. Soredia absent. Prothallus blackish brown. Apothecia sessile, 0.5–1.3 mm diam.; disc blackish brown to dark red-brown, epruinose; margin concolorous with the thallus, smooth, entire to verruculose. Cortex hyaline, distinct, inspersed with small crystals, 10–20 µm thick laterally and 15–25 µm thick basally. Amphithecium with large and small crystals; small crystals soluble in KOH (melacarpella-type). Parathecium hyaline, c. 15 µm thick, with numerous small crystals insoluble in KOH. Epihymenium olivaceous brown, c. 10–15 µm thick, without crystals; pigmentation becoming greenish brown in KOH (gangaleoides-type). Hymenium, subhymenium and hypothecium hyaline. Paraphyses sparingly branched and thickened apically. Ascospores ellipsoidal to broadly ellipsoidal, 10.5–14.5 × 6.5–9.0 µm. CHEMISTRY: Thallus and apothecial margin K+ yellow, C–, Pd+ yellow; containing psoromic acid (major), usnic acid (major), atranorin (minor), chloroatranorin (minor) and 2’-O-demethylpsoromic acid (minor). |  |
