| Nuovo Giorn. Bot. Ital. 11: 75 (1879). T: Cala d'Ostia, Pula, Sardinia, Italy, Mar. 1867, G.Canepa; lecto: H, fide H.T.Lumbsch, J. Hattori Bot. Lab. 77: 106 (1994). | ||
| Thallus thin to thick, plane to slightly bullate, dispersed-verrucose to verruculose, yellowish white to whitish grey, epruinose. Soredia absent. Prothallus not visible. Apothecia sessile, 0.4–1.0 mm diam.; disc pale yellow to pale red-brown or grey-brown, not or slightly whitish grey-pruinose; margin concolorous with the thallus, thin, entire, ±verrucose to verruculose. Cortex hyaline, ±gelatinous, inspersed with small crystals, distinct, 10–15 µm thick laterally and 20–25 (–35) µm thick basally. Amphithecium with large crystals insoluble in KOH (pulicaris-type). Parathecium hyaline, without crystals, 10–15 µm thick. Epihymenium dark grey-brown to dark red-brown, c. 10–15 µm thick, with numerous small crystals (chlarotera-type); pigmentation rapidly dissolving in KOH. Hymenium and subhymenium hyaline. Hypothecium yellowish to hyaline. Paraphyses sparingly branched and thickened apically. Ascospores ellipsoidal, 10.0–13.5 × 5.0–7.0 µm. CHEMISTRY: Thallus and apothecial margin K+ yellow, C+ red, Pd+ pale orange; containing atranorin (major), 3,5-dichloro-2’-O-methylanziaic acid (major), chloroatranorin (minor), 5-chloro-2’-O-methylanziaic acid (minor), 3,5-dichloro-2’-O-methylnorhyperlatolic acid (minor) and 3,5-dichloro-2’-O-methylstenosporic acid (minor). |
