Öst. bot. Z., 68: 304, 1919. Basionym: Lecanora liparina Nyl. - Flora, 59: 305, 1876.
Synonyms: Ricasolia cesatii var. olivacea Bagl.; Ricasolia liparina (Nyl.) Flagey; Solenopsora cesatii f. liparina (Nyl.) Clauzade & Cl. Roux
Distribution: N - Lomb (Ravera & al. 2023), Lig (Guttová & al. 2014, 2019). C - Tosc (Guttová & al. 2019, Darmostuk & al. 2022, Lich. Ital. Exs. 75: Isocrono & al. 2023).
Description: Thallus crustose-placodioid, episubstratic, rather loosely attached, forming up to 2.5 cm wide, orbicular rosettes, the central parts sometimes falling off, leaving semicircular arcs of lobes. Lobes 0.3-0.6 mm wide, flat to slightly convex, olivaceous grey or grey-green, with rounded, white-pruinose ends. Apothecia lecanorine, sessile, up to 1  mm across, with a brown, bluish-white-pruinose disc, and a smooth to scabrid, persistent to finally excluded thalline margin. Epithecium brown, granular, the granules not dissolving in K; hymenium colourless, 60-70 µm high; paraphyses coherent, swollen at apices; hypothecium colourless, 80-90 µm high. Asci 8-spored, cylindrical-clavate, with a K/I+ blue outer coat and a K/I+ uniformly blue apical dome, approaching the Catillaria-type Ascospores 1-septate, hyaline, narrowly ellipsoid, straight or slightly curved, 13-16 x 3-4 µm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-, UV-; medulla P+ orange-red. Chemistry: medulla with pannarin and zeorin (both major).
Note: on inclined surfaces of ultrabasic siliceous rocks (e.g. serpentine and basalt), often in fissures, in shaded situations also on vertical faces, mostly in the Mediterranean belt.
