Synonyms: Ramalina mediterranea H. Magn.; Ramalina pollinaria var. pulvinata Anzi; Ramalina pulvinata (Anzi) Nyl.
Distribution: N - Lig (Jatta 1909-1911). C - Tosc, Laz (Gigante & Petriccione 1995), Sar (Monte 1993, Neuwirth 2018, Spjut & al. 2020). S - Cal (Puntillo 1996), Si (Ottonello & Romano 1997, Ottonello & al. 2011).
Description: Thallus fruticose, yellowish green to greenish grey, shrubby, forming small, 1-3 cm wide cushions. Laciniae simple or branched only at base, crowded, erect, flattened and strap-shaped, 0.5-3(-4) mm wide and 0.5-3 cm long, foveolate-reticulate, sometimes with a few pseudocyphellae, the apices more or less broadened. Medulla white, solid. Apothecia absent to numerous, lecanorine, mostly subapical, concolorous with thallus, with a concave, greenish, often pruinose disc and a smooth to slightly rugose thalline margin. Epithecium pale olive; hymenium and hypothecium colourless; paraphyses thick-walled, richly branched in upper part. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass) never penetrating through the entire d-layer, the wall K/I-, but the thin outer gel K/I+ blue, Bacidia-type. Ascospores 1-septate, hyaline, slightly curved, 9-16 x 4-6 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC- or KC+ yellowish, P-. Chemistry: cortex with usnic acid.
Note: a mainly Mediterranean species found on coastal siliceous rocks; one of the most common epilithic species of the genus along the Mediterranean coasts, with a Tyrrhenian distribution in Italy. It belongs to a complex in need of revision.
