Acta Phytotaxon. Barcinon., 16: 9, 1975.
Synonyms: Ramalina cribrosa f. fastigiata De Not.
Distribution: C - Tosc, Sar.
Description: Thallus fruticose, yellowish green to grey-green, forming dense orbicular pillows, consisting of subcylindrical, rigid, swollen, mostly simple, up to 4(-5) cm long and 0.6 cm wide laciniae originating from a common holdfast; upper surface smooth, with a few, punctiform to ellipsoid, whitish pseudocyphellae, often becoming longitudinally cracked-fenestrate in old samples. Medulla white, hollow. Apothecia lecanorine, subterminal, short-stalked, to 6(-8) mm wide, with a cream-coloured, pruinose disc and a thin, raised, smooth, often undulate thalline margin. Asci 8-spored, clavate to subcylindrical, Bacidia-type. Ascospores 1-septate, hyaline, ellipsoid, straight to slightly curved, 10-15 x 4-6 μm. Pycnidia black, immersed, mainly apical. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-+ yellowish, P-, UV-; medulla KC-. Chemistry: cortex with usnic acid.
Note: a Mediterranean-Macaronesian lichen found on coastal siliceous rocks, only in areas with frequent humid, maritime winds; related to R. pusilla, differing in the ecology and in some minor morphological characters, but also in the absence of salazinic acid.
