Ramalina clementeana Llimona & Werner

Acta Phytotaxon. Barcinon., 16: 9, 1975.
Synonyms: Ramalina cribrosa f. fastigiata De Not.
Distribution: C - Tosc, Sar (Spjut & al. 2020).
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 to 6(-8) mm 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. Cortex 2-layered, the outer part paraplectenchymatous, the inner part with chondroid strands; 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. Epithecium pale brownish-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, 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-+ pale yellow, P-, UV-; medulla KC-. Chemistry: cortex with usnic acid, medulla with sekikaic 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.
