Bull. Soc. Linn. Normandie, sér. 2, 4: 160, 1870.
Synonyms:
Distribution: C - Tosc, Laz (Gigante & Petriccione 1995), Sar (Monte 1993, Spjut & al. 2020). S - Si (Ottonello & Puntillo 2009, Ottonello & al. 2011).
Description: Thallus fruticose, greenish or yellowish green, somewhat glossy, consisting of 2-5 cm long, (2-)3-7(-12) mm wide, flattened, sometimes slightly canaliculated, simple or sparingly branched, ridged and foveolate laciniae; pseudocyphellae absent or very scarce. Cortex compact, continuous 30-40 µm thick, underlain by longitudinally oriented, 60-230 µm thick chondroid strands; medulla white, rather lax. Apothecia lecanorine, subterminal, 5-6(-8) mm across, with a yellowish green disc and a raised 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, ellipsoid, straight to slightly curved, 10-13.5 x 3.5-6 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC- or KC+ yellow (cortex only), P-, UV-. Chemistry: cortex with usnic acid, medulla with divaricatic acid and terpenoids.
Note: a Mediterranean-Macaronesian lichen found on coastal siliceous rocks, exclusively Tyrrhenian in Italy; it often occurs together with the sibling species R. inaequalis (see Spjut & al. 2020), the two species being difficult to distinguish on the basis of morphological characters only; a revision of Italian material is needed.
