Description: Thallus crustose, thinly episubstratic, continuous to rimose-areolate, sometimes reduced to a few small areoles around the apothecia but usually forming larger patches, whitish grey to pale greenish grey, dull, with or without an evident dark prothallus. Apothecia lecanorine or cryptolecanorine, immersed to adnate, 0.2-0.5(-0.7) mm across, with a dark brown to black, epruinose, flat to slightly convex disc, an entire, thin, finally often excluded thalline margin, and a more or less evident parathecial ring. Thalline exciple absent or 50-60 µm wide, ecorticate or with a 10-25(-40) µm thick cortex reacting I+ faintly blue, without crystals; proper exciple thin; epithecium dark brown, K-; hymenium colourless, not inspersed with oil droplets, 60-90 µm high, K/I+ blue; paraphyses 1.5-2.5 µm thick at mid-level, not strongly coherent, the apical cells 3-5(-6) µm wide; hypothecium colourless, (30-)50-80 µm high. Asci 8-spored, narrowly clavate to clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, pigmented, broadly ellipsoid, sometimes slightly curved, (11-)15-17(-21) x (6-)7-8(-9.5) µm, Dirinaria-type, with a warted wall, swollen around the septum after pre-treatment with K, the torus absent or poorly developed, the ontogeny of type B (apical thickenings visible before the insertion of the septum). Pycnidia immersed, black, pyriform. Conidia bacilliform, 3-4(-5) x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a mainly coastal, Mediterranean epiphytic lichen which was overlooked or confused with similar species in the past; mostly Tyrrhenian in Italy. The species is very closely related to the saxicolous R. gennarii (see comment on that species).
