Description: Thallus crustose, episubstratic, rather thick, rimose-areolate or areolate, pale yellowish grey to (rarely) dark grey, the areoles up to 0.3-0.6 mm wide, flat, with a slightly verrucose surface. Apothecia at first lecanorine and more or less immersed in thallus, becoming pseudolecanorine and adnate, 0.4-1 mm across, with a black, usually flat disc, an entire, finally often excluded thalline margin, and a dark brown to black, persistent parathecial ring. Thalline exciple 60-100 µm wide laterally, the cortex 10-15 µm wide, sometimes becoming pigmented, dark brown or aeruginose in outer part, the pigmented parts N+ and K+ red; crystals present in cortex, absent in medulla; proper exciple colourless or more often blue-green to black-brown in upper and outer parts, the pigmented parts reacting K+ and N+ red; epithecium reddish brown, with a finely granulose epipsamma; hymenium colourless, not inspersed with oil droplets, (90-)100-115 µm high; paraphyses 1.5-2(-3) µm wide at mid-level, the apical cells 3-6 µm wide; hypothecium colourless, up to 200 µm high. Asci 8-spored, 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, brown, broadly ellipsoid, (19-)22-27(-30) x (10-)12-14(-16) μm, Mischoblastia-type, often swollen at septum at maturity, the torus poorly developed, the walls lightly pigmented and not ornamented, with an ontogeny of type A (apical wall thickening after septum formation). Pycnidia dark, immersed. Conidia bacilliform, 3-5 µm x c. 1 μm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC-, P+ faintly yellow. Chemistry: cortex with atranorin.

Note: a species known from North America, Asia, Central Europe, the Mediterranean Region, Morocco and the Canary Islands, found on basic siliceous rocks, such as magmatite; closely related to R. oxydata. For further details see Sheard (2010).
