Synonyms: Lecanora rupicola f. sorediata (Flot.) Zahlbr.; Lecanora rupicola subsp. rupicola var. efflorens Leuckert & Poelt

Distribution: N - Frl, Piem (TSB 35252), Emil (Fariselli & al. 2020). C - Sar. S - Si.

Description: Thallus crustose, episubstratic, finely rimose-areolate to slightly verrucose, whitish grey to ash-grey, sometimes delimited by a dark prothallus, sorediate. Areoles flat, ecorticate, smooth, epruinose, bearing scattered, flat to convex, bluish-grey soralia. Apothecia almost always present, lecanorine, subimmersed when young, then sessile, (0.5-)1-2(-3) mm across, with a brown, grey brown or black (in forms parasitized by Arthonia varians), but heavily bluish-white-pruinose, usually flat disc, and a thin, persistent, smooth, sometimes flexuose thalline margin; proper margin not visible macroscopically. Amphithecium pseudocorticate, with numerous algal cells, containing small crystals soluble in K; parathecium colourless, lacking crystals; epithecium almost colourless to yellowish or greenish brown, the pigment dissolving in K, with a layer of crystals dissolving in K and reacting C+ yellow; hymenium colourless, 75-95 µm high, not inspersed; paraphyses 2-3 µm thick, the apical cells not or slightly thickened, to 3.5 µm wide; hypothecium colourless Asci 8-spored, elongate-clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 9-15 x 5-8 µm, the wall <1 µm thick. Pycnidia immersed, the wall colourless except around the ostiole. Conidia thread-like, cometimes curved, 14-25 µm long. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC-, P- or P+ pale yellow, UV+ white; apothecial disc C+ bright lemon-yellow, P-. Chemistry: thallus with atranorin (major), roccellic acid (major), chloroatranorin and eugenitol (minor); pruina of apothecia with sordidone (major).

Note: optimum in somehow more shaded-humid situations than the typical variety; probably more widespread in the Alps.
