Description: Thallus crustose, episubstratic, finely rimose-areolate to slightly verrucose, whitish grey to ash-grey, sometimes delimited by a dark prothallus. Areoles flat, ecorticate, smooth, epruinose. Apothecia lecanorine, subimmersed when young, then broadly 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. Thalline exciple pseudocorticate, with numerous algal cells, containing small crystals soluble in K; proper exciple thin, 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 with oil droplets; paraphyses 2-3 µm thick, the apical cells not or slightly thickened, to 3.5 µm wide; hypothecium colourless. Asci 8-spored, 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 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 arounf the ostiole. Conidia thread-like, sometimes 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: a widespread, holarctic silicicolous lichen with a wide altitudinal range, rare only along the Adriatic side of the Peninsula, reaching the Mediterranean belt in Tyrrhenian Italy.
