Description: Thallus crustose, episubstratic, areolate, whitish-grey-pruinose to grey, greenish when wet, sorediate, forming patches up to 1.5 cm in diam. Areoles angular, 0.3-0.8(-1) mm wide, flat or with raised margins, with marginal, dark grey to green-grey soralia erupting from the lower surface, the old areoles sometimes completely sorediate and confluent, forming a dark grey sorediate crust. True cortex not developed or rarely present, up to 10 µm thick, formed of 1-2 rows of paraplectenchymatous, thin-walled cells; phenocortex usually present, c. 20–40 µm thick; epinecral layer c. 5-10 µm thick, often with a white, crystalline pruina; medulla inconspicuous, prosoplectenchymatous, loose. Apothecia zeorine, 0.3-0.8(-1.1) mm across, with an initially urceolate, later flat, brown to black disc, and a whitish , smooth to crenulated margin. Thalline exciple ecorticate; proper exciple of thin-walled, elongated cells, grey-brown (Sedifolia-grey pigment) in upper part, the pigmented parts K+ violet; epithecium greyish, usually covered by crystals, K+ weakly violet; hymenium colourless, 70-110 µm high; paraphyses c. 1.5-3.5 µm thick, the apical cells usually inflated, up to 5.5 µm wide; hypothecium colourless, paraplectenchymatous, 40-230 µm high in central part. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, (13-)15-20 x (5-) 7-9 µm, the equatorial thickening (“septum”) occupying c. half of spore length. Pycnidial wall slightly greyish (Sedifolia-grey) around the ostiole. Conidia broadly ellipsoid to subglobose. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; soralia, upper part of the proper exciple (strong reactions), epithecium, and pycnidia walls (weak reactions) K+ violet. Chemistry: Sedifolia-grey pigment in the K+ violet-reacting parts.
Note: a species described from Eastern Europe, where it usually grows on concrete, mostly along water channels in dry areas, usually 1-3 m above water level; the species should be looked for also in Italy.
