Distribution: N - TAA (Nascimbene & al. 2007b, 2022, Jabłońska 2009), Lomb, Emil (Tretiach & al. 2008, Fariselli & al. 2020). C - Tosc (Tretiach & al. 2008), Sar (Neuwirth 2018).
Description: Thallus crustose, episubstratic, continuous to rimose-verruculose, very well developed, thick, forming large patches, white-grey to cream-coloured, sorediate, often delimited by a black prothallus. Soralia irregular in outline, often formed along cracks, whitish to grey-white; soralia coarsely granular to almost digitiform. Medulla white, I-. Apothecia rather frequent also in sorediate forms, lecideine, semi-immersed to sessile and constricted at base, black, 0.8-2(-2.5) mm across, with a flat to moderately convex, pruinose disc, and a thick, raised, usually epruinose, often flexuose proper margin. Proper exciple dark in outer part, colourless within, the hyphae 2-4 μm thick; epithecium olive-brown; hymenium colourless, 150-190 μm high; paraphyses coherent, branched and anastomosing, slightly swollen at tips; hypothecium dark brown. Asci 8-spored, elongate-clavate, with a thin, outer amyloid layer and a thickened tholus penetrated by a pore, the sides of which stain I/KI+ deep blue, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid, 15-25 x (5-)7-10(-12) μm. Photobiont chlorococcoid. Spot tests: thallus and soralia K-, C-, KC-, P-. Chemistry: without lichen substances, or with glaucophaeic acid, 2'-O-methylsuperphyllinic acid or confluentic acid, methy-2-O-methylmicrophyllinate.Note: a mainly mild-temperate species found on siliceous, often metamorphic rocks in sheltered situations, such as in forests and deep gorges, along rivers and creeks, or on pebbles on moist ground.
