Description: Thallus squamulose, red to bright brownish red, often coarsely white-pruinose especially at the margin. Squamules (2-)3-6 mm broad, more or less rounded, concave to convex, usually with upturned, crenulate, whitish edges, contiguous to scattered, smooth to fissured. Lower surface whitish, ecorticate. Upper cortex 80-120 μm thick, of thin-walled hyphae with round lumina; lower cortex absent or poorly developed. Apothecia lecideine, sessile, mostly marginal, up to 1.5-2 mm across, with a dark brown to usually black, sometimes white-pruinose, convex, smooth disc, and an indistinct proper margin. Epithecium reddish brown, K+ red; paraphyses coherent, anastomosing; hypothecium brownish. Asci 8-spored, elongate-clavate, with a thin, outer amyloid layer and a thickened tholus penetrated by a tube, the sides of which stain I/KI+ deep blue, without an ocular chamber, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid, 11-18(-20.5) x (4-)6-8 μm, thin-walled. Pycnidia dark, laminal, immersed. Conidia bacilliform, 6-7 x 1 μm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-, UV-; medulla K- or K+ yellow turning red. Chemistry: without lichen substances or medulla with norstictic acid (especially in Mediterranean samples); epithecium with anthraquinones.Note: a widespread holarctic species with a broad altitudinal and latitudinal range, found on bare calciferous soil, especially in dry grasslands; rare only in areas with intensive grazing, high trampling, and intense disturbance. The wide ecological amplitude could be due to the capacity of this species to associate with several different species of Trebouxia and Asterochloris (Ruprecht & al. 2016). The records of P. crenata from Sardinia and Sicily by Jatta (1909-1911) most probably refer to this species.
