Description: Thallus squamulose, red to bright brownish red, often coarsely white-pruinose especially at margins, the squamules (2-)3-5(-6) mm broad, more or less rounded, concave to convex, usually with upturned, often crenulate, whitish edges, contiguous to scattered, smooth to fissured; lower surface whitish, attached by rhizohyphae. Upper cortex up to 80-120 μm thick, of thin-walled hyphae with round lumina; lower cortex absent or poorly developed. Apothecia biatorine, sessile, mostly marginal, up to 1.5-2 mm across, with a dark brown to usually black, sometimes white- or yellowish-pruinose, convex, smooth disc and an indistinct proper margin. Epithecium reddish brown, containing orange crystals dissolving in K, K+ purple, N-; hymenium colourless, amyloid; paraphyses stout, strongly coherent, simple or sparingly branched and anastomosing, 4-6 μm thick, the apical cell slightly swollen; hypothecium brownish, with crystals of calcium oxalate. 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, P- or P+ orange. Chemistry: chemotype 1) without lichen substances (the most widespread in Cental and northern Europe), chemotype 2) medulla with norstictic acid (mainly Mediterranean), chemotype 3) medulla with hyposalazinic and hypostictic acid (rare, known from Austria, Hungary and Spain); epithecium with anthraquinones, mainly parietin.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). P. decipiens is a complex of several lineages apparently deserving species recognition (Leavitt & al. 2018), one of which includes P. saviczii, which is nested within P.
decipiens, hence the latter is paraphyletic in its current concept. The records of P. crenata from Sardinia and Sicily by Jatta (1909-1911) most probably refer to P. decipiens.
