Fr.; Pannaria lepidiota f. sorediosa Vain.; Pannaria lepidiota var. imbricata Vain.; Pannaria lepidiota var. tristis Th. Fr.; Parmeliella lepidiota (Sommerf.) Vain.; Parmeliella praetermissa (Nyl.)

Distribution: N - Frl (Tretiach & Hafellner 2000), Ven (Nascimbene & Caniglia 2003c, Nascimbene 2005c, 2008c, Nascimbene & Marini 2007), TAA (Nascimbene & al. 2006, Thor & Nascimbene 2007, Nascimbene 2008b), Lomb (Etayo & Navarro-Rosinés 2008), Piem (Isocrono & al. 2004), VA (Nascimbene & al. 2021), Lig (TSB 33471). C - Tosc (Nascimbene & al. 2021).
Description: Thallus squamulose, heteromerous, c. 300 µm thick, brown to dark brown with a bluish tinge, forming continuous, thick crusts several cm in diam., usually without hypothallus. Squamules 2(-3) mm long, up to c. 1.5 mm broad, round to weakly elongate, incised, flattened, contiguous or mostly imbricate, the margins white-felted due to accumulation of terpenoid crystals, with erect, finger-like lobules looking like isidia. Upper cortex sclerenchymatous, (20-)30-50 µm thick; lower surface ecorticate, felted. Apothecia rare, cryptolecanorine, to 1.5 mm across, with a brown, usually convex disc, a dark proper margin, and an often excluded, granulose thalline margin. Hymenium colourless, 100-120 µm thick, I+ blue-green rapidly turning red-brown; paraphyses simple, slightly thickened above; hypothecium colourless. Asci 8-spored, clavate to subcylindrical, with a I+ blue tholus and an internal, more intensely I+ blue structure. Ascospores 1-celled, hyaline, ovoid to broadly ellipsoid, often with a single, large oil droplet, 18-22 x 9-11 µm, with a thick, smooth epispore. Photobiont cyanobacterial (Nostoc, the cells in clusters). Pycnidia wart-like. Conidia bacilliform. Spot tests: Thallus K-, C-, KC-, P-, UV-. Chemistry: unidentified fatty acids and triterpenoids.
Note: an arctic-alpine to boreal-montane, circumpolar lichen found on calciferous soil, mosses and plant debris, with optimum near and above treeline.
Growth form: Squamulose
Substrata: soil, terricolous mosses, and plant debris
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
