Suppl. Fl. Lappon.: 96, 1826.
Synonyms: Lecanora intricata var. leptacina (Sommerf.) Stizenb.
Distribution: N - Piem (Isocrono & al. 2004).
Description: Thallus crustose, episubstratic, yellowish to yellowish green, granulose or areolate, the areoles convex, scattered to mostly contiguous, forming an uneven compact crust, often slightly elongate at margins, sometimes surrounded by a dark prothallus. Apothecia lecanorine, rounded, semi-immersed to subsessile, (0.5-)0.8-1.2(-1.5) mm across, with an often faintly white-bluish-pruinose, olive-green disc turning blackish with age, and a persistent, smooth smooth to finally crenulate-undulate thalline margin. Epithecium yellowish brown, K+ blue-green; hymenium colourless, 55-85 μm high; paraphyses sparingly branched and anastomosing, 1.3-2 μm thick at mid-level, the apical cells up 3-4(-5) μm wide; hypothecium colourless. Asci 8-spored, broadly clavate, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, (9-)10-14(-15) x (4.5-)5-8(-9) μm, the wall c. 1 μm thick. Pycnidia dark. Conidia thread-like, up to 20 μm long. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly yellow, C-, KC-, P- or rarely P+ faintly yellow, UV-. Chemistry: psoromic and 2'-0-demethylpsoromic acid, traces of atranorin.Note: a probably circumpolar, arctic-alpine lichen found on mosses (e-g- Andreaea, Grimmia) and plant debris in sites with a long snow-covering period above treeline, in areas with siliceous substrata.
