in Hafellner & al., Mitt. naturwiss. Ver. Steiermark, 134: 95, 2005. Basionym: Lecanora admontensis Zahlbr. - Ann. Mycol., 1: 357, 1903.
Synonyms: Lecanora luridescens Zahlbr.
Description: Thallus crustose-placodioid, episubstratic, chalky white or yellowish-white in peripheral parts, thick, forming up to 20 cm wide rosettes, the central parts areolate-verrucose and often dying off, leaving concentric rings of contiguous, 2-3 mm long, c. 0.5 mm wide, flat or slightly convex lobes. Cortex 50-70 µm thick, densely inspersed with transparent crystals soluble in HCl and small yellow-brown granules; medulla white, filled with crystals soluble in HCl. Apothecia lecanorine, 0.5-1 mm across, usually crowded, rounded to irregular in outline, with a brown to blackish brown, usually flat disc and an entire to crenulate, persistent thalline margin. Epithecium brownish; hymenium colourless, c. 60 µm high, inspersed with oil droplets in upper part, I+ blue; paraphyses mostly simple; hypothecium colourless. Asci 8-spored, elongate-clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 8-12 x 5-8 µm. Photobiont chlorococcoid. Spot tests: cortex K- or K+ very pale yellow, C-, KC- or KC+ faintly yellow, P-, medulla P+ yellow. Chemistry: cortex with usnic acid, medulla with psoromic acid.
