A lichen resembling members of the genera Lecidea and Miriquidica. Diagnostic features are the relatively thick, light grey to yellowish thallus composed of flat to convex areoles that contain atranorin, bourgeanic acid and sometimes also usnic acid (cortex K+ yellow, medulla K+ yellow/orange, Pd+ orange).
This predominantly arctic-alpine species grows on exposed acidic silicates. Within central Europe it is more abundant in the Alps, elsewhere it is a rare lichen. There is a number of historical records from the Czech Republic (see the Catalogue by Vězda & Liška 1999). Recently, the species has been confirmed only from the Krkonoše Mountains.taxonomic classification:
