Distribution:

Description: Thallus crustose, pale brown, areolate, poorly delimited, 2-3 cm wide, without a distinct prothallus, parasitic on the thalli of Lecanora umbrosa. Areoles rounded to subangular, convex, 0.3-0.5(-1.2) mm wide, with a 30-60 µm thick phenocortex. Apothecia cryptolecanorine, dispersed to aggregate, adnate, 0.5-1 mm across, with a soon convex to globose, reddish brown, shiny disc, and a very soon excluded thalline margin. Exciple of conglutinated, branched hyphae, not forming a cupula below the hypothecium; epithecium diffuse pale brown, 15-18 µm high; hymenium colourless, c. 70 µm high; paraphyses coherent, branched in upper part, rarely anastomosing; hypothecium colourless, 40-60 µm high. Asci 8-spored, clavate, approaching the Lecanora-type, with a well-developed amyloid tholus and a distinct, non-amyloid axial mass. Ascospores 1-celled (overmature spores rarely 1-septate), hyaline, oblong-ellipsoid to ovoid, 10-15 x 5-8 µm. Pycnidia dark, semi-immersed. Conidia straight, 7-12 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.

Note: extremely rare on shaded, steeply inclined to vertical faces of basic siliceous rocks with a low content in calcium (e.g. amphibolite); only known from the Eastern Alps (Austria) and the Karakorum: to be looked for in the Italian Alps.
