Distribution:

Description: Thallus crustose, very thinly episubstratic, smooth, grey-green, sometimes poorly evident. Apothecia round, 0.8-0.9 mm across, strongly constricted at base, with a brown, initially urceolate, finally flat to slightly convex disc and a thin proper margin. Proper exciple of a loose network of thin, anastomosing hyphae embedded in a gelatinous matrix; epithecium brownish; hymenium colourless, 80-90 µm high, I-; paraphyses richly branched and anastomosing in upper part, c. 1 µm thick; hypothecium colourless. Asci 4-6-spored, up to 70 µm long, cylindrical-clavate, thin-walled, apically thickened, the contents K/I+ reddish. Ascospores submuriform, with (4-)5(-6) transverse septa and a single longitudinal septum, constricted at septa, hyaline, elongate-fusiform, 15-25 x 5-8 µm, with a poorly evident gelatinous perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on soil and plant debris over calciferous schists; so far only known from the Eastern Alps (Tyrol, Austria), near treeline; to be looked for in the Italian Alps.
