Altitudinal distribution: alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)
Note: this long-forgotten and poorly understood species, often wrongly attributed to Baglietto alone, is characterised by a white, subleprose, rugulose-subgranulose, spreading thallus, small, subsessile, plane to convex, black apothecia with a thin to poorly evident proper margin (resembling those of Lecidella wulfenii), a yellowish brown epihymenium, a colourless hypothecium, adglutinate paraphyses, 8-spored, clavate asci, and large, fusiform, 3-7-septate ascospores which are 5-6 times as long as wide; known only from the type collection, on Silene acaulis in the alpine belt; the type material, most probably in MOD, would be worthy of further study.
