Distribution:

Description: Thallus crustose, thin and filmy, hardly visible, brownish, minutely granular but without goniocysts. Apothecia short-lived, without a proper margin, single or paired, 0.3-1 mm across, turbinate when young, stalked when mature (but appearing sessile when crowded amongst goniocysts), the stipe 40-80 µm thick, composed of subparallel hyphae, the disc becoming convex to globose, pale flesh-coloured to orange-brown, without a proper margin. Proper exciple absent; hymenium lacking gelatine, consisting of asci which are sometimes intermixed with a few, slender, branched and anastomosing paraphyses confined to the lower part of hymenium, not entwining the asci. Asci 8-spored, cylindrical, thick-walled, with a thick I+ blue apex (except for an apical pore), 50-60 x 9-12 μm. Ascospores 1-septate,with slightly unequal cells, hyaline, narrowly ellipsoid, (12-)13-15(-16) x 3-4 μm, with rounded ends and a smooth wall. Photobiont chlorococcoid (Leptosira). Spot tests: all negative. Chemistry: without lichen substances.

Note: on mosses and liverworts in montane regions of Central Europe and the Tropics, mostly in humid forests, but reaching also the alpine belt. Rare, but known from several stations in the Alps; to be looked for in Italy.
