Distribution: N - Ven (Nimis 1994, Knudsen & al. 2023), Lomb, Piem (Isocrono & al. 2004, Knudsen & al. 2023), Emil (Tretiach & al. 2008, Fariselli & al. 2020).
Description: Thallus crustose, endosubstratic and poorly evident. Apothecia lecideine, slightly immersed to subsessile, 1-2.5 mm across, mostly 0.2-0.4 mm high, broadly attached when small, eventually forming a narrow mycelial base, with a brown-red to black (dark brown-red when moist), epruinose or blue-pruinose, flat to slightly convex disc, and a thin, soon excluded proper margin. Proper exciple 90-150 μm wide, of c. 1 µm wide. radiating hyphae with swollen and dark brown tips, pale brown to colourless within, the darker rim 60-100 μm wide, not clearly delimited from the paler medullary part; epithecium reddish brown, up to 10 µm high; hymenium colourless, (100-)140-150 µm high, K/I+ blue; paraphyses c. 2 µm thick at mid-level, coherent, simple to sparingly branched, regularly septate, not capitate; subhymenium 40-60 μm high, K/I+ dark blue; hypothecium up to 60 μm high, inspersed with substrate crystals, continuous with attaching hyphae. Asci 100-200-spored, cylindrical-clavate, strongly thickened at apex, the apical dome K/I-, the outer coat K/I+ blue, 100-120 x 10-20 μm, Ascospores 1-celled, hyaline, ellipsoid to narrowly ellipsoid, 3-5 x 1-1.5(-2) µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a widespread species, known from (Austria, Czech Republic, Germany, Italy, Norway, western Russia near Finland, and Switzerland, most common on dolomitic pebbles above treeline, probably more widespread in the Alps. The record from Umbria by Panfili (2007), being dubious, is not accepted here.
