Synonyms: Nesolechia supersparsa (Nyl.) Rehm; Nesolechia vitellinaria var. supersparsa (Nyl.) Keissl.

Distribution: N - Frl (Tretiach & Hafellner 2000, Brackel 2016, Hafellner 2021), TAA (Hafellner 2006, 2021, Brackel 2016), Piem (Brackel 2016), Lig (Herb. von Brackel 502).

Description: Thallus indistinct, not lichenized, immersed in the thallus and apothecia of Lecanora polytropa s.lat. and Rhizoplaca-species. Apothecia lecideine, jet black, sessile, 0.2-0.5 mm across, with a concave to flat disc, and a persistent, raised proper margin. Proper exciple carbonized, green-black or brown-black; epithecium dark blue-green, K+ bright emerald green, N+ red; hymenium colourless; paraphyses simple, conglutinated, 1-2 μm thick at mid-level, the apical cell to 2.5 µm wide; hypothecium colourless to pale brown, K-. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the outer wall very thin, K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid to fusiform with pointed ends, 8.5-13(-14) x 4.5-7 µm. Photobiont absent. Spot tests: all negative. Chemistry: without lichen substances.

Note: a mainly boreal-montane to arctic-alpine, circumpolar lichenicolous fungus, certainly widespread throughout the Alps. Allbeit rarely, the species has been also reported from the Humid Mediterranean ecoregion.
