Distribution: N - Ven, TAA (Spitale & Nascimbene 2012), Lomb (Knudsen & Kocourková 2008), Piem, Emil (Brackel 2016, Fariselli & al. 2020). C - Tosc, Abr, Mol. S - Pugl, Cal (Puntillo 1996).

Description: Thallus crustose, not evident, developing inside the apothecia of Protoblastenia incrustans. Apothecia lecideine, black, round, dispersed, superficial, 0.15-0.25 mm across, the disc mostly flat, with carbonized umbos or ridges or without carbonization, reddish when wet, the margin rugulose-furrowed. Excipulum carbonized in outer part, hyaline to black within, 40-100 μm thick, continuous with the hypothecium; epithecium 10-25 μm high, dark brown; hymenium colourless, 80-120 μm high; paraphyses coherent (becoming lax in K), simple to sparingly branched, regularly septate, 2-3 μm thick, the apical cells unexpanded; hypothecium 100-150 μm thick, continuous with vegetative hyphae. Asci 100-200-spored, strongly thickened at apex, the apical dome K/I-, the outer coat K/I+ blue. Ascospores 1-celled, hyaline, ellipsoid to broadly ellipsoid, 4.5-6 x 2-3 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a widespread lichenicolous fungus, doubtfully lichenised, most frequent on calcareous rocks in sunny habitats in upland areas; growing in the apothecia of Protoblastenia-species.
