Description: Thallus inapparent, developing inside the thalli of Peltigera-species and staining their surface grey-green, not lichenized. Apothecia biatorine, sessile, reddish yellow to blackish, 0.4-0.7 mm across, with an initially flat, soon convex disc, and a thin, soon excluded proper margin. Epithecium yellowish brown; hymenium colourless; paraphyses simple, coherent, the apical cells slightly thickened; hypothecium pale yellowish brown. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass), the wall K/I-, but the thin outer gel K/I+ blue, Bacidia-type. Ascospores (1-)3-5(-7)-septate, hyaline, often curved, 18-40 x 5-8 μm. Photobiont absent. Spot tests: thallus K-, C-, KC-, P-. Chemistry: without lichen substances.
Note: a poorly known lichenicolous fungus growing on the thalli of Peltigera-species, which does not belong to Bacidia s.str.
