Description: Thallus not evident, not lichenized, parasitic on the thalli of Lecanora rupicola s.l. Apothecia black, arranged in dense groups of mostly 5-25, individual apothecia, 0.4-0.7 mm across, semi-immersed, with a widely exposed, rough, dark brown disc, and an often delicately fissured, black proper margin. Exciple 40-60 μm wide, dark brown; epithecium brown, granular, K-; hymenium colourless, 70-80 μm high including the epithecium, the hymenial gel hemiamyloid; paraphysoids branched and anastomosing, 2-3 μm thick, the apical cells 4-6 μm wide; hypothecium dark brown, 70-100 μm high; subhymenium 20-40 μm high. Asci (4-)8-spored, broadly cylindrical to subclavate, the wall I- and K/I- except for an apical ring that is K/I+ blue. Ascospores 3-septate, hyaline, 20-24(-26) x 6-7 μm, , with a thin perispore, the old ones with a brownish verruculose sculpture. Photobiont absent. Spot tests: all negative. Chemistry: no lichen substances.

Note: a holarctic lichenicolous fungus with a wide altitudinal and latitudinal range, growing on the thalli of species of the Lecanora rupicola-complex; certainly neglected and occurring throughout the country wherever the host is present. The record from Friuli by Tretiach & Hafellner 2000) refers to P. protoparmeliae (Hafellner 2009).
