in Pérez-Ortega & Etayo, Lichenologist, 42: 272, 2010. Basionym: Melaspilea canariensis D. Hawksw. - Lichenologist, 14: 84, 1982.

Synonyms: Karschia talcophila var. irregularis Vouaux

Distribution: C - Tosc (TSB 11017, Brackel 2016), Sar (Calatayud & al. 1995, Brackel 2016, Brackel & Berger 2019). S - Si (Santesson 1994, Ottonello & Romano 1997, Ottonello & al. 2011, Brackel 2016).

Description: Thallus not evident, not lichenized, immersed in the thallus of the host lichen. Apothecia black, epruinose, lirelliform to elongate-fusiform, unbranched, 0.3-0.4 x 0.1-0.15 mm, with a slit-like disc and a rather thick proper margin. Proper exciple pseudoparenchymatous, dark brown to black, carbonized, extending below the hymenium in a stalk-like extension, K-, with periphyses developing from the inner excipular layer (visible only in young apothecia); epithecium dark brown, up to 15 μm high; hymenium colourless, 50-75 μm high, I-; paraphyses sparingly branched from the base, 2.5-3.5 μm thick at mid-level, the apical cells up to 4 μm wide; hypothecium dark brown to black. Asci 8-spored, subglobose to shortly clavate, bitunicate, thickened at apex, with a distinct internal apical beak, I- and K/I-. Ascospores 1-septate, slightly constricted at septum, with subequal cells, at first hyaline then turning brown, 14–21 x 6–9.5 μm, smooth-walled. Photobiont absent. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a lichenicolous fungus found on silicicolous pertusarioid species; certainly more widespread in Tyrrhenian Italy.
