Description: Thallus not lichenized, the hyphae growing inside the thalli of calcicolous Circinaria-species. Apothecia lecideine, 0.2-0.6 mm across, often grouped and confluent, black, usually epruinose, with a flat to slightly convex disc and a thin, finally sometimes excluded proper margin. Proper exciple brownish black, usually with a green tinge, K-, N+ violet, lacking crystals; epithecium dark green, K-, N+ purple-red with the formation of blue crystals ; hymenium colourless, 35-40(-50) µm high; paraphyses simple, not coherent, 1.7-2 μm thick, the apical cells swollen, up to 5 μm wide; hypothecium reddish brown, K+ purple, N+ orange-red. Asci 8-spored, clavate, surrounded by a gelatinous I+ blue coat, with a well-developed I+ blue tholus with a I+ darker blue tube and a well-developed ocular chamber, Bacidia-type. Ascospores 1-septate, hyaline, ellipsoid, (9-)10-14 x 3.5-4.5(-5.5) µm. Photobiont absent. Spot tests: thallus K-, C-, KC-, P-. Chemistry: probably without lichen substances.
Note: a mainly Mediterranean(-Atlantic) lichenicolous fungus found on hard limestone, on the thalli of Circinaria calcarea, more rarely of C. coronata and Protoparmeliopsis versicolor.
