Distribution:

Description: Thallus crustose, poorly evident, completely immersed in the thalli of Miriquidica nigroleprosa. Apothecia zeorine, sparse, 0.2-0.5 mm across, with a rust-red to orange-red, flat to convex, rough disc, and a slightly raised, sometimes greyish-orange, finally often excluded proper margin. Proper exciple relatively thick, with algae in lower part, I+ distinctly blue; epithecium brownish orange, K+ red, C+ purple (section!); hymenium colourless, 50-70 µm high; paraphyses simple or sparingly branched, the apical cells only slightly swollen; hypothecium colourless. Asci (6-)8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, broadly ellipsoid, 10-12 x 5-6 µm, the equatorial thickening (“septum”) 2.5-4 µm thick, or subglobose, c. 10 µm wide, the equatorial thickening 2.5-3.5 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ purple-red, C+ purple (the last reaction best observed in thick sections under the microscope). Chemistry: apothecia with chlorinated anthraquinones.

Note: exclusively parasite on thalli of the silicicolous Miriquidica nigroleprosa, usually from the high montane to the lower alpine belt; widespread in the European parts of the Holarctic, including the Alps, but rare; not reported from Italy, to be looked for in the Alps.
