Distribution:

Description: Thallus crustose, episubstratic, areolate, pale yellowish green, up to 1 cm across, developing on the thalli of Miriquidica nigroleprosa, the areoles 0.3-0.8 mm wide, smooth, flat to slightly convex, developing from the areoles of the host. Apothecia lecanorine, broadly sessile, 0.3-1.5(-2) mm across, with a flat to convex-uneven, blackish, yellowish-pruinose disc and a smooth to undulate, sulphur yellow thalline margin. Thalline exciple rich in algal cells, corticate, the cortex with dense yellowish crystals visible under polarized light; epithecium grey and N- to dirty green and N+ purple, with crystals; hymenium colourless, c. 65 µm high; paraphyses simple or forked, 1.5-2 µm thick at mid-level, the apical cells swollen; hypothecium colourless. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, of different shapes, broadly ellipsoid to subglobose, 8-14 x 5-8 µm. Photobiont chlorococcoid. Spot tests: thallus K+ faintly yellow, C-, KC-, P-. Chemistry: isousnic acid, zeorin.

Note: a silicicolous species with usually small and scattered individual thalli developing on those of its obligate host, Miriquidica nigroleprosa, with scattered reports from the Alps (outside Italy), where the species is much rarer than its host; to be looked for in the Italian Alps.
