Description: Thallus crustose to subleprose, very thinly episubstratic, dull grass-green, granular, entirely consisting of minute goniocysts spreading diffusely over the substrate, surrounded by colourless hyphae with very small papillae. Perithecia c. 0.1 mm across, projecting, yellowish- to orange-brown when dry, almost translucent and colourless when wet. Exciple 10-12 μm thick, colourless or yellowish, of periclinally arranged hyphae; involucrellum absent; hamathecium of branched periphyses measuring c. 15 x 2 μm, interascal filaments absent; hymenial gel I+ red, K/I+ blue. Asci 8-spored, fissitunicate, clavate-cylindrical to pyriform, thickened at apex when young, K/I-, 45-50 x 10-15 μm. Ascospores at first simple, but soon becoming 1-3-septate, hyaline, narrowly ellipsoid, more or less attenuate at the lower end, 12-20 x 3.5-4.5 μm, without a perispore. Photobiont chlorococcoid, the cells 8-12 μm wide. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.Note: optimum on the bark of Sambucus in shaded-humid situations. It is included as “Critically Endangered” in the Italian red list of epiphytic lichens (Nascimbene & al. 2013c).
