Description: Thallus crustose, episubstratic, pale grey, diffuse, consisting of goniocysts- or soredia-like, diffuse 60-250 μm thick granules, the peripheral parts sometimes with ill-defined, subeffigurate and subsquamulose areoles, the terminal lobules 60–250 μm wide. Perithecia black, 0.2-0.4 mm across, semi-immersed in thallus (which often forms a collar around them), the ostiolar region distinctly depressed. Exciple reddish brown but irregularly pigmented; involucrellum absent; hamathecium of periphyses, interascal filaments absent; hymenial gel I+ red (I+ yellowish or blue at low concentrations of I), K/I+ blue. Asci 8-spored, clavate, short-stalked, with delicate walls, K/I-. Ascospores (3-)5-7-septate, hyaline, ellipsoid-fusiform, (23-)27-37(-43) x (5-)6-8(-9) μm. Photobiont chlorococcoid. Spot tests: thallus K-, KC-, C-, P-, UV+ orange-pink after heating. Chemistry: two unidentified terpenoids (without zeorin).Note: on bark and mossy siliceous rocks. Orange (2022) described N. acroglypta as occurring over rock and N. chlorococca over bark, but all three Norwegian specimens of N. acroglypta included in his phylogeny occurred over bark (Svensson & al. 2024), so that the difference in substrate does not appear to be diagnostic. The species is known from Austria, and should be looked for also in Italy.
