Taxon, 63: 740, 2014. Basionym: Opegrapha mougeotii A. Massal. - Mem. Lichenogr.: 103, 1853.
Synonyms: Opegrapha leightonii Cromb. ex Nyl.; Opegrapha mougeotii var. pisana Bagl. ex Jatta; Opegrapha mougeotii var. tiburtina Jatta
Description: Thallus crustose, endosubstratic to thinly episubstratic, smooth to finely cracked, very thin (<0.2 mm), white to cream-coloured. Apothecia lirelliform, black, epruinose, dispersed or grouped, sessile, simple or rarely sparingly branched, to 1.5(-2.5) mm long, 0.2-0.5 mm wide, with pointed ends and a slit-like, rarely finally exposed disc. Proper exciple carbonized, extending below the hymenium, 30-50 µm thick laterally, K-; epithecium brown, 1.2-1.5 μm high, K-; hymenium colourless, 45-70(-120) µm high, I+ red; hypothecium black, carbonized, 20-40(-70) μm high. Asci 8-spored, cylindrical-clavate, the inner layer of endoascus amyloid in upper part, with a I+ blue ring visible around a small ocular chamber, Varia-type. Ascospores 5-7(-8)-septate, hyaline, finally sometimes brownish, spindle-shaped, straight or slightly curved, (19-)25-35(-55) x (4-)6-8(-10) µm, the central cell larger than the others, with a 0.8-2 µm thick perispore. Pycnidia rather frequent, black. Conidia of two types: a) bacilliform, 5-10 x 0.5-1 µm, b) ellipsoid, 3-5 x c. 1.5 µm. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
