Ascospores 1-septate, not constricted at septum, ellipsoid to oblong, with more or less equal cells, hyaline, 14-16(-18) x 5-8 µm, surrounded by a rather thick perispore. Pycnidia black. Conidia bacilliform, straight, 3.5-4 x c. 1 µm. Photobiont probably absent. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
