Epithecium brown; hymenium colourless, amyloid; paraphyses coherent; hypothecium pale brown. Asci 8-spored, clavate. Ascospores 1-septate, not constricted at septum, brown, 18-20 x 12-13(-15) µm. Photobiont chlorococcoid. Spot tests: Thallus K-, C-, KC-, P-. Chemistry: unknown, probably without lichen substances.
