Exciple dark throughout; hymenial gel I+ red (I+ blue at very low concentrations of iodine), K/I+ blue; hymenial algae almost isodiametrical, 3-4 μm wide; hamathecium of periphyses and periphysoids, interascal filaments absent. Asci 4–8-spored, clavate, the wall thickened above, with an ocular chamber, after dehiscence with a delicate extruded endotunica, I-, K/I-. Ascospores muriform, hyaline, finally sometimes light pink-brown, ellipsoid, (18-)25-60 x (11-)14-25 μm. Pycnidia black, immersed in the thallus. Conidia bacilliform.
