Involucrellum dark brown, mingled with bark cells; exciple thin, pale brown; hamathecium of branched pseudoparaphyses anastomosing above the asci, c. 1 μm thick, not inspersed with oil droplets; hymenial gel non-amylod. Asci 2-6-spored, cylindrical to clavate, thick-walled, the inner wall thickened towards apices, with a shallow, broad ocular chamber.
