Asci. Subcylindrical, 150-180 (-200) × 25-28 μm, slightly broader below the middle, abruptly contracted below into a very short stipe, 8-spored, with spores arranged in two or three rows. Ascospores. Cylindrical, 48-59 × 9.5-11.5 μm, broadly rounded at the ends, straight or curved, dark brown and opaque at maturity, transversely 3-septate, markedly narrower at each septum; segments easily separable; terminal cells slightly longer than the mid-cells, tapering slightly toward the ends; germ slit oblique to diagonal; gelatinous sheath colourless, broad.
