General Description

 Ascomata. Perithecial scattered or loosely aggregated, immersed when young, becoming nearly superficial when old, subglobose to nearly pyriform, 100-200 × 90-120 μm, smooth, bare, dark brown to nearly black; neck small, papilliform, smooth, bare, black; peridium thin, membranaceous. Asci. Short and broad, more or less cylindrical, (80-) 90-100 × 13-18 μm, broadly rounded above, broadest part below the middle, abruptly contracted below into a very short stipe, 8-spored, with spores obliquely arranged in two or three rows. Ascospores. Cylindrical, 28-32 (-34) × 5-6 μm, broadly rounded at the ends, straight or curved, ranging from colourless when young through yellowish brown to dark brown and opaque, transversely 3-septate; markedly narrower at each septum; segments readily separable; cells nearly equal in size; terminal cells very slightly narrower toward the ends; germ slit nearly parallel with a kink near the middle; gelatinous sheath colourless, narrow. Paraphyses. Scanty, filiform, septate, equalling the asci and mixed with them.
