 Description: Ascomata scattered to densely aggregated, immersed, becoming erumpent, globose to subglobose, 600-750 μm high including the beak, 725-750 μm wide, covered with brown mycelia. Beak short, 150-250 μm high, 275-300 μm wide. The ascomatal wall 35-56 μm thick is composed of pseudoparenchymatous cells forming a textura angularis. Pseudoparaphyses filiform, septate, colourless, mucose, diffluent. Asci numerous, stalked, bitunicate, 8-spored, 112-165 × 12-13 μm. Ascospores filiform, 6-11-(mostly 7-) transversely septate, straight to slightly curved, pale brown to brown, smooth, not or slightly constricted at some septa, 70-90 × 3-4.5 μm, without mucilaginous sheath, terminal mucilaginous appendages of characteristic nodose swellings.

 Note: This species is very close to Ophiobolus. mayorii E. Müller (1952) in ascospore sep-tation and size. The ascospores in O. mayorii are 8-10-septate, 70-85 × 2.5-3 μm with the 4th to 6th cell often slightly nodose. It can be easily separated from other Ophiobolus species (Müller, 1952; Shoemaker, 1976) by its ascospore size by the number of septa in the ascospores.
