Ascus maturation and spore discharge are described for the marine and brackish-water fungus Leptosphaeria discors. The mature ascus is bitunicate. Circumscissile rupture of the ectoascus occurs to free the extensile endoascus. A thimble-shaped cap is cast off from the ectoascus and the endoascus elongates through the subsequent fissure. Spore discharge is simultaneous rather than successive, and occurs normally in seawater.
