. Comparative morphology of Fungi. Fungi. 250 COMPARATIVE MORPHOLOGY OF FUNGI forms a small papilla on the side toward the antheridium (if there are two, toward the nearer) (Fig. 164, 4); the wall dissolves and the nuclei of the antheridium migrate into the ascogonium (Fig. 164, 5). The emptied antheridium collapses and disappears entirely. On account of technical difficulties, the further development of the ascogonium is not yet cleared up. The numerous nuclei migrate from.

(After Killian, 1919.) the tip toward the base and the tip degenerates and disappears; of the ascogonium, there remains only a series of binucleate cells of unknown origin. These develop to ascogenous hyphae which form asci, according to the hook type. The ascospores again infect the ovaries of rye or other grasses in the range of hosts and mummify them. The development of the sexual organs of Claviceps purpurea is remi- niscent of Monascus in the Plectascales. As in the latter, a multinucleate.
