The ascogenous hyphae springing from the ascogonium are coenocytic, , they contain a number of dicaryons (Fig. 221, 1), and develop by repeated forking, more or less vertically toward the top of the future fructification. Subsequently they divide by septa so that in the neighborhood of the ascogonium, the cells contain 2 to 8 dicaryons and farther away only one (Fig. 221, 2). A cell with only one dicaryon puts forth a lateral process whereby the nuclei become.
