This structure (multinucleate) is called gynophore (Lotsy, 1907). It is abjointed from the hypha and subsequently develops to numerous helical ascogonia which in turn are abjointed. In their vicinity, from the same original hypha are one or more branches (androphores) forking to form antheridia which subsequently coil helically around the ascogonia. Thus there are formed structures shown in a simple case in Fig. 223, 4. The antheridial branch (approximately quinque nucleate) remains un- divided ; the female branch is septate and divides into a short bi- to tri- nucleate, apical trichogyne, and a longer, about quinque nucleate, ascogonium. Hereupon, apparently as in Pyronema confluens, after the.
