The spores germinate with one or several germ tubes (Bucholtz, 1912; Thaxter, 1922; Walker, 1923). The zygospores are also united into fructifications and arise mostly inside the whitish or yellowish tuberiform hyphal knots up to the size of a hazelnut (Fig. 69, 9), which in some species contain latex organs. At present the youngest known stage of these fructifications consists of a comparatively thick tissue of ramose hyphae which at the periphery are closely intertwined and form a sort of peridium. In the ground tissue, there appear a large number of pairs of copulation branches whose development proceeds approximately simultaneous throughout the fructification. In the only species whose sexual reproduction is well known at present, E. lactiflua (Bucholtz, 1911, 1912), the copulation branches arise mostly.
