The splitting up of the irregular blocks of protoplasm, which have the nuclei irregularly distributed through them, proceeds until the protoplasmic blocks arebinucleated, and before this the nuclei are seen in various stages of division which proceeds irregularly in Didymium, while in Fuligo the division of the nuclei is simultaneous in a particular spore sack. The plasma membranes of the capillitial openings are the source of cleavage furrows to even a greater degree than the original surface plasma membrane of the spore sack as a whole. In Fuligo in the final stages of spore formation the spore plasm is condensed about the nuclei, but in Didymium, the ultimate.
