The plasmodium is multinucleate and diploid. When food supplies are limited or the environment dries, the plasmodia cease their streaming and may form thick-walled structures called sclerotia (singular, sclerotium) in which the protoplasm can withstand adverse environmental conditions. Growth is resumed with the return of more favorable circumstances. Both asexual and sexual reproduction occurs, but the initiation clues to each process remain obscure.
