1. Fungi have complex life cycles consisting of asexual and sexual reproductive phases. Here we examine the life cycle of the black bread mold, Rhizopus stolonifer. The black speckles that Rhizopus produces on bread are capsules, called sporangia, that the fungus produces through asexual reproduction. 2 The fungus consists of a network of filaments, called hyphae, that penetrate the bread and absorb nutrients. During asexual reproduction, spore-filled sporangia develop at the tops of stalklike h
