In asexual reproduction, special non-motile hyphae called sporangiophores produce sporangia that form in an upright fashion. The sporangia at the tips of the upright hyphae develop as bulbous black portions. Branching structures, called rhizoids, anchor the fungus into the substrate, releasing digestive enzymes and absorbing nutrients for the fungus. When conditions are good the sporangia, containing numerous haploid spores of which are produced through mitosis, release the spores into the surrounding atmosphere. These spores then may land on a moist surface and the life cycle repeats.
