The scientific name for black bread mold is Rhizopus stolonifer. It is also referred as R. stolonifer. Label the following on the figure below: hyphae, zygosporangium w/zygospores, suspensor cells, ploidy. Black mold lives by dissolving the bread and absorb the nutrition. The other kind of spores is called sporangiospores. Observe black bread mold, Rhizopus, (sexual or with zygospores). Black bread mold is also called ergot. In asexual reproduction, the mold makes spores inside a sporangium. Zygospores are fungal seeds that are made from sexual reproduction, a notable feature of bread mold's group, the Zygomycota. The surrounding condition in which the mold resides, is the factor that causes either type of reproduction by the mold. Zygomycota: The Conjugated Fungi. Also known as black bread mold.
