Black bread mold (Rhizopus stolonifer) is a widely distributed thread-like mucoralean mold. Commonly found on bread surfaces, it takes food and nutrients from the bread and causes damage to the surface where it lives.
Asexual spores are formed within pinhead-like sporangia, which break to release the spores when mature. Germination of these spores forms the haploid hyphae of a new mycelium. R. stolonifer grows rapidly at temperatures between 15 and 30°C.
