Rhizopus stolonifer sexual reproduction occurs only when opposite mating come in contact thus, successful results develop the formation of zygospores at the point of contact and subsequently germinates to form sporangiophore that contains both + and – sporangium spores. Two varieties produced during reproduction either straight sporangiophores or curved sporangiophores.
Rhizopus stolonifer has visible black spores that emerge on damp leathers, bread and decaying fruits. It is a common disease of papayas during storage andtransportation wherein the packed boxes will collapse due to the watery leakage from the fruits. This fungus grows out in the cuticle and multiplies rapidly to adjacent fruits and form coarse gray hairy mycelia black mass of sporangia.
Rhizopus stolonifer is proficient in utilizing lesion as a path of entry since it is an airborne and incapable of penetrating through uninjured surfaces wherein punctured wound is more susceptible than bruises or abrasions. It is usually found in compost, soil and other decaying plant matter in which incident causing this fungus increases during rainy seasons.
