A common mold that grows on bread looks like white cottony fuzz at first. If you watch that mold for a few days, it will turn black. The tiny black dots are its spores, which can grow to produce more mold.
Bread kept in plastic packets gets moldy easily as the evaporated water provides a good environment for the spores to grow. Yeast reproduces because of these spores. The growth of such microorganisms is quite prominent because of the colored spots like green, white, yellow, gray, or black.
Rhizopus stolonifer is commonly known as black bread mold.
