Black molds are from the species Stachybotrys chartarum and can usually be found growing on and consuming materials made from the cell walls of green plants, such as wood and cardboard. They are particularly common in materials that have undergone water damage. These molds aren’t themselves toxic but can produce more mycotoxins than most other types of mold. In the past, black mold was thought to cause pulmonary hemorrhage and death in infants, but that link has since been disproven by the U.S. Centers for Disease Control.
