1 Two of the better-known toxic molds include Stachybotrys chartarum (black mold), which can cause everything from headaches to cancer, and Aspergillus, which can cause severe lung infections, or progress to whole-body infections.2  Mold is particularly dangerous for infants and children.he color of a mold generally has to do with the spores it produces, and has no bearing on whether it is dangerous or not. There are some white molds that grow on walls and other surfaces that can be just as bad as the harmful black molds.. Mycotoxin poisoning by Stachybotrys is referred to as stachybotryotoxicosis.
