Black mold is generally thought by the general public to be toxigenic. But what is black mold? There are a number of molds that grow indoors and they appear black. Some of these are not even known to produce any significant amounts of toxins. Stachybotrys chartarum, which is incorrectly referred to as black mold is known to produce toxins. However, even the toxigenic molds do not produce toxins all the time. Several factors including substrate composition, water activity, pH and temperature influence production of mycotoxins.

It is difficult to know whether a toxigenic mold has produced toxins or not unless the material on which the mold is growing is tested for mycotoxins.
