Toxic black mold is a mold that has been associated with buildings with water damage. The term toxic black mold is somewhat misleading. Mold in itself is not toxic, but molds can produce toxic substances that are called mycotoxins. Black mold is known by the name stachybotrys chartarum or stachybotrys atra. It grows on material that has high cellulose content and a low nitrogen content. These conditions are present in building materials such as gypsum board and fiberboard. Black mold needs a constant supply of moisture to grow. People with weakened immune systems, allergies or asthma have a higher risk of having a reaction to molds.
