Several types of mold can grow on drywall, each with distinct characteristics: Black mold (Stachybotrys chartarum): Often found in areas with constant moisture.

Black Mould on walls (Stachybotrys chartarum, Aspergillus niger or others) is often a sign of a serious problem in your home that needs to be thoroughly investigated. It is often caused by excess condensation, usually as a result of a lack of ventilation in the home that results in high humidity levels.
