What is Stachybotrys chartarum?
Stachybotrys chartarum (also known as Stachybotrys atra) is a type of mold that has been associated with health effects in people. It is a greenish-black mold that can grow on materials with a high cellulose content - such as drywall sheet rock, dropped ceiling tiles, and wood - that become chronically moist or water-damaged, due to excessive humidity, water leaks, condensation, or flooding.
How can you tell if Stachybotrys chartarum is present in your home?
Many molds are black in appearance but are not Stachybotrys. For example, the black mold commonly found between bathroom tiles is not Stachybotrys. Stachybotrys can be positively identified only by specially trained professionals (e.g., mycologists) through a microscopic exam.
