Stachybotrys chartarum (often referred to as ‘Stachybotrys atra’ or ‘black mold’) is typically greenish-black in color, and found on surfaces in areas where high levels of moisture is present - black mold pictures can be seen below. Common causes of high moisture levels include: excessive humidity, water leakage/damage, condensation, and floods.
In addition to moisture, black mold requires a nutrient (food source) for significant growth to take place. A familiar nutrient that black mold thrives on is cellulose, a widespread organic compound found just about anywhere. Examples in a home or building include: drywall, ceiling tile, various paper-based products, wood, upholstery, carpeting, and different fabrics.
Because many species of mold can be black in color, it is not recommended or necessary to “test” mold; rather, any and all mold found in a home should be treated as potentially dangerous and discarded, cleaned, or handled by a professional. Here are some of the most common areas in which black mold can be found, including actual pictures of black mold on each:
