Mold is a type of fungus with spores and hair-like bodies of individual mold colonies which are too small for us to see without a microscope. Molds are decomposers of dead organic material, such as wood; plants; and leaves. When there is a large amount of mold growing on a surface, it will appear to have a black or green color. The color of mold can be influenced by the age of the colony and nutrient source the mold feeds on. When mold grows behind vinyl wallpaper, you will notice pink or purple splotches.
