The most common types of mold include aspergillus, cladosporium and stachybotrys, also commonly called “black mold”. Mold colors are like a box of crayons in that they come in a variety of hues, from black to white to orange to green.
Aspergillus is a fairly allergenic mold that is commonly found on foods and in home air conditioning systems.
Stachybotrys is sometimes black in color, but not always. Sometimes it can be a darker green color. It is toxic, but it takes a long time to develop and it requires a large, constant water source.
