Black mold is not necessarily toxic. Most mold ranges in color and many types are black. Black mold is different from other types of mold because, by nature, it has a black pigment. It is allergenic and some types are toxic but not all types. Cladosporium is the most common black mold that triggers asthma and allergy symptoms. Stachybotrys chartarum is a black toxic mold that is usually found in attics. This mold is dangerous to inhale or ingest.

Which Is Worse Black Mold or Green Mold?

Green mold is an umbrella term referring to different fungi species that have different green hues. You may have seen green mold in food like bread and fruits. The most common are Penicillium, Aspergillus, and Cladosporium. Both black and green mold can be dangerous and even toxic to inhale or ingest.
