Each category includes many species of mold, and they have a wide variety of harmful qualities. Symptoms range from allergy type reactions to deadly illnesses. All five of these categories can grow indoors and be found in our homes.


Stachybotrys is an intensely dangerous fungus, also known as black mold. Mold species under this genus produce mycotoxins wherever they are disturbed, which can cause serious infections. They usually grow on materials that contain cellulose and that have remained damp for a long period of time. Surfaces include cardboard and gypsum board, ceiling tiles, and wood etc.

Stachybotrys has also been linked to severe illness in young infants. Those people with compromised immune systems, small children, and the elderly are highly susceptible to illness when they encounter this type of mold.


About 200 known species of Penicillium are known to exist in the air or soil. Their purpose is to cause food and other perishable goods to spoil, and their presence usually indicates high moisture levels in the environment. Indoors, they will cling to various damp surfaces, such as walls and wallpapers, floors, and carpets. Colors range from blue and yellow to green and white.

These mold families have been connected to illnesses such as nail fungus, asthma.


Cladosporium is a very common mold and is one that falls into the most dangerous mold category. This genus comes in an array of colors from green, brown, gray, or black colors and is comprised of around 40 different species. Common gathering spots include painted walls, wood, carpets etc.

Chronic cases of Cladosporium can produce pulmonary edema and emphysema.


Fusarium comes to life even at lower temperatures and is most often spotted growing on water-damaged carpeting and fabrics. Its prolonged presence can cause mild allergic reactions, asthma, and severe respiratory conditions. It will appear orange in color.
