How To Id the Different Kinds of Mold in Your Home

March 21, 2022

Mold is a moisture-loving fungus that comes in many types and thrives in temperatures between 60 and 80 degrees. Some mold is helpful, like the kind that breaks down dead leaves and wood. But the kind of mold that grows in your home is not only unsightly, but it can also be dangerous to your health.

Three main types of mold can grow in your home: black mold, white mold, and mildew. The different mold types in your home have unique characteristics and require a different approach to removal.

Black Mold

The most common type of black mold is Stachybotrys chartarum, which is often found in homes with water damage. Stachybotrys chartarum is a greenish-black color, and you may see it on items such as paper or fiberboard. Black mold is especially dangerous, as it can cause serious respiratory problems such as coughing, wheezing, and difficulty breathing. The appearance of black mold is usually a greenish-black or black slimy substance.

White Mold

White mold is not as dangerous as black mold, but it can still cause respiratory problems if you are exposed to it for a long time. It looks powdery and forms imperfect circles. You will often see it on furniture or floors.


Mildew is a type of white mold that grows on damp surfaces such as areas in bathrooms and basements. Mildew is not dangerous, but it can be tough to remove. If you have mildew in your home, you should clean the affected area with a mixture of bleach and water.


Alternaria is a type of mold found in damp areas such as showers, basements or anywhere with water damage. It has a "hairy" appearance and can cause itchy eyes, coughing and sneezing.


Acremonium is a type of white mold that can be found on food and in the air. This type of mold is not dangerous, but it can cause allergies in some people.


Cladosporium is green or brown mold found in carpets, wood floors, cabinets, and walls.


Fusarium is a type of mold found in water-damaged materials such as wallpaper, carpet, and insulation. It can cause skin infections.


Penicillium is a type of white mold that can be found on food and in the air. When fruit begins to turn moldy, it is usually because of this type of mold.

If you are having trouble identifying the type of mold in your home, you can contact a mold remediation contractor for help. These professionals have experience identifying different types of mold and know the best way to remove them. By removing the mold from your home, you can protect your health and improve the appearance of your home.
