Mold Types Found In Homes

There are a wide variety of molds you may find in your home. Below are some of the more common and dangerous molds you should keep an eye out for!

Alternaria: Alternaria is often found outdoors, but can be found indoors in places where moisture is prevalent like showers and near leaky pipes. It can also be seen in places that have experienced water damage. However, it can spread easily from those places and infect nearby buildings. Exposure to alternaria can potentially cause allergic reactions and asthma attacks.

Aspergillus: Aspergillus is commonly found indoors and can cause a variety of health issues. Aside from normal conditions like allergic reactions and respiratory infections, it can also cause hypersensitivity pneumonitis, which causes lung inflammation.

Aureobasidium: Aureobasidium is typically found outdoors and is denoted by its pink and black color. Like many molds, it can still be found indoors where moisture is common and is often on damp window frames. Aureobasidium is a common allergen.

Botrytis: Botrytis is found indoors where humidity is high and can cause allergic reactions and asthma attacks.

Chaetomium: Chaetomium is commonly found on drywall, carpets, and window frames that have sustained water damage. It can be identified by its musty odor.

Cladosporium: Cladosporium is a genus of fungi including some of the most common indoor and outdoor molds and can potentially cause allergies and asthma attacks. It can be found in many different climates and typically grows on carpets and woods.

Fusarium: Fusarium is similar to cladosporium in that it can be also be found in lower temperatures where other molds might not be able to grow. It’s often found growing on water-damaged carpeting and other fabrics. It causes allergic reactions, asthma, and respiratory infections.

Penicillium: A collection of fungi that is common in house dust and grows on wallpaper and wallpaper glue, wallpaper glue, fabrics, wall board, moist chipboards, and behind paint. It can be denoted by its blue or green colors, and can cause allergic reactions, chronic sinus infections, and inflammation of the lungs.

Stachybotrys chartarum: Also known as black mold or toxic black mold, is a mold that is black in color and can be very hazardous if left unchecked. Possible symptoms to prolonged black mold exposure are allergic reactions, breathing problems, chronic sinus infections, asthma attacks, fatigue, and depression.

Sepula lacrymans: A yellow mold that is commonly found on wood. It is responsible for “dry rot”, wood decay that occurs despite a lack of moisture.

Trichoderma: Often found on wet surfaces, the effects of trichoderma are similar to the effects of stachybotyrs chartarum, making it highly dangerous.

Ulocliadium: Another mold that is a common allergen. Uloclaidum is only found in homes suffering extensive water damage as it requires a large amount of water to grow.

Efflorescence: Salt deposits often found in basements and commonly confused for mold.
