The different types of it are hidden and overlooked. Here’s our guide that will help identify any hidden mildew present. Read on!


Penicillium is a common type of mold in homes and is known for causing allergies and asthma attacks. This type comes in many colors, usually from white to green to blue-gray. The majority of Penicillium is found in damp or water-damaged areas, such as basements, bathrooms, and kitchens.

This has many health benefits, as some types are used to produce antibiotics like penicillin. It can also be found on roof shingles, wood, cardboard, and even in shower grout.


Chaetomium is one prominent strain found in damp, wet places. This type is known for having a musty, earthy smell and is typically gray, white, or black in color. It can grow on paper, cardboard, insulation, fiberboard, drywall, and other materials.

In some cases, when the material has been wet for a long period of time, Chaetomium can even appear as a cotton-like texture on the surface. If your home has been exposed to moisture, it is important to have a mold removal or inspection to ensure that you do not have this kind of problem.


Stachybotrys is one of the more infamous types, known as black mold due to its distinct black color. This form of mold is known to produce toxins into the air which can cause serious respiratory issues and other ailments. Identifying the type of mold is important to understand the severity of the issue and the resulting health risks.


Aspergillus is an airborne fungus that is able to be found in some environments in the form of spores. This is usually found in damp, warm, and humid areas such as bathrooms, laundry rooms, and other areas that may have experienced flooding, or poor ventilation.

While aspergillus may not harm healthy individuals, those who suffer from allergies and respiratory problems such as asthma may experience flu-like symptoms from exposure to it.


Cladosporium is a greenish-black mold that is found both indoors and outdoors. It is particularly well-suited to grow on painted or wooden surfaces. It’s also found in HVAC systems, carpets, and on wallpaper or other paper products.

Cladosporium produces a wooly or cottony texture and can produce hay-like or musty odors. This particular species of mold is not particularly toxic, but it is an allergen and can still be harmful to those with weakened immune systems.
