Brown mold, which consists of multiple species of mold, is common in places that are prone to or have serious water damage or leak issues.

You probably have brown mold if you notice dark, discolored areas on your walls, especially if they appear in groupings.

It is also known to discharge observable spores into the air as well as having a strong musty odor.

Types of Brown Mold

Brown mold is extremely hard to recognize solely from visual inspection since it frequently combines different mold species. The following are some of the most typical kinds of brown mold seen in properties:


Also known as pipe cleaner slime, chocolate tube slime mold, tree hair, and hairy brown slime mold. These names come from the way it creates strands that resemble hair or feathers. Bathrooms and rotting wood are two examples of moist environments where it thrives swiftly.


This type of mold usually looks dark brown or black, produces dark spores, and thrives in moist environments or places that have suffered water damage. It is well-known that if left untreated, it can result in allergies, asthma, and, in extreme circumstances, even lethal infections.


This type of mold, which frequently develops as a result of water damage, needs much more moisture to survive than other types of mold.  It can cause allergic reactions, illnesses, and even death.

Aureobasidium Pullulans

This type, which ranges in color from pink to black, is frequently found growing in a variety of environments and has a history of causing infections. It is especially dangerous to people who have underlying respiratory conditions.


It is frequently found in wood and might look brown or black. It is a typical cause of wood rot.

Pithomyces Chartarum

It is a common, rapidly growing mold that can survive in a range of environmental circumstances and temperatures. It creates mycotoxins, which can be harmful to both humans and animals.


This type of mold has filaments and is dark brown or black in appearance. It can harm your skin, brain, and eyes. This mold also affects crops, which is dangerous.


Individuals are extremely prone to this kind of mold. Chaetomium has approximately a hundred different species. It usually grows outside on soil and the remains of dead plants. It might be dark brown or olive green. Your skin and nails might get severely infected by this mold.


This type of mold is dark brown or olive-black. This is soft, velvety, and occasionally covered in wool, which might make your asthma and fever worse.

Stachybotrys Chartarum

Although it is known as black mold, it can also occasionally be dark brown. Compared to other varieties of mold, it has the strongest odor, which is unpleasant due to its thick mustiness. It grows in moist environments, such as bathrooms or areas that have recently seen a flood. Sometimes it also appears powdery and slimy. Your allergic reactions could get worse; it primarily affects animals but can potentially seriously harm humans.

The color of mold may vary based on the age of the colony, the surface it is growing on, and the presence of other contaminants, therefore it’s important to remember that color is not certainly a trustworthy indicator of mold type. To determine the type of mold, it is important to have a mold professional inspect and test the mold.
