4 Common Types of Mold that are Dangerous to Human Health

Mold is a form of fungus that often grows in wooden houses when the conditions are damp and favorable enough for their growth, but wood isn’t the only surface on which it grows. In fact, under the right circumstances, mold can easily grow on concrete and even metal. As they often make the air around them toxigenic and allergenic by releasing spores, it’s imperative that you take the necessary precautions to get rid of a growth as soon as you detect it. In case you are not sure about the types of mold that are commonly found in homes, offices and other buildings within the United States, take a look at the following.brick-wall-3194516_960_720

Acremonium comes in orange, pink, grey and white variants and all forms of this mold is toxicogenic and carcinogenic by default. The mycotoxins they release into the air can cause bone marrow disease, mycetoma and cancers in various organs within the body. You will likely find these in or near cooling coils, humidifiers, window sealants and drain pans, accompanied by another even more dangerous fungus, known as strachybotrys.


This mold is basically what you see in pictures most of the time because alternaria is the most common form of mold found in the US and in most other countries that are particularly susceptible to mold infestations. This species has a velvety appearance and feel (you should not be touching them), along with bottle green or brown hyphae (looks like hair). You will likely find these in the dampest of places such as under the sink or bathtub, within the shower or even the walls if they are damp enough. While they are not as toxic as some of their brethren, alternaria is still a potent allergen and can make life very hard for asthma patients.


Common in old houses and buildings with water damage, chaetomium can cause skin infections, nail infections, allergies and may even start producing mycotoxins if allowed to stay unhindered long enough for them to turn black. Roofs, basements, water pipes and just about any other place with moisture or water damage is perfect for the initially white, cottonlike fungus to grow.


Unlike a lot of the other fungi, fusarium doesn’t need warm and damp places to breed because they can easily withstand cold and harsh conditions, just like cladosporium; another common fungus immune to colder climates, but not nearly as dangerous. Fusarium is not only an allergenic, but also a toxicogenic fungus. This species of mold can cause dermatitis and various forms of skin, sinus and lung allergies, but that’s not the main concern here. The pink/red/white fungus can even cause the people in proximity to develop brain tumors, nerve damage, internal bleeding and bone disease. Fusarium is partial to carpets, wallpaper and any other fabric that you may have lying around for a long time.

While these are only four, there are multiple other types of fungus out there that can potentially kill us. Examples include mucor, ulocladium and of course, the infamous stachybotrys or black mold, which grows in conjunction with a lot of the less harmful molds.

The bottom line is, if you see mold growing in any part of your home or office, don’t try to clean it off on your own, just maintain your distance and call for professional help. Thankfully, mold remediation Minneapolis is not really a problem because there are expert services like ServiceMaster Restore here that can take care of any mold related issues immediately and efficiently. It is important to remember that while you may only see a little bit of the mold coming out of a crack, it is more than likely that the growth has already spread deeper than you can see.
