As we all know, all molds are not the same. It is estimated that there are more than 100,000 types of molds. Some of them are beneficial for humans, others are harmful, while a few are toxic.

No matter what type of mold it is, they are unwelcoming for every home. It is one of the common causes of allergies in people. Moreover, it can cause serious damages to the structure of your house, if left unnoticed for long.

Therefore, it is best to learn about identifying the type of mold. So, in this blog, we are going to discuss the common types of mold.

Common Types of Mold:

The Common Types of Mold Found Inside Homes

1. Acremonium Mold

It is actually a genus of fungus which consists of more than 100 species. This type of mold evolves in its appearance over time. It is found inside homes, especially near humidifiers, cooling colds, window sealants, etc.

Acremonium mold can grow well if the humidity levels are high inside the room. It can even develop in food and starts as a small moist mold which will turn into a fine powdery substance over time. Most often it is seen in shades of pink, grey, orange or even off-white.

It is a slow-growing mold that is prolific and must be removed. It causes a stench smell, which is one way to identify its presence. Acremonium is toxic mold and exposure to this species of fungus is very dangerous.

Being a carcinogen, it has the ability to destroy the immune system, internal organs, bone marrow, and brain. If you doubt the presence of acremonium inside your house, the next step is to hire professional mold removal specialists.

Do not try to remove it yourself as it can put your health at risk.

2. Aureobasidium 

If you find a pink, brown or black color behind the wallpaper or wooden surfaces, it could be this type of mold. Aureobasidium is another common allergenic mold found inside homes. It can grow in soil, forest soils, plants, fruit, wood, etc.

Inside the homes, this type of mold grows on surfaces that are mostly damp; such as bathrooms, kitchens, shower curtains, window sills, etc. This type of mold can get dark with time. Hence, it is sometimes referred to as black mold by media. However, it is not scientifically called black mold.

Exposure to Aureobasidium causes various health issues in people. Infection of eyes, throat, skin, nails, etc. are common in people after exposure to this type of molds. In fact, some people experience hay fever or asthma with continuous exposure to Aureobasidium.

It can also cause dermatitis or skin rashes. Therefore, you should never touch this type of mold with bare hands.

3. Alternaria Mold

It is a kind of mold that is often found outdoors. It can grow inside in case of water damage. Surprisingly, there are more than 40 species that come under the Alternaria category. And this type of mold is responsible for degenerative diseases on trees and bushes.

Although a plant-based pathogen, it is the most common form of allergenic mold in the world. It can grow anywhere, there is moisture. This kind of fungi can be identified with its velvety texture. It has a minute hair-like structure which is mostly in dark grey, brown or black.

Since it is airborne, it can linger in the air during dry, windy days and can enter into your house through the breeze. If the space is warm or humid, it will quickly start to build a mold colony. If your home has higher than normal humidity, it is susceptible to this type of mold growth.

It can settle anywhere inside the house – houseplants, furniture, clothing, carpets, etc. It can cause numerous allergies for people inside the house hence you should clear it off and take the necessary mold remediation steps to further prevent its growth.

3. Cladosporium

Another common allergenic mold type is Cladosporium. However, most types of Cladosporium are not harmful to humans and will not cause any serious allergic symptoms.

But there are a few species that can turn to be harmful, so, you should not take it lightly. Some people have reported allergic reactions to the eyes, nose, throat, and skin with exposure to Cladosporium.

A unique factor about Cladosporium is that it can grow in warm and humid conditions. It is commonly found in green or brown shades. The favorite spots of Cladosporium are indoor materials such as fabrics, upholsteries, carpets, cupboards, floorboards, etc. It forms in a suede-like structure which is one way to identify it.

4. Chaetomium

If your home suffers from chronic moisture problems, it will be more susceptible to this type of mold. Chaetomium is one of the commonly found molds in water-damaged homes. It can grow in the foundation if basement waterproofing is not properly done.

If the surface is damp or leakage of water occurs, Chaetomium can start growing. It grows in a colony and takes a cotton-like texture. It can be found on various types of materials inside homes – wallpaper, drywall, door and window trim, paper, baseboards, carpets, cardboard, and furniture containing cotton. In fact, it can also grow inside books or paper.

The color of Chaetomium changes from white to grey to brown and even black sometimes. It often produces a musty odor and can be easily identified with its smell. If left unnoticed, this type of mold can cause health issues in people. It is often related to skin, throat and nail infections for the residents of the house, especially if they have a weak immune system.

If your home is affected by Chartomium molds, you need to find the source of moisture that leads to the formation of mold. Take the support of a house mold inspection company to ensure proper remediation.

7. Fusarium

Fusarium is a toxic and allergenic mold that grows in homes mostly after water damage. It can spread super-quick inside homes in cold and humid conditions. It can spread from room to room as well. Therefore, if you notice its presence, conduct a complete house mold inspection.

Severe symptoms of black mold exposure include nose bleeding, headaches, fever, etc. It is also associated with neurological problems in children. Children are more susceptible to health issues related to black mold.

10. Trichoderma

Trichoderma is a white-colored mold type when it starts growing. Over time, the mold takes a grey or dark green color. This type of mold can cause extensive damage to the structure if left unnoticed for long.
