Mold is mold — it’s not a huge deal, generally just causing musty odors and unsightly stains, right? That’s not always the case. 

Some mold can be annoying but otherwise harmless. However, some mold varieties are more dangerous than others, and you’ll want to address these colonies immediately, or they can impact your health. Here’s an in-depth walkthrough on the types of mold that grow in South Carolina and how to spot them. 

What Exactly Is Mold? 

Mold is technically a fungus that loves to grow in moist environments. It can grow indoors or outdoors and prefers warm and humid conditions. It also likes dark, dim corners of your home like basements or crawl spaces. 

Knowing what environments it thrives in can help you detect and prevent mold growth. It can also help you locate water damage or pockets of high humidity in your home and handle those before it worsens or mold takes hold. 

Mold isn’t always dangerous; lots of mold and fungi are safe to eat or even healthy. But the mold growing in your home doesn’t fall into this category; these spores can cause allergy-like symptoms. 

You don’t have to experience allergies to have a reaction to mold, either. Many people with mold in their homes will notice symptoms like: 

  • Itching 
  • Coughing 
  • Difficulty breathing 
  • Headache 
  • Fatigue 
  • Watery eyes 

If you or anyone in your home has these symptoms, calling a mold professional to check your home is an excellent idea. 

The Common Molds You Could Find in Your South Carolina Home 

What mold are you most likely to find in South Carolina? Here are four examples of common molds and their identifying features. 


Cladosporium prefers to grow on carpet, wallpaper, or subflooring in your home. It’s not always visible, making it challenging to manage without a professional. If you can see it, it’s often brown or black.  

This mold is less dangerous than other varieties and usually isn’t the root cause of illness. However, it can make existing allergies or asthma worse. Additionally, in rare cases, Cladosporium can cause skin, eye, and potentially even brain infections.  

Since it isn’t always apparent that it’s growing in your home, this mold can quickly grow out of control. If you suspect you have Cladosporium in your home, call a remediation professional to handle it. 


If you have mold in your home, there’s a high chance it’s Aspergillus. It could already be in your pantry, as it’s commonly found on starchy foods like bread. You can recognize this mold by the gray-green or white patches. 

Aspergillus can be harmful to individuals with compromised immune systems. It’s also one of the few fungi where an infection is transmittable between people.  

Aspergillus is often in the home’s ventilation systems, plants, and waste containers. Even if you don’t have a compromised immune system, you should have your home treated to prevent infections. 


Alternaria is common in South Carolina but is most often found outdoors rather than indoors. Alternaria is everywhere, often found on plants as brown-black spots. But inside the home, the color varies and can be anything from olive green to gray. 

While Alternaria prefers outdoor vegetation, it can still grow inside your HVAC system or on drywall, wood, carpet, and wallpaper.  

This is another fungus that isn’t necessarily outright harmful and is usually just a catalyst for worsening asthma symptoms or allergies. However, some people with Alternaria sensitivity could experience life-threatening asthmatic reactions, so it’s important to rid your house of this mold when you suspect it. 


Penicillium is another mold that thrives outdoors but is often found with water damage on drywall or plywood subflooring. Of the molds on this list, penicillium is the most colorful. It can be almost any color, including blue-greens, yellows, and pinks. 

It also has some of the most surprising and threatening health risks. Infections like pneumonia, endocarditis, keratitis, and urinary tract infections are all possible through exposure to penicillium mold.  

While infections are rare in healthy individuals, some can create serious complications, so mold remediation services are always recommended.
