Aureobasidum mold is most often found on wooden furniture, surfaces, painted walls and wallpaper as well as around windows and in caulk. If you notice a spotty substance that is pink and black in color in those areas, it’s probably this type of mold. Since aureobasidum is so common, most people do develop allergic reactions to it and it has been known to cause more severe reactions than other molds.

Chaetomium mold is found in drywall that has experienced water damage. People typically identify its presence when they smell a musty or old odor in their home.

Cladosporium mold is often found inside both cool and warm areas like carpet, wood floorboards, wooden cabinet and older fabrics. Being around the cladosporium mold can leave homeowners with breathing problems and respiratory issues.

Fusarium is a mold that tends to grow in colder, wetter areas. The typical homes for the fusarium mold are carpeted areas and similar fabrics. Fusarium can cause the standard allergic reaction as well as respiratory infections and inflammation.

Stachybotrys Chartarum or Black mold is also called toxic mold. This is due to the fact that this type of mold creates toxic compounds known as mycotoxins. The compounds cause those that breathe the mold in to develop breathing issues, sinus infections, depression, fatigue, asthma attacks and more. This type of mold can be identified by its musty smell and is found in areas that stay damp, like air conditioning pipes and ducts.
