Common Types Of Mold


Acremonium is a toxic mold that can be seen growing in various colors like pink, grey, orange, or white. This species begins moist but will turn into a powdery substance and change color. Acremonium has a high affinity for water and reproduces easily in cooling coils, drain pans, window seals, and humidifiers. This species can release toxins given the right growth conditions and is regularly found growing alongside Stachybotrys (black mold).


Alternaria is one of the most frequent forms of allergenic mold. This means that symptoms from this type of mold exposure will normally align with allergy symptoms like coughing, watery eyes, and sinus issues; however, exposure can lead to hypersensitivity that can progress to asthma. Alternaria is commonly found in areas with dampness/water damage and can spread at a rapid pace. This type of mold can be identified by its dark green or brown color along with its velvety texture.


Aspergillus is another allergenic mold that is commonly found in homes or businesses. There are over 185 species of Aspergillus which means it can appear in various colors. This type of mold can grow on paper, wood, textiles, leather, electronics, and much more. High levels of humidity or water damage can significantly increase Aspergillus mold growth. With such a large range of species there are many possible health risks associated with exposure to Aspergillus, but the most seen are allergic reactions and respiratory irritation or infections.
