Acremonium

A toxigenic mold, Acremonium often begins as a moist patch, and evolves into a powdery substance that is most commonly found on drywall ceiling tiles, or inside window sealants, humidifiers, or drain pans.

Acremonium can be white, pink, orange, or grey in color, and should be avoided when possible because it can cause some serious damage if left untreated over time.

Alternaria

Alternaria is certainly less toxic than Acremonium, and whilst it can cause fungal allergies, reports of infections suggest that it doesn’t occur frequently.

This mold type loves to grow on plants, food, and rotting manure, and due to this, it’s often found outdoors. It’s been suggested that Alternaria is developing resistance to some fungicides, which means it could become more of a problem in the future.

Aspergillus

Aspergillus is one of the main culprits for causing respiratory damage such as asthma in a large portion of American households. Whilst it begins its life as a mere allergenic mold spore, it can become more toxic over time.

This mold produces many colors, so it’s not always easy to discern from other types of mold. However, it mostly creates chain like mold trails across surfaces. Luckily, Aspergillus is mostly found outdoors, on water damaged buildings or structures.

This is a mildew type of mold that thrives in colder climates and can usually be found in damp windowsills or behind wallpaper. It’s most commonly black, although it can also be pink, so it’s quite easy to spot.

Aureobasidium can be an allergenic mold, so it’s best not to breathe it in, and it can also cause rashes on the skin and itchy eyes, so you should never touch it.

This type of mold is most commonly associated with plants and can cause severe allergic reactions or asthma attacks if you become exposed to it indoors.
