Green mold refers to various fungi that have a greenish hue and grow on surfaces, particularly in moist environments. Here are some common types of green mold:

Is green mold dangerous?

  1. Aspergillus: This is a common type of green mold often found indoors, especially on damp walls, fabrics, and food. Aspergillus species can range from green to yellowish and may cause respiratory issues if inhaled.

  2. Penicillium: Known for its blue-green color, Penicillium can grow on spoiled food, wallpaper, carpeting, and other indoor materials. It can cause allergic reactions and respiratory problems and is also a source of penicillin.

  3. Cladosporium: This mold often appears olive green or black. It thrives on wood surfaces, textiles, and even HVAC ducts. Cladosporium can cause allergic reactions, skin irritation, and respiratory issues.
  4. Trichoderma: Usually greenish-white, Trichoderma is commonly found on water-damaged wood, paper, and walls. It can be particularly destructive to materials and may produce toxins harmful to humans and animals.
  5. Fusarium: Though it comes in a range of colors, Fusarium is sometimes green and grows on plants, damp carpet, and wall insulation. It can cause eye and skin infections and respiratory issues in humans.

Identifying green mold accurately often requires lab testing, as the color alone isn’t always enough to determine the specific type.
