Kinds of Mould

Calgary’s ASTRA Restorations knows all too well the hazards toxic mould can pose to health. Treating mould yourself can jeopardize health and property. Knowing how to recognize mould and its effects, however, is essential to your health and property.

While black mould is the most commonly known toxic mould, there are other moulds that also pose serious risks to your health and property. The most common indoor moulds are Stachybotrys chartarum, Cladosporium, Penicillium, Aspergillus, Alternaria, and Trichoderma.

  • Stachybotrys chartarum is a black mould prevalent in water-damaged buildings and flourishes on damp drywall and wallpaper surfaces.
  • Cladosporium is a fungus that grows indoors and outdoors, can vary in colour from olive to brown to black, and grows on moist organic and inorganic surfaces.
  • Penicillium is a mould used to produce antibiotics. It can grow in relatively low-humidity environments if the surface is damp. Some Penicillium species can produce mycotoxins dangerous to human and animal health, especially causing respiratory problems, particularly in infants.
  • Aspergillus is a spore-forming mould that commonly contaminates root vegetables but is often found on nutrient-deficient surfaces like damp walls. It is a common component of mildew. Some species cause serious pathogenic disease in humans.
  • Alternaria species are ubiquitous in the natural world and commonly cause allergenic and hypersensitivity responses in humans. They also cause opportunistic infections in those who are immunocompromised. While this mould is a normal part of decay and decomposition in the natural world, in the home, these spores grow thick grey, black, or green colonies, producing a variety of toxic compounds.
  • Trichoderma is a mould found in the home and produces small toxic peptides readily absorbed into human cells. These peptides interfere with ion channels and cell function. They are resistant to antimicrobials, which means that primary prevention for this mould is the only effective option for limiting its effects.
