Types of Mold

Mold is a type of fungus that occurs naturally and helps to degrade and decompose organic matter. To some mold can be considered one of nature’s more disgusting contributions, however mold is necessary to enable nutrients to return to the soil and grow new life. It is normal, but can become a hazardous problem when found in large amounts inside of your home. There are many different types of mold, all with individual characteristics and some with potential health threats.


Effects of Mold on Human Health

Mold can cause health problems or irritate pre-existing conditions. If exposed to certain types for extended periods, humans can experience mild issues such as chest and nasal congestion, a sore throat, dry or sore eyes, skin irritations, or headaches. More severe conditions that mold can cause can be detrimental to your health and include pulmonary fibrosis, immune disorders, liver and kidney issues, neurotoxicity, digestive issues, and heart problems.

Common Mold Types

  • Alternaria has dark green or brown hairs and grows in wet areas such as bathtubs, showers, and underneath sinks. Its allergenic properties can cause moderate respiratory issues.
  • Aspergillus. The most common mold found inside and outside homes. Presenting itself in numerous colours, this type can cause lung infections, aspergillosis, and irritate pre-existing conditions. Aspergillus can be found in different areas of the home and is extremely common following a flood or other disaster causing wet building materials. There are more than 185 different species of aspergillus, some that can produce harmful mycotoxins.
  • Found between wallpaper or on painted wood, aureobasidium is often pink, black, or brown and can cause eye, skin, and nail infections. This mold should never be touched with bare hands or exposed directly to bare skin.
  • Chaetomium. Water damage is a breeding ground for Chaetomium, which can be grey, brown, or white with a cotton-like appearance. Roofs, basements, and leaky pipes are common places, and health issues can include skin and nail infections.
  • Cladosporium. Another allergenic mold, Cladosporium might look a bit like suede and appears in green or brown colours. Wet fabrics, carpets, and other upholstery pieces can develop Cladosporium, which can cause asthma, lung infections, and skin rashes. Like Aspergillus, Cladosporium is extremely common following a flood or other disasters causing wet building materials.
  • Growing in water damaged carpets, wallpaper, and on food/compost items, fusarium is usually pink, white, or red, and can cause dermatitis as well as throat, nose, and eye irritations.
  • This white or blue-green mold type causes bronchitis and asthmatic issues and can be found in a variety of places inside of your home. It is common on fruit or compost items, such as when an orange begins to decompose. When viewed under a microscope there is no visible difference between aspergillus and penicillium as such they are typically listed together.
  • Stachybotrys/Memnoniella. Sometimes referred to as black mold, this green/black mold is slimy and grows in wet, humid areas. It produces toxins that can cause breathing trouble, fatigue, depression, nose bleeds, headaches, and pulmonary bleeding. This is widely considered one of the most dangerous molds and action should be taken immediately to remediate Stachy in any concentration.

  • Serpula Lacrymans. Found mainly on outdoor surfaces, the yellow serpula lacrymans mold affects wood surfaces exclusively and can cause dry rot. It is sometimes referred to as “building cancer” as it can destroy entire structures over time.
  • Found around windows with condensation issues as well as in kitchens and bathrooms, ulocladium can cause serious problems such as hay fever, skin infections, breathing problems, and more. This mold is typically black and smears when wiped.
