Basidiospores in the Home

Basidiospores are a cluster of spores that may be indicative of a greater mold problem in a home or business. They originate from a type of fungi called basidiomycetes which consists of mushrooms, toadstools, boletes, wood bracket fungi, and puffballs. These spores can be colorless, black, brown or yellow. Although various forms of mold are consistently present around us, the species and concentration level is what ultimately determines the toxicity of the air we breathe in. When the presence of this fungi is detected, it is not necessary to be immediately alarmed, although it is important to be aware of how they are spreading into the home and in what quantity.

Maintaining healthy air quality is incredibly important in the prevention of potentially dangerous respiratory illnesses which is why indoor and outdoor air pollution is such an important topic of research for the CDC (Center for Disease Control), WHO (World Health Organization) and similar agencies. In fact, they’ve devoted a number of resources towards containing fungal outbreaks that can occur from the countless number of species of fungi and mold that exist.

How do Basidiospores Spread Into Homes?


The trouble with Basidiospores in particular is that they may be found just about anywhere. Typically, they travel by wind currents across long distances. However, there are several different ways in which the fungi may find their way into areas of the home. 

The spores are ejected from the mushrooms in which they originate, and then may attach themselves to nearby plants, animals or other organics. They can also remain in air currents for long periods of time, and can end up traveling thousands of miles away from their point of origin. A single spore can even cross several states under the right conditions, before finding its way into your home. Not only is it astonishing how much of a distance these fungi can travel, but equally surprising is just how high of an altitude they can reach. Spores from the fungi have been documented to reach tens of thousands of feet high and attach themselves to balloons and aircraft. 


Another way that the spores are dispersed is by attaching themselves to the insects and animals in which they may come in contact with. Dogs, cats and other animals that are let out for periods of time, may potentially bring the spores into the home without knowing. Common insects such as ants or flies are potential carriers as well. Once inside, the spores may begin growing in potted plants, bathrooms, carpeting, textiles, walls and on anything made of wood. This makes just about any home a suitable habitat for the spores to dwell in. 


Water is another vehicle of transportation for Basidiospores. If your home recently had flooding, or had a leak in the roof, it is possible that the water brought in mold spores with it. As a matter of fact, many different types of mold spores can be transported by water.

Risk Factors of Basidiospores

As with all mold, the health effects that come from the inhalation of Basidiospores are determined by the concentration levels in the air. A minimal presence may not pose much of a health risk or even be detected at all. However, spores that grow in large quantities can be dangerous and in some cases, deadly. The possible ailments range from a number of mild to severe symptoms including: 

  • Pneumonia-like symptoms
  • Cryptococcal meningitis (an infection of the lining of the spinal cord and brain)
  • Asthma
  • Eczema 
  • Allergic Alveolitis (an inflammation of the alveoli within the lung caused by hypersensitivity to inhaled organic dusts)
  • Fatigue
  • Headaches
  • Depression
  • Nasal Stuffiness 
  • Sneezing
  • Congestion
  • Plugged Ears
  • Watery Eyes
  • Itchy Skin
  • Throat Irritation
  • Rash
  • Hives

Mold Removal

Locating the source of mold in the home is important to preventing further occurrences. Most people are already aware that homes and buildings that have been water damaged are prone to mold growth. This is particularly the case in environments that undergo regular bouts of rain, snow or humidity. The most obvious places to check for mold include under sinks, behind toilets, in basements and attics, and under and around appliances that use water, like hot water heaters, dishwashers and washing machines. Moist, rotting wood or discolored tile with a musty odor will provide evidence that mold is present and needs to be taken care of. Many times though, the mold can’t be easily located. It may be inside walls, under carpets or in a crawl space.

The very young, the elderly, and individuals with compromised immune systems are most at risk for health complications related to exposure to mold. If for any reason you suspect that there may be mold in your home, you should schedule a free home inspection by a professional mold remediation company. They will come to your home, inspect the inside and outside, and if they find mold let you know what needs to be done to safely remove it. Having an expert trained in the detection and prevention of mold, fungi, and all other allergens come to your home is an invaluable service, especially for those who suffer from asthma and similar respiratory ailments. Even if you are thinking of removing the mold yourself, it never hurts to get a professional’s assessment of the situation.
