Common Outdoor MoldsMolds are fungi that naturally grow in the outdoor environment that decompose decaying organic material. Common outdoor molds are molds that are commonly found in their natural environment, the outdoors. These common outdoor molds usually find habitation in damp areas on the outdoors where there is a constant moisture source as well as nutrient supply. Common outdoor mold release mold spores that float around in the air freely. Humans are exposed to hundreds of mold spores a day that produced by common outdoor molds. Some common outdoor molds include: Alternaria, Curvularia, Bipolaris, and Epicoccum.
Alternaria is a common outdoor mold that can be found growing in the environment. Colonies of Alternaria can be observed as green, gray, or black thick growth. This common outdoor mold is also known to be a plant pathogen. Alternaria have been known to cause the common plant disease potato blight. Alternaria can also be seen growing on leaves and grasses as black spots. Alternaria may cause allergies in humans, but may cause more severe health complications for people with an immunodeficiency.
Another type of common outdoor mold is Curvularia. Curvularia is commonly found growing in soil and decaying plant matter. Curvularia colonies can be observed as being an olive green or black color when a colonial growth has reached maturity. Curvularia can be a potential allergen to human beings, but usually don’t pose a major health effect to healthy people. Curvularia is not known to produce any mycotoxins that can be harmful to people. Immunocompromised humans can develop adverse health issues due to exposure to Curvularia.
Bipolaris is a common outdoor mold that thrives in decaying plant matter. Bipolaris is also known as a plant pathogen that grows on grasses. As a colony of Bipolaris grows and matures the color ranges from a dark olive green to black. Although some people may have an allergy to Bipolaris, it normally doesn’t have adverse effects on humans. As most molds, Bipolaris would potentially endanger people that don’t have a strong immune system (having HIV or AIDS).
Epicoccum is one of the common outdoor molds that is usually found I soil and decaying plant matter. It flourishes on cellulose-rich surfaces. Epicoccum is a known plant pathogen and which grows well on plants that have been damaged or have damaged areas. Epicoccum colonies range in color from bright red, yellow, orange, and brown. Epicoccum has been known to cause simple allergy symptoms that are closely associated with hay fever. Epicoccum has not been found to be pathogenic to humans.
Alternaria, Curvularia, Bipolaris, and Epicoccum are all common outdoor molds that are found naturally in the environment. Although these common outdoor molds may cause allergies, they play a major role in the ecosystem.
