Cladosporium is a common mold found both indoors and outdoors. There are numerous species of Cladosporium and many produce fungal colonies that appear as olive, brown or black in color. In indoor environments, Cladosporium is often found on wet surfaces. According to the Centers for Disease Control and Prevention (CDC), "The most common indoor molds are Cladosporium, Penicillium, Aspergillus, and Alternaria."

Naturally occurring Cladosporium spores in the outdoor environment are present year round in many areas and are known to be a common source of allergens and may trigger asthma attacks. They are also a concern for people suffering from respiratory diseases.

Cladosporium has been recognized as a human pathogen, although infections are not very common. The most common infections caused by Cladosporium are skin and toenail infections. It can also cause sinus and lung infections and corneal ulcers.
