A common outdoor fungus that can colonize damp indoor environments.
Epicoccum colonies are fast-growing and vary in color from yellow and orange to red, brown, and eventually black as they mature. The texture is typically woolly or felt-like. Its spores are distinctively round and multi-celled with a rough surface.
Epicoccum is primarily an outdoor fungus found on decaying plant material, soil, and grains. Indoors, it can be found on damp paper products, textiles, and other cellulose-based materials. It is often detected in air samples from homes with moisture problems.
Epicoccum is a known allergen that can cause hay fever, asthma symptoms, and other allergic reactions. It is one of the more common mold allergens found in outdoor air and can become problematic indoors when allowed to colonize. Serious infections are rare but possible in immunocompromised individuals.
While primarily an outdoor mold, Epicoccum can establish itself indoors following water damage events, particularly when organic materials such as paper, cardboard, or natural fabrics remain damp. Its presence indoors at elevated levels suggests an ongoing moisture issue.
