White Mold spores in the Home - a Photo ID Library for detection and identification of mold allergens What white mold or other indoor mold looks like and stuff that's not mold but may be mistaken for mold MoldAPedia © Enter your search terms Submit search form   Search This Website - InspectAPedia.com Photos of white, gray, & light-colored mold in buildings - how to find & recognize mold on building surfaces Photographs of light colored mold & other molds of various colors and textures in buildings Links to photos of stuff that is not mold or is harmless mold

What does white mold look like on building surfaces and how hard is this mold to see? These mold spores and their photographs and examples of materials sometimes mistaken for mold have been collected in the U.S., Spain, Mexico, France, as well as in other countries where I've studied bioaerosols. These photos of mold on indoor building surfaces may help you recognize mold in buildings, recognize probably-cosmetic mold, and recognize stuff that is not mold and does not need to be tested. Also see Mold Related Illness: Index of Symptoms and for an atlas of building molds and for more microphotographs of building mold samples observed in our laboratory, see Mold Atlas of Indoor Clinical Mold, Pathogens, Allergens & Other Indoor Particles. © Copyright 2008 Daniel Friedman, All Rights Reserved.

Photographs to Help Identify Mold in Buildings -
What white or light colored mold looks like in a home or other buildings

Identification Photographs of White & Light-Colored Mold Growth in Buildings

Here are photographs of often hard-to see white or light gray mold growth on building surfaces. Light colored molds, depending on the genera species, may be more of a health risk than the infamous "toxic black mold" that people look for in buildings. Groups such as Penicillium sp. and Aspergillus sp. can be light in color and difficult to spot on building surfaces, but these molds may produce small, easily-airborne toxic or pathogenic mold spores that present a health risk to building occupants.
