What does brown mold look like when found growing indoors?
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.
