What is mold?

Molds are form of fungus that can be found both indoors and outdoors. There are thousands of species of mold with estimates ranging from tens of thousands to perhaps three hundred thousand or more. Mold spreads and reproduces by making spores. Spores can survive conditions that are too sunny, hot, cold, dry or wet for mold to grow. When spores are released they can be carried by air or water to new locations.
