Molds can be found in every environment throughout the world, including here in Indiana. Like mushrooms, many kinds of wood rot, and mildew; mold is part of the Fungi Kingdom. Outdoors, molds provide a valuable service to our planet by breaking down dead plant materials along with other microscopic organisms. Molds reproduce through the release of spores into their environments. These spores settle on surfaces and, if conditions are right, amplify into large colonies.
