Blastomycosis is a lung infection typically caused by a fungus that grows in moist soils, leaves, or rotting wood. It can also spread to the skin and other parts of the body. Mushrooms, mould, and mildew are examples of funguses. The fungus that causes blastomycosis grows as a mould in the environment, a yeast in human tissue, or as a yeast in the tissues of different mammals, such as dogs and cats.
