Invasive fungi have caused ecological disasters in the U.S. during the last century. The American chestnut tree commonly grew in forests from Michigan to Louisiana and from Maine to Georgia. In the 1900s Cryphonectria parasitica, an invasive species, commonly known as Chestnut blight, decimated the chestnut tree population leading to one of the worst ecological disasters in U.S. history.
