Eight U.S. states (California, Colorado, Minnesota, Oregon, Texas, Utah, Vermont and Illinois) have officially declared a state mushroom. Minnesota was the first to declare a species; Morchella esculenta was chosen as its state mushroom in 1984, and codified into Statute in 2010. [1] Four other states, Missouri, Washington, Massachusetts, and New York [2] [3] [4] have had state mushrooms proposed.
