Amanita caesarea, commonly known as Caesar's mushroom, is a species of fungus in the genus Amanita. While it was first described by Giovanni Antonio Scopoli in 1772, it was a favorite of early rulers of the Roman Empire. The mushroom has a distinctive orange cap, yellow gills and stipe, and contains organic acids. The species resembles poisonous species including fly agaric. A. caesarea is found in North Africa, Eurasia, and North America. It is edible, given correct identification.
