Amanita muscaria is probably one of the most recognized mushrooms in the world because of its striking coloration and large size. This species is commonly depicted on postcards, cartoons, and ceramic figurines. The Fly Agaric is also well known because of its notoriety as being both poisonous and hallucinogenic (see sections on poisonous and hallucinogenic mush rooms). Juices of this mushroom added to milk will kill flies, thus the name Fly Agaric. The yellowish orange formosa variety of Amanita muscaria can be found under pines at Koke‘e State Park on Kaua‘i from December through February after heavy winter rains. Is: KA.
