YOU ALSO MIGHT LIKE TO KNOW… There are more of these stately, stark white Amanitas, A. ocreata in the west, and A. volvata in the southeastern United States.  A. verna, A. virosa and A. bisporigera may all be the same species – more studies need to be done. They all have cyclopeptides which kill liver cells. BE CAREFUL when collecting puffballs to eat – a young deadly Amanita, before it expands, looks like a smooth white puffball. Cut your puffballs in half to see if there is a mushroom forming inside; if so, it could be a deadly Amanita.
