I was casually looking for fungi, and not seeing very much, until I came across about 6 or 7 very large Amanita mushrooms. All had been either knocked over like this one, or the heads had been bent down. Most had been nibbled at or had chunks taken out. I found one piece lodged in a tree. I concluded that squirrels were both nibbling at the mushrooms and also hanging pieces to dry. I guess they don't suffer the same toxic effects that we would if we ate a bit of this mushroom.
