I need help decifering what type of mushroom is growing behind my shed. It is near a fence, with a tree on the other side. The mushroom is shaped like a ball but has a stem. I live in CS, Colorado, near Pikes Peak. The mushroom is white with brown pokey things, and a brown top. I am afraid to touch it or even pick it, so my pictures are kind of far away. I also have a small dog, so I would like to know if this is piosens. There are two mushrooms, so it proabably grows in groups. If you are an experienced mushroom hunter, please tell me if it is edible, so I might be able to try cooking it? I really don't know. Go to this site for a picture. The picture is a night, if that helps.
