oh wow: Zombie mushroom hand. This Clathrus archeri, or "Devil's Fingers" - looks like a cold, dead hand reaching out to pull the rest of the zombie body out of the earth. Those even look like tattered sleeves down by the wrists of the hands!
There is a giant mushroom in Oregon that is over years old, covers square miles of land, and is still growing - HOWEVER, it is NOT THIS MUSHROOM. The Oregon mushroom looks like many small fungi spread across miles of land.
