If they are shrooms, and you still want the head to attach somewhere else, cut off their foot, and place the head of the shrooms on some LR rubble, glue it to another rock, or wrap it and a piece of LR rubble in some bridle veil. If they are pests, and you want to aradicate them, use methods suggested by Ski. I cant see why you'd wanna move them, just leave em be. They will only regrow, and go back to where they want.
