Mushroom fell off

..or you can stick one of those pins with a plastic ball on the end ( so fish dont injure themselves) and cut a piece of an elastic band into a small square and stick the pin thru the elastic and thru the mushroom into the live rock or what ever you want it to stick to. Snug the elastic down the pin to keep it in place. Couple days should do the trick! or if you want more mushrooms you can just cut it with a utility knife into 4 pieces and do the same with a pin and elastic.
