toad stools are the easist coral to propagate.. got a razor? clean it off good.cut a small portion off of the back of it. i have cut pecies from 4inches to the size of a toothpick and they will grow. also you could pull it out of the water and invert it upside down cut a 1 inch ring around the crown take that ring and cut it into 1 inch chunks. to make them atatch you can use food safe toothpicks,rubbber bands , or go the natural way by throwing the chunks into a small bowl filled with crushed coral in a low current area . they will atatch fast.you should also put some saltwater from your tank on a plate when doing this. put the crown in the water.when you are done disscard the water.when you put the toadstool back in the water . turkeybast the edges of the crown to make sure nothing settels. it will heal very fast. never propagate more then 3 times a year... and never more then one coral at a time.give each coral time to heal befor propagating another. hope this helps if you have any more ? post them. do you have mushrooms?
