I have a rock with 4 large mushrooms that are doing very well; when I bought it, it also had a beautiful smaller sized orange colored mushroom with the cluster. The green mushrooms have grown so big that they cover the smaller one. Can I remove/split that mushroom from the others and have it grow on its own on a rock or something? (Forgive me if this is a dumb question - I couldn't find anything on this subject through the search feature.)
