The "secret" to attaching any mushroom is low flow. If they don't already come on a little piece of ruble, get a piece of rubble and put the mushroom on it. Then, cover both of them with either a clear cut out bottle top or a clear plastic cup with little slits for a bit of flow. Give the mushroom 3-5 days and it'll attach itself to the rock. Then all you have to do is glue the rock with the mushroom to any place you want.
