Most of it is true. You can slice them in half and in quaters. From my experience try to get a piece of the mouth in each piece. Unless there gravel or sand on the bottom of the mushroom itself you can't glue it. I put mine in a small tupperware bowl with sand or cc. Cover with bridal vail(sp). Let it sit for a week or two and it should attach to whatever you put in the bowl. Then you can glue it to a rock.
