Fragging Elephant Ear Mushroom - How?

[argan]

I would use the sharpest knife you have, (non-serrated) And it should be fine to cut it between the rocks. You could even cut it up to separate the other mouths. I have fragged my mushrooms lots and they always heal no mater how badly I mangle them. Even if there is a piece with no mouth it will probably grow a new one.
