I have two yumas that I got for a steal. I am going to cut one of them into 4. I'll let you know how it turns out. I also have a florida that is currently splitting right now. It looks horrible, like the process is killing it or something. It came off the rock about three days ago. It was just kind of hanging out on the bare bottom until I trapped it between two pieces of rubble. When I got all those, I also got one that had been cut in half at the mouth. It has since healed and is doing fine. I say, if you can muster up the guts, just cut them up like regular shrooms. I have read a million different things. garf says you can cut them up. I can't imagine that all the places that have them for sale by the hundreds are just letting them split naturally.
