Nameko (Pholiota nameko), is a very flavorful mushroom popular in Japan. Although I've never grown this species, I've read that it does well on cherry logs. Field and Forest Products (fieldforest.net) has spawn for this species, along with info on how to grow it on logs. I'd guess that Oyster Mushrooms would grow on cherry logs as well. Good luck!
