We do have elm trees in Tennessee. The are very common. I picked 20 nice morels about a two weeks ago in my front yard. I have found then where cane grows along creek beds and around old rotting round bales of hay. I live near Columbia and I think we should be on the tail end of mushrooms. This year is unusual so they might be popping still. If they haven't popped in your are yet, this warm rain coming up will do it. I have some friends that road hunt for them. They would find gravel roads and drive slowly looking for them. Needless to say they did quite well. Once they find a patch they return every year. Good Luck !!!!
