I've had some success with growing Landscape Morels (
Morchella importuna) in my garden. Check out this thread I started a while back:

However, because of recent research indicating that some cardboard is contaminated with nasty "forever" chemicals called PFAS, I would advise caution about my method. In fact, I'm currently trying to figure out how to modify my method to eliminate cardboard, or how to test for PFAS in cardboard before using it.
Everything Mushrooms was a mushroom supply company based in Knoxville, Tennessee where I used to buy my morel mushroom spawn. Unfortunately, they seemed to have gone out of business. So you might want to check out Field & Forest Products in Wisconsin for morel spawn, as well as info on how to grow them. They have excellent mushroom growing kits and have lots of info about growing morels. They are very helpful and even will answer your questions over the phone. Good luck!
