I'm skeptical of anything with "easy" and "morel" in the same sentence, but since this was one of the ur-questions of hubski, it seemed imperative to give at least one good answer.
About 8 years ago Luke died and we buried him in my parents yard. Every year around memorial day, there would pop up a small group of Morels where Lukes grave was. -No kidding it happened for several years. Best dog ever. My parents live in MI, I'll let him know about "easy grow mushrooms" but I don't think he'd do it. For him, it's all about the hunt.
Morels have come to embody "home" for me. They, like Tigers basesball, Michigan football, the Great Lakes and canoe trips, are intrinsically "Michigan". It's good to be home.
We found some in the back yard of a house we were renting a couple of years ago. They were delicious.
