We have a number of large piles of rotted wood chips on our land from about five years old when we had to clear a few trees. They produced quite a few two years ago, then nothing last year with the dry fall in our area. We're happy to see them again.
Oyster mushrooms (Pleurotus ostreatus). I picked and dried a bunch two years ago and we've been adding them to soups and sauces. We're still alive and well.
