Join a local mushroom foraging group, whatever you find nearby that is native/naturalized, would be a great addition to your food forest.
But here is my shortlist:
Chicken of the Woods
Chanterelle
Morel Mushrooms
Black Trumpet
Lion’s Mane
Giant PuffBall
Shaggy Inkcap*
Field Mushroom (Agaricus campestris)
Hedgehog Mushroom (Hydnum repandum)
Fairy Ring Mushroom (Marasmius oreades)
I also think that you can widen the list by including
medicinal mushrooms, or even more if you include just support species fungi, that doesn't have macroscopic fruiting bodies, but are immensely wonderful for the plants and soil.
Iterations are fine, we don't have to be perfect
