Great article, very informative. I have never grown wild vegetables, but would love to give it a try.
We do have some wild berries growing in the area including raspberries, black berries, and blueberries. These berry plants are so prolific in this region, we harvest pounds and pounds of them every year. Recently we ran into this mushroom.

At the time we were not sure what it was, but learned that it was a Lions Mane mushroom. It is edible and very expensive. It grows in this area and can be found growing in hardwood forests.
