Identification 

One of the rules that I have is that I limit my mushroom feasting to the mushrooms I know very well. As in 100% sure of my ability to identify the mushroom I want. When I want to learn a new one I put in oodles of time to make sure I understand how to identify it and how not to pick a look alike.

Then I proceed slowly because I was sickened by a mushroom that a friend assured me was safe to eat. And for most people, hen of the woods is safe to eat. But not me. It makes me puke.

So when you try any new wild food, and you are sure what it is, eat a very small amount to see how you react. Then wait a few days. I once gave hen of the woods a second chance, and it took two days before I vomited. But interestingly, it turns out that small amounts of hen of the woods tincture is very effective for treating nausea. Hmmm....
