I admire people with that skill because wild mushrooms are heavenly. My sense of self-preservation, however, is too strong to even pursue knowledge of edible mushrooms. I currently have a stand of chicken-of-the-woods in my back yard that is two feet across, I am pretty sure it's the right thing, but I am still not going to risk eating it. Mushroom toxicity is a bad way to go. "Pretty sure" is not good enough.
There is a woman who collects and sells wild mushrooms at the farmer's market here, and I bought some. On my way home, I realized that I don't know this woman, and I am trusting her with my life. I ended up not using them. I am confident in my ability to identify morels, which grow in abundance here. That's as far as I am willing to go.
