I’ve had a lot of people ask me for recommendations on a good visual guide for foraging mushrooms, and this is one of the best overall guides that I’ve stumbled across! I would also highly recommend looking for foraging guides specific to the region that you live in, as I’ve seen a lot of very focused regional guides that would be especially helpful in making sure you’ve got what you think you’ve got.
Caution: Never, ever, ever eat a wild mushroom that you aren’t 100% certain is what you think it is.
