Foraging is a great hobby as long as you approach it with respect. With mushrooms, you start by learning a few foolproof species that have no close lookalikes, and then you learn species by species from there. After a few years of doing it regularly, you'll be pretty comfortable IDing (with a field guide, and occasional help from a good Facebook group -- most regions have a good one, and you need one that's fairly close to you because they'll know the ones that grow near you). I started getting interested around 2013, but didn't eat a foraged mushroom until 2016. I've eaten around 30 different species that I've foraged at this point, all from my area (most within a mile and a half of my house).
