Mushroom foraging gets so much unreasonable fear that it will kill you instantly the first time you do it. And only people with arcane woodcraft skills and a death wish do it. Yes, there mushrooms that can kill you if you eat them. But a lot of the bad ones will just make you wish they had killed you. But you will survive the experience.

And like many human endeavors, such as skydiving, driving a vehicle, swimming, or crossing a busy street, will quickly get you killed if you do it wrong. It takes education and practice with someone that knows how to do it correctly to learn to do it yourself. Mushroom hunting falls into that same category.

If you wish to do it, take some classes. They can be often found in big cities. Go out with proper experienced guides and perhaps learn a new skill. The hardest part is admitting when you ain't sure if you are right and then walking away. Or not. It's up to you.
