Are you talking about mushroom hunting? i.e. going on a walk to try and find them in the wild?
I would really recommend against that, without good experience, knowledge or guidance who knows what kind of mushrooms you pick. They could be bad for you and the dose can be harder to guess if you don't know exactly what type it is.
Instead grow them yourself, for example with a kit. It's more fun without a kit though.
Visit the website called 'the Shroomery' if you are adamant and still want info on mushroom hunting. We don't really do that here since it involves IDing.
