It’s pretty simple to gain the knowledge, learn an edible species, learn the lookalikes, and maybe take them to a local mycology club and ask for an ID confirmation the first few times to make sure.

If you avoid little brown mushrooms and pure white mushrooms, know what a deathcap looks like, and don’t spend years eating Paxillus involutus without ever looking it up, then you’re not going to end up eating any deadly or psychedelic species.
