Sounds like your gram gram was overly careful.

Foraging for mushrooms does not require huge amounts expertise. It requires a little bit of common sense.

If you regularly went foraging, it would have been possible for you to learn a few easily identifiable and unmistakable mushrooms. At least in the Nordics (and I assume it would be the same near by), it is quite easy to teach another person a few mushrooms to forage for when you can show the mushrooms growing in the wild and explain the few identifying traits.

If you take a 6 year old mushroom foraging you tell them not to eat any mushrooms without showing you first, because it requires an expert ;)
