Giving the impossibly high standards people here have for identifying a mushroom, it’s a wonder that they would eat a mushroom at all. You may not trust an LLM, but how would you even trust yourself? Who would you ever trust?

I don’t anyone here has indicated that they have "impossible" standards. If you think "gather only mushrooms that you definitely recognize as edible; if you have any doubts, leave it be" is impossibly high, I’m not sure what to say. Of course what "definitely recognize" means in terms of the odds of a false positive is subjective, so sometimes people get poisoned. Even more rarely a poisoning leads to death, but people who die from mushrooms they have picked are those who didn’t heed the warning at all.

Mushrooms are best treated like firearms; that’s not an impossibly high standard.

Why would you want to eat a random wild mushroom so badly in the first place? We're not starving, wandering through the forest for anything which might be edible. Entire regulated industries exist around selling and growing human food grade mushrooms.

Curiosity is great. Take a picture, enjoy what you find in nature. At the same time, stay safe and resist the urge to throw a random mushroom down your throat just because you might be able to unless you're willing to put the work in to make doing so reasonably safe. If you do reaaaaallly want to try a mushroom you can't find for consumption otherwise then it's worth the heavy amount of verification. 99.9999% of mushrooms people normally care about eating can more easily be found without foraging and self-identifying though.

Honestly, yeah. I wouldn't eat a wild mushroom. The ones in the store are good enough for me.
