He explained to me that one mushroom was edible and delicious. And that it could be found in the forests in the United States. The other, identical looking mushroom can be found in European forests. That one liquifies your internal organs and causes you to shit yourself to an agonising death.

Oh god, this wasn't "chicken of the woods" (big orange mushroom that grows out of dead tree trunks), was it? Adam Ragusea did a video not long ago about it and acknowledged that mushrooms could be dangerous but figured this one was so easy to identify that there was no risk to telling people to forage it. Even if a mistake is a one-in-a-million chance, the dude has like 2.5 million subscribers so he might have killed 2 or 3 people with it.
