Earlier quoted context omitted.
They're really tasty and good for you. There's also a deep primal satisfaction from eating something directly from the wild earth. It's also a long-standing tradition in many cultures. If you know what you're doing and are very careful and cautious, it is a pretty low-risk activity.
The ratio of benefit to potential drawback seems unappealing though. There are plenty of other types of food that would fulfil that "deep primal satisfaction from eating something directly from the wild earth", and orders of magnitude more if you also include the sea.
If you look at a page with our most poisonous mushrooms in Sweden: http://svampguiden.com/giftsvampar/lista/
and compare it with edible ones: http://svampguiden.com/matsvampar/lista/
As someone who rarely picks I would never pick a white mushroom for example because it is high risk even there are edible variants. However I'm sure when it comes to chanterelles and penny buns for example and those (+ one or two more) are plenty for me.
