I need mushrooms for photographs and not for food, so their edibility or inedibility is not fundamental.
Mushrooms are tasty and delicious. If someone take mushrooms from the forest to eat, then it is better to ask an expert, before eating them. The fly agaric is probably the most known poisonous mushroom, so it is not really edible, but some people, mainly in Siberia and are still eating it for religious purposes because of its psychoactive effects. Some people in Japan (mainly in Nagano prefecture) and in Lithuania are also eating it. Nowadays people very rarely die from it.
