They are awfully tasty fried up with a little butter and it is fun to go for a hike and find perfectly edible, tasty food right there growing wild. As he mentions toward the end, practically no one gets sick from eating wild mushrooms. For instance in the SW United States there is really no way of mistaking anything poisonous for an edible puffball. Some people are more adventurous and will identify questionable mushrooms from a book, but then you’re really taking care not to eat something deadly and don’t proceed if you are not certain.
