Eddie, they are talking about food type mushrooms, not the cattle poop, vision quest kind......
In Montana, after a forest fire, the Morels, pop up all over. They have scores of people heading out with their buckets. Never tasted them, but I hear they are quite tasty. As for puff balls, never ate them either. It takes about 6-8 hours for the symptoms of a poison mushroom to take effect, but by then most of the damage is done. I would eat a Morel, but I would be hesitant to eat a puff ball, for fear of gettin a wrong one. The ones Hillbilly mentioned I have heard of before, and the oyster, and the other ones also. But I would not know for sure which was which. I have heard that tree ears are edible. It is supposed to be what is in the Chinese soups, and dishes.
There is an old Wives tale, that if you stick a silver spoon in a mushroom and it comes out clean it is edible. However the Deadly nightshade, will not tarnish a silver spoon, and you do not want to taste one of those!
Dang those are some big puff balls! Just imagine the puffs they would make!
