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!
