Next time I find a puff ball I will photo it and post. I am assuming they occur here where I live now, Vermont. When I was in Michigan you could find them in the right weather conditions anytime from the middle of August through October. They are the only type of their kind that is so distinguishable, as they are VERY large. I have no hesitation selecting and eating them. Puff Balls and Morels are easily identified wild mushrooms and safe to eat.
