Mycol Stevens gave a very pragmatic yet funny at times outdoor presentation about edible and toxic mushrooms, then later gave a very informative power point presentation in Andy's living room to help us visualize what he'd told us. The only edible mushroom I've ever felt comfortable gathering and eating is the puffball....I loved his visual cue of slicing one open....if it looks like tofu inside it IS a puffball...if you see gills inside it in an immature button stage of something else.
