I've got to take exception to your post. First of all, all of the ones that Ann posted for me are not hollow, and they are choice edibles. Also, if you look closely at the photos, they are all somewhat wavey. And last, as far as not picking black mushrooms, the Black Trumpet is also a choice edible. It's in the Chanterelle family. I've been picking wild mushrooms for over 45 years, and pick them for some of the gourmet restaurants in the area. By the way, I'm not taking exception to your post, just setting the record straight.
