I don’t claim to be a fungi expert. If this is a mushroom, toadstool or plain old spore, forgive me. Nevertheless, I found this while walking along the Olentangy Bike Trail. I have eaten many, many mushrooms over the years, but never harvested my own. I became especially fascinated by mushrooms in the wild after reading ‘The Omnivore’s Dilemma‘. I think they make interesting photos.
Here are a few more, but in color — the markings I find interesting.
