Sorry, I didn't want to pull the mushroom off to look at the underside of the cap so that other people can enjoy looking at them. (My other photos showing the gills were with mushrooms already pulled out by other people or animals.) I was afraid to kneel down to look because of my bad back. I forgot to bring a mirror. I looked at pictures of Pholota terrestri, and they are very similar to mine, at least the cap and size. Thanks a million.
