Photo: Diane Edwardson, February 15, 2015. The mushroom caps start off vibrant yellow when they first sprout, then fade to beige & eventually, shrivel into a leathery brown. The largest of these mushrooms was about 3" in diameter. No, I have no idea what they are, other than some form of "gilled mushroom."
