I was positive this was a Clitocybe. Then I looked at it more closely, and now I'm not at all sure. The gills are white and decurrent; stipe mostly white with a slight lilac to pinkish tint; cap of white mostly grayish, toning to white on the rim. Cap 4 inches across, mushroom perhaps 3.5 to 4 inches tall, with a strong bend at the base of the stipe.
