This mushroom was found in my front yard, growing in the lawn.
It has a verigate, bell-shaped cap with an even margin. No apparent partial veil and the gills are thick, broad and distinct. The gill edges are entirely even and the gills are almost freely attached. The stem is smooth and center with no bulb.
My best guess for identifying this mushroom is a member of the Mycena genus because it is small and has a rounded top.
