More about this little fungi:
It popped up in my lawn, same location as last year, my lawn is made of wild grasses with mixes of moss included. Just a single mushroom, no friends about. Though there is what appears to be moss living around it. This is in the northwest of Montana. It is smooth on the back side, no gills that my eyes can see. It is translucent when the sun comes through.
