any idea what this could be?

Found this one in northern California, in mid January. any help is appreciated thank you. I apologize for the blurriness of the second shot. this mushroom seemed to not have gills and be rounded at the bottom.

Difficult to make a determination based upon these photos. Perhaps there is a partial veil covering either gills or pores on the underside? Seeing the mushroom vertically cross-sectioned may be helpful. Photos taken with the mushroom posed in an open area --but not in direct sunlight-- generally produce better focus and more natural color.
