I found two mushrooms growing near each other under coast live oak, blue oak and manzanita. The gills and stipes looked the same to me, but the pilei not so much.They both have pink at the base of the stipe so, for now, I'm calling them the same. The pilei have what look like scales that are closer together at the umbo and breaking up as they get closer to the margin. The pilei are 5.5 and 6 cm wide.
