This is the picture of the gills of what I believe is a Lentinellus ursinus

I am not sure if this is Lentinellus ursinus, but it the closer I can get. The spores are globulose, a bit verruscose and about 4 - 5 microns. Spore print white. Gill white (as in picture). Cap slightly viscose. It was found in Late February in the South on England (Berkshire) on the stump of Beech tree. On similar stumps I have found nice speicmens of the Oister mushroom. The smell is mushroomy and pleasant. Any suggestions?
