Yellow Stainer

This little mushroom was growing where I have found the yellow stainers before.  I bruised the cap with my thumb to check and it immediately turned yellow.  There are others that bruise yellow but I am fairly sure of my ID here.
It is quite a while since I looked in the woods next to the office for fungi and I found quite a few nice little mushrooms.  There were a couple of the red spotted Amanita but they had gone over and wouldn't make a good picture, there were also some dog stinkhorns just appearing as a small white 'egg', I will try and go back in a day or two to see if they turn into one of these fine specimens.
