Winter mushrooms
Growing inconspicuously inside a huge hollow stump (probably an oak, based on the size and location), I nearly missed these mushrooms. It was December 24th 2014 and the cluster of caps glistening there looked like--if you'll pardon some zookeeper earthiness--a pile of deer scat. But it was levitating near the rim of the hollow stump, so I stopped and angled my camera down to look at them from below. I will guess that these are Mycena mushrooms, pending confirmation from the experts.
