Fungus

We came across this fungus late July, when several of us went to the U of C Open House, held near Barrier Lake, Kananaskis. I'm not sure if it's actually growing out of the log or if it is a "regular" mushroom that just happened to grow a little too close to the log. Don't think I've seen anything with this kind of pattern and texture anywhere else. Doug, have you seen anything the same or similar?
