Bracket Fungus.

I spotted this bracket fungus on a mossy tree as we were walking the dog earlier. I clambered through the undergrowth to get a bit closer and then noticed the slug slithering around. As the sun wasn't showing it's face yet I had to use flash for some light.

I was going to call this, Where's Hinge? But wasn't sure how many folks would remember Hinge and Bracket.
