Fungi on Deadfall

Yay that the tractor is (almost) fixed! Thanks to a new fuel filter and some sage advice from Farmer Al, my husband got the tractor running. He did a great job grading the road. 
My photo is of fungi growing on some deadfall that I brought up from the woods. They looked a little like seashells to me. 
This is a combo of HDR stack and focus stack. It was a bit of an experiment.
