Dead men and their parts

Once again it is that time of the year when the fingers of dead men start to erupt from the ground.
Fear not, they aren't the fingers of real dead men but the fruiting bodies of a fungus known as Xylaria polymorpha. Dead man's fingers, are a saprobic fungus, that is to say that they get their nutrition from dead and decaying organic matter. They are a common inhabitant of forest and woodland and usually grow from the bases of rotting tree stumps and decaying wood. Can you spot the tiny red mite?
Staying with the theme of dead men, the "extra" is a lichen-covered carving atop a gravestone in the  in the ancient graveyard of Cill an Alein (Chapel of the Beautiful Place) on Mull. I am puzzled as to what it is meant to represent. Any ideas?
