White Spots on Trees #2

Ceramic Parchment - Xylobolus frustulatus
Actually white spots on oak logs, the Ceramic Parchment fungus, Xylobolus frustulatus. 
If you stop to look, there's a wide variety of white spots on tree bark, caused by various fungi, lichens, and sometime just features of the tree's bark
Some taxonomic information, X. frustulatus is in the phylum Basidomycota , class Agaricomycetes, order Russulales, family Stereaceae.
At first, I thought these white "spots" were a kind of lichen.  I happened to stumble upon a picture of X. frustulatus while trying to identify the fungus featured in my Conk Watch 2012 post.
