This observation is the same tree and the same location on the trunk of the tree.
I was able to dry the conk, ID # DD695

I’ve been back to this tree every year since 2008 and so far, there have not been any other conks growing on it. I’m hoping to find one in good condition and dry it. It is the only live oak tree I’ve seen Ganoderma fruiting on.
