oak disease

Scott, not to say that theory isn't true, but I'm wondering...

 

How could there be fire damage where there is a stone wall?

 

Did the bark sound hollow when tapped with a hammer?

 

Did you try removing dead bark to see what was inside?

 

Did the tomograph indicate any irregularities at the surface?

 

Based on experience dealing with dozens of these types of infections in North America, the cambium inside the recessed area will be infected or dead, and there will be no rhizomorphs or other evidence of a macrofungus.

 

One treatment that seems to work over here is to remove dead material, nourish the surrounding roots, and look for callus swelling at the margin and closure over time.

 

Whatever the pathogen (if there is dead tissue), if there's a more reasonable protocol i'm all ears. The good news is, if the wood is not decayed, risk is low.
