A Quercus robur with two "exploded" necrotic cankers side by side caused by F. hepatica, that have partially been overgrown from both sides, with an extensive zone of smooth bark above the canker to the right caused by a (secundary) infection with Armillaria ostoyae.

would you say the high water table here has had a contributory effect on the health of the tree, ability of the tree to adapt and defend against the decays?

No, the water table is this high because of recent continuous rainfall for over a week. Normally the water table is very low, because the woodland is on sandy soil and the tree are on heightened stands.

looks like theres a lot of brown oak in there?

 

which seems an abnormal amount for a tree of that size. So F. hepatica causes an increase of heartwood?

 

Did you try going into a burr? that would be an interesting result.

 

Also, it could be worth getting the sapwood portion checked out and maybe PCR scanned for presence of the hyphae of Fistulina.
