Right due to a recent slapped wrist from mr "Veteran" himself I want to evaluate this case in as accurate a way as I casn even if it means paying for analyses at a lab!

 

I have my views and ive 99.99% made up my mind but theres only one man I can really talk to about this:thumbup1:

 

So the old oak that failed IMO due to an aggressive colonisation and soft rotting penetration of the sapwood layer by Fistulina hepatica a rare occurence indeed it has to be said but intense brown cubicle rot by L. sulphereus in around two thirds of the circumfernetial area of the stem left Fistulina with no other survival options. Fistulina panic fruited 18months to 2 years after the failure, the black liquid remains are still there as evidence of thier position in sapwood layers (cambium) the two areas of colonisation, fistulina (deep red) area and golden brown cubical decay) via laetiporus sulphereus are obvious here.

 

this tree failed with a very obvious brittle fracture at the root crown, all brittle surfaces with panic fruiting of fistulina hepatica when panic fruiting.

 

bare with me digging all the images out these are a good start

1. You'll have to evidence and document your hypothesis on F. hepatica (also) causing a brittle soft rot by microscopical analysis of the type of wood rot and identification of hyphae of F. hepatica being the only fungus responsible for this.

2. As I wrote before in a private message, the mycelium of F. hepatica IME only penetrates annual sapwood rings to trigger the living tissue to secrete vinegar acids on which the mycelium feeds until it by travelling inside out via the radial rays reaches the cambium, that is attacked with toxins causing bark and cambium necrosis to develop and the energy needed for the fruiting of F. hepatica only comes from decomposing (brown rotting) cellulose of dead wood.
