Found this on the underside of a branch the other week...and thought it was reaction growth to a fracture but once split the fibres didn't really look as though they had undergone any excessive stress however the lower half is definately looking darker and the cambium layer does look disrupted?? Any ideas?? the branch was otherwise normal

Could be fibre buckling. Why don't you cut it longitudinally - you might be able to see the buckled fibres if it is.

Medullary rays are pronounced in upper half but recessive beneath...discoloration is extensive...bacterial? Do as the man says & see what you get!

Good plan! Wish I had i'll try and find it..

If you consider the loading / force / lever dynamic of the scenario, it is not likely that a broadleaf tree will try and support weakness in this way ....

Cheers Vdub - was that one of those "pull-the-ivy-away-and-oh-great-look-what-I've-anchored-into" moments??

[vduben]

oh yes!! it just had 1 limb that span out 30ft! also was horizontal cracks in the dead wood on the tension side!

You may have seen this before but I have never seen it so pronounced.

 

Adaptive growth due to Ivy strangulation.

 

You can also see in one of the picture why a non 4x4 is no good for me.
