gotta say agree with Mr humphries on this one, ive never really seen it as parasitic, opportunistic yes, and I dont think its that good a competitor either

I think much more able persons may be able to answer that. I would need more information to give you a good guess. More pictures for a start. Once inoculated, whether a tree can stop, compartmentalize, the fungus or not depends on many factors; vitality, species, extent of damaged cells, how much exposed surface there is....

 

species is elm it's a very healthy tree apart from this small area around an old pruning wound just above an inclusion.

 

the fruit body shown in the photo in the op is at the top of the inclusion shown in the photo below. everything below it looks perfectly healthy.

 

cheers

 

simply put it is easier to compartmentalise the wood below than above, when the vessel is broken it is fed from the bottom up, the supply chin is broken from there upward
