beech tree bleeding canker?

[David Goss]

root systems are less likely to be damaged in woodland environment so the merip has to fight harder to get a hold?

I could either provide a short or a long list of references to scientific articles and books on in situ and in vitro research on "fungal attack" and fungal wood degrading strategies all with valid evidence on the subject, but I'm afraid you would not be able to see "the wood for the trees" and as you've already gone to sleep after reading my short reply to your over and over again repeated same questions, I have answered several times, I will refrain from that.

 

 

 

Instead, for those who are awake, I have a simple question : can you explain why Meripilus giganteus is extremely rare to even non-existing for several decades in undisturbed beech woodlands on the European continent and at the same time is present to such a still increasing extreme in managed beech woodlands and on urban and rural beeches ?

 

And why and how has M. giganteus succeeded in attacking so many other tree species as beech, that are not invaded by M. giganteus under original forest or woodland tree species specific ecosystem conditions ?

 

 

Fascinating question ! Care too divulge the answer??

I have similar on an ash tree, but just black tar coming out about 1metre from the ground
