Hi Rupert,
I agree, I have been monitoring this on a number of trees on varying sites.  
It appears to be completely compartmentalised until the tree becomes stressed 
and then it can appear to extend bark lesions and fruit on bark that has 
recently died.  I spoke to David Rose about this about ten years ago and, if 
I remember correctly, at that time he considered it to mainly a saprotropth 
that may be able to act as a weak pathogen.

Happy New Year

Regards

Luke

Re the last par. of Gerrit's post:
An observation re Kretzschmeria - I have seen it behave as a saprotroph on
old basal wounds on beech, in a stable relationship with actively growing
trees over periods of more than a decade; implying that it too may be
triggered into aggressive growth following trauma - root damage/loss,
pruning, wind-rock etc.

And a final question : is Kretzschmaria deusta an exceptional case, because
it starts out from the heart wood as a saprotroph, changes to a parasitic
mode once the mycelium has invaded the cambium and returns to being a
saprotroph once the tree has died ?

 
And now I shut up too.
 
Kind regards,
Gerrit
