Typically, we see this mostly on the floor in
shelterbelts and under hedgerows. Never really
considered it to be a problem and assumed it was
largely saprophytic BUT . .
Agrios (My 2nd Edition) pp 425-426 does put Xylaria
with Daldinia and Hypoxylon as among the Ascomycetes
fungi associated with slow white rots. Also Xylaria
spp. are associated with "blue staining"
Any help?

I have encountered Xylaria polymorpha on dead stumps
and fallen wood of
beech, lime and sycamore. I can't recall seeing it
on a living tree but
my observations indicate that it is found
principally on dysfunctional
sapwood and/or possibly bark of beech. If failure of
the tree has
significant potential to cause harm, the situation
you describe would
lead me to investigate further the integrity of root
and stem tissues
above and below the sporophores, looking
particularly for damaged roots
and dysfunction initiated by the outward (radial)
spread of a species
such as Ganoderma adspersum and Ustulina deusta.
Hope this helps a little.
