Dear All
Please see the link below to a Picasa photo album of the development of a
Ganoderma fruiting body on an oak. I would be grateful for the opinions of
the forum as to its identification.
The Epsom TO's, Jeremy Young and David Gadsden, identified the tree as Q.
cerris and eventually concluded that the Ganoderma is resinaceum, though
they were surprised at the rate of growth and size.
Regretably, on the day it was felled, I was unable to get back to the site
in time to get photos of the base of the tree and the patterns of decay
resulting from the fungus, before the wood was removed and the stump ground
out. A section at about 5m though, including through one of the bleeding
tarry spots, presumably resulting from either a phytophthera or a bacterial
canker [is this the current debate about ''chronic oak decline'' similar to
that previously about Horse chestnut bleeding canker? Might then the new
allicin treatment be comparably effective?] that have been evident in recent
years, clearly shows an earlier and current episodes producing 'codit'
boundaries.
