Which gets us back to my original throwaway comment Rupert; how come the
firewood in my shed doesn't decay as it gets ever drier? Confusing isn't it?

Probably because the fungus dries the timber out, Bill - a lot of them do
that as a strategy to aid their spread through drier (therefore more
aerated) wood
All the best

PS I'de agree re seeing armillaria rhizomorphs over fallen/cut & stacked
dead timber

Hmm; while I'd agree that Armillaria sitting in the dry (under-cover but
not heated or anything) doesn't seem to spread, excavating old whole logs
from the bottom of the junk heap (not under-cover and probably resting on
rotten timber-residues) often seems to reveal logs pretty well covered in
rhizomes, which probably weren't so widespread when the log was put there.
can't say the same for Kretschz.

One fungus that definitely seems to grow on piles of drying timber is
Sooty Bark on Sycamore. I've certainly seen that spread over stacked
cordwood, usually when there was no obvious sooty bark when the timber was
cut.
Strangely such timber burns really well...

That sounds like an interesting observation Julian.
I recall Dr. Glynn Percival at an AA show airspading at the base of a
tree affected by Armillaria, replacing soil voids with pea shingle to
aerate.
Presumably the thought was that this would arrest/limit the disease.
Might be worth experimenting in a quiet part of a woodland by slitting
and inserting a chainsaw into the base of a tree with Kretz to aerate
and knock out/reduce its virulence.
This may stimulate those Eiffel Tower structures that we sometime see
with pronounce buttress flares holding the tree up with little intact
heartwood.

At my last house I got through a couple of Tonnes of firewood a year,
and I only brought the choice cuts home from sites. Living in a
residential area, I made a point of ringing wood up on site so as not
to be using a chainsaw at home. But occasionally there would be some
long sections sitting there for months. I found that Kretz and
Armillaria victims got no worse, basically deprived of internal
moisture they gave up. But the saprophytes wasted no time, I regularly
got Nectria cinnabarina and Stereum but not a lot else. The latter
could render a log fairly useless as firewood pretty quickly. Dried
out logs are anightmare to cut anyway, so they usually ended up tossed
onto on a truck going to the coup, 3 or 6 months after I thught it would
be a good idea to bring them home...
