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...
