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...

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...
