I once attended an AA seminar where Roland (?)Fox and Lynne Boddy did a
fantastic double act on fungi, most of it straight over the heads of the
audience but....

They showed agar plates inoculated with Armillaria and saprophytic fungi
commonly found in woods an guess what, the saprophytes were antagonistic to
the Armillaria, is this common knowledge, not seen it mentioned here or
again, can anyone shed further light on this issue. It seems to back up Ted
and others who see dead wood as good and would explain why old woods with
fallen timber are not dead woods, even when in Oregon.

 The thought of chipping an Armillaria riddled stump
 and liberally applying the freshly prepared inoculum
 still fills me with horror. Ditto Meripilus >>

Yeah, my brain mills these things over and concludes something very
similar 
Alan. However two years? is that excessive? How long does it take to rot
down 
thoroughly? I've left woodchips on the truck overnight and had them
steaming 
thoroughly the next day. I heard ADAS were going to do some research but
then 
heard no more.

Now when it comes to spreading a freshly prepared inoculum from an
Armillaria 
riddled stump it sounds bad, but doesn't this 'latent decay fungi' theory 
suggest that the fungi are present anyway? And when it comes to this 
principle how did nature cope? I assume that some trees died of Armillaria
in 
the wild and presumably they shed their 'riddled' parts beneath them. The 
trees survived despite this. Mind you I suppose the 'pioneers' colonising
the 
space were probably different species to the 'climax' trees, maybe
Armillaria 
resistant? 

I believe that the largest organism on the planet is a patch of Armillaria
in 
a wood in Oregon somewhere. Not knowing what sort of Armillaria is a
problem 
but the wood still sounds like its a wood, not a dead wood! Armillaria
just 
doesn't seem to work like that although I accept that I may only see
things 
from my narrow view. (Sorry out with Ted Green on Saturday!)

Sorry to hear about your slipped disc. Touch wood; I've never suffered
back 
problems much, disc trouble sounds horrible.

Cheers.
Bill.
