indeed, that is they way:thumbup1:

 

and its quite remarkable how many "experts" there are out there that have never done so!

Thing that I find really interesting about these shots are the aerial roots it was putting down prior to failure either side of the dying butress in the first shot.

yes, and everytime i see them I think of Gerrits views.

Found this beech stump in a hedge today. Looks like colonisation by Kretzschmaria deusta also so I took a couple of images as I thought somebody somewhere might be interested (other than me of course)

My boss told me he had seen a big beech failure not a million miles from home, but in the opposite direction to home, so been waiting for an early finish.

 

It was indeed a fine failure and well worth the trip. As we can see there is intense white rot , the fungi in this case is I suspect Ganoderma australe, but what we also see in attendance is kretzschmaria deusta in a vein of dysfunction that extended right up into the stem and probably an old dead root trace back to a long dead limb.

 

From my short investigation I deduced that this pocket had been completley rotted out by Kretzschmaria deusta complete with psuedosclerotial plates walling off the gano that had colonised all but a thin band of sapwood (T/R was over the limits by a long chalk) Only when the vitality had been compromised by this invasive and very agressive Gano species had the kretzschmaria found a way into new volumes and one can see the defined zones and the clear division between the hard brittle (soft rot) via the Kretzschmaria and the ductile failure in the white (simaltaneous rot) Ganoderma.

 

This one really got my juices flowing!

the white (simaltaneous rot) Ganoderma.

 

Great documentation of the white rot with selective delignification of the Ganoderma.

is the selective delignification an early stage though? with more complete degradation later?
