Ancient Tree Forum Summer Conference '16

Some more images of the tree noted above.

For whatever reason, this beech died and still remains standing. Because of this - or even since - I noted both Ganoderma sp. (most struck me as being Ganoderma applanatum) and Kretzschmaria deusta colonising the wood substrate. I very much like the first photo below!

[David Humphries]

This thread won't get overrun with Ganoderma (I promise!), though there really were some sweet examples in the New Forest. Here's another one, split over two posts, showing how a three-stemmed beech has catastrophically failed after being extensively colonised by what is probably going to be Ganoderma australe, and since the failure of the stems there appear to be further Ganoderma that have begun to produce sporophores. I suspect some of these may be Ganoderma applanatum, but I'm only going on morphology on that one, so it's by no means definitive.

 

The colours in some of these photos are incredible, as well. No change in contrast or anything - this is exactly how they were taken with the camera, with no effects.

 

Interesting that the middle bracket in this image hasn't gone geotropic since the tree fell, suggesting that this area of mycelium/fb's has ceased to be active.

 

Fine set of images Chris, sounds like a good meeting.

Indeed! A few others did respond and change their angle of orientation, though for some reason that one didn't. Perhaps the mycelial network was suddenly subject to undesirable climatic conditions, or was inactive prior to failure?

Here's a small polypore on a dead and heavily-shaded branch (it may have been ash - can't remember) that I think might be from the Polyporus genus. My initial reaction was Polyporus leptocephalus, though Ted Green commented that it could be a species of the Lenzites genus, though he looked from a few metres away. Short answer: not sure on this one.

[Kveldssanger]

Here's another one I am unsure about. I am leaning quite markedly towards Fistulina hepatica in a dried state, on this beech (Fagus sylvatica). Need a second opinion, though. Again in the New Forest, prior to the ATF event.

leptocephalus has a black foot hence the common name

 

I would think this is just squamosus with the squamules washed off by rain.

Fh is pretty rare on beech but there are records across beech, ash, sweet chestnut and ofcourse the more usual host of oak.

 

Flesh, tubes and pores look OK for Fistulina hepatica.

So, if it were still active, would it change from horizontal (when the tree was vertical) to horizontal as the tree lays potentially then showing successive growth in 90 degree change of pitch on a single fruiting body? Or would it somehow, re-orentate the whole of the existing fb?

 

I've never seen that (never even thought to look for it mind.) I will now!

The former, some fine examples on his old thread.....
