I would think they are more likely to be G. australe as the tree is in good health currently. Although the basal bracket 'appears' to have nodules on the pore surface which could possibly be the developing galls of the yellow flat-footed fly (Agathomyia wankowiczii) which would make it G. applanatum.

Inspected this sycamore with Kretzschmaria deusta last year and advised the fell. The colonisation looks to have been at a basal wound possibly created during the fence installation. Still had a proportion of residual wall left but progressive decay and relatively high target area, plus visual Id and sounding mallet informed the final decision.

Cracking images Mr Git, particularly like the developing dryads saddle

This Nat geographic story looks at a couple of design students who are making furniture from wood chip impregnated with the mycelium of Fomes fomentarius. http://news.nationalgeographic.com/2017/09/mushroom-fungi-furniture-video-spd/?utm_source=Facebook&utm_medium=Social&utm_content=link_fb20170922news-fungusfurniturevideo&utm_campaign=Content&sf116090384=1 I've often found examples out in the field where the mycelium sticks things together. like these branches which are bonded by a Phellinus species. (Possibly P. ferruginosus) I once left a couple of P. ignarius brackets in flower pot for a few nights (I'm kinda weird that way) and they became bonded together by the mycelium of one of them. looks like like these students might be on to something. .

Earnt ya dough there Reg

Good shout on lycoperdon

Not enough effort in your sales pitch and no where near enough info on ident features, so I'm out, I won't be investing !

Perhaps Coprinus sp

This is Ganoderma resinaceum

Pretty sure they are not from the Pholiota group.

Dan did you manage to take an image showing the stem and the gills?

Likely to be australe, but a wedge showing flesh, tubes and presence/absence of a trama layer in the flesh would help with Id. or microscopy to look at the spore size and ornamentation. have a look at Andy Overalls great article on the differences between applanatum and australe.

Yeah I've spoken with someone involved in the compaction study and mulch applications at Burghley. would of also liked to have attended the tree radar demo up there last year. .

There were actually 5 people there, I invited a tree officer from the Royal Parks along as they were experiencing similar situation with Beech and Merip and wanted to see (amongst other things) what the airspade could/would show. We undertook assessment on 3 other trees with Merip and Grifola frondosa today (see other thread on air spading) so cost would be spread across the 4 trees. It's also our own compressor and airspade. Tbh, I don't think I could put a realistic cost to the day from a contractors perspective. Due to an estimated 7million footfall per annum, we have big problems with managing access and reducing footfall on the roots of trees like this. It's only an aspiration, but if we could divert or spread the weight load I would like to believe that there would be an improvement in soil conditions, but that would likely take considerable time if left to pure footfall management. Ideally the compaction would need to be broken, organic material added and the footfall reduced/limited as an ongoing concern. It was a chilly 14 degrees up here in 'North' London today, normally we undertake air spading in manikins but I didn't really want to inflict the watching Arbtalker membership to that particular sight .

Beech with Meripilus giganteus colonisation (different tree as posted in earlier thread) The following images are from September 2015 when we took the opportunity to uncover a portion of the root flare to assess the dysfunction and decay associated with the fruitbodies. last image is an indication of the general condition of the canopy at that time. With a nod to the original purpose of this thread I've resurrected it as we had the chance to reassess the dysfunction again 2 years on. Again there appears to be little decay in the same area and the canopy density hasn't changed much. It doesn't appear that the initial airspade inspection caused any significant damage. .

Get in the queue matey, we've hosted arbs from Hong Kong, Poland and the USA over the last few weeks, really must get on with some bloody work We're also on Country File next week, which will either be really cool or really embarrasing .

Woodland Beech colonised by Meripilus giganteus and early Kretzschmaria deusta presence. Soil is bagshot sand over clay. Path heavily compacted by regular footfall of dog walkers and runners. Canopy showing signs of dysfunction predominantly on the path side of the tree. (reduced by 3m to limit wind load) Assessment of path compaction undertaken using basic penetrometer. dropping weight at 1m increments from tree out toward drip line across path and also on opposite side of the root plate. Variable readings (from 2 - 10cm penetration) but basically confirmed that the path was the most compacted area. We then fired up the airspade to assess the roots within 3 trial pits. One in the middle of the path and the other two off the path either side of the tree. Unsuprisingly the pit in the middle of path took 30mins to excavate and had limited roots in whereas the other two pits were opened to the same extent within 10mins and had significantly more roots in. In conclusion we believe the path compaction has led to the root dysfunction, developing ideal conditions for the Meripilus colonisation. We are now considering path diversion or spreading the footfall weight at this and other similar tree locations across the site. .

No16 on the map is a new location on the site that is evidence of human distribution, as the sharks tooth its fruiting on has been taken from a tree in the middle of the site and is sporulating roadside.

Yep, I'd imagine so. But it's always worth taking a slice to check flesh texture and colour/depth of the tubes to rule out similar species.

Surprisingly stable at this point, but due to paths either side it's now down to a live standing habitrunk.

Fair girdling of P. fraxinea around the entire base of this ash.

Had you seen our observations on decay mapping/detection of K. deusta Marc?

A common host along with Willow, Alder, Oak

Daedaleopsis confragosa, blushing bracket. what was the host?
