We've found I. hispidus decay will extend into wood volumes significant distance (above & below) from where it fruits, although I haven't had the opportunity to disect whole trunks that have had hispidus (only) association. .

Good shot Jules. this is something I've seen on a few tree species. The most prominant I can recall is this holm oak in the stumpery at Ickworth in Suffolk. my reading of the mechanics would be that these 'shelves' are perhaps reaction wood around fibre kinking on the compression side of trees that have white rot, much like that associated with Inonotus dryadeus in the tree below. maybe your ash has decay issues associated with Ganoderma, Perreniporia or Inonotus? .

Looks like Coriolus versicolor .

Significant decay across the buttresses & roots of this lime .

Timothy, that's just plain awful glad you enjoyed the vid Have you ever come down a lime or beech with Kretz that just didn't feel right ? .

a lime tree that was significantly colonised by Kretzschmaria deusta. Too unstable to climb, so we winched it over with an Igland [ame] [/ame] .

That's it, family will have to go cold for the rest of the winter, there's fungi in them there rounds ! .

Probably Flammulina If you're interested, check out the fungi directory and the Arbtalk fungi app for more help on identifying species. .

Thanks Mr Pine .

Cheers Nick, appreciate your comments. .

Cheers fellas, Combo of ground still shots and a guy up the static end of the highline with a camera phone and the main climber (Michal) with the helmet drift cam. There was about an hour of cutting footage, but I decided to limit that as it was very repetitious. So about an hour in total of editing it all together, and about half an hour to save it and upload to YouTube. That's an evening I won't get back We've been waiting ages for the right situation to present itself to employ a high line. Knew we had enough rope and kit to put it all together but I think we'll tweak it if and when the situation arises again. These 'veteran' pollards are by definition compromised by one or more decay fungi and there's been a few that our climbers have come down because of the trees not 'feeling' quite right. Mewp has its place for these types of trees, but we've found, (especially if there's an obliging maiden or two in close proximity) rope access does also. .

Sorry Ben, not sure how to get around that. If I get a chance, I'll try and re-edit so it plays in the US. .

Partly inspired by Tims thread, we found ourselves with an opportunity to reduce a smallish but significantly decayed old beech pollard using a similar high line set up. Ta Mr Pine .

More likely to be Ganoderma sp than P. ignarius. The pore layer on ignarius is more rusty/cinamon than white/cream Phellinus ignarius - Willow bracket - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists Always worth taking a slice out to see the flesh and tube layer. Again, these are notably different between the two species .

Blimey, that looks like it has crane and/or Mewp all over it. Is it leaning toward the road? .

I don't think I can correct you Jules even if I was out to. Not enough info for me to help you (with any certainty) move towards a definitive agreement on Id. It just doesn't look right to me. There are a few species that gutate that are associated with oak that I know of, Aurantoporus fissilis (below) for one, I've also seen Ganoderma sp with droplets on the edge. Although neither of those are your specimen obviously, it suggests that the presence of droplets shouldn't be a sure fire sign of any one particular species. .

A sad loss indeed A few remarks from another thread from a couple of days ago..... http://arbtalk.co.uk/forum/general-chat/84611-oliver-rackham.html .

Is it the gutation and host species that makes you 100% convinced? .

very interesting did you get a chance to cut a slice out of the forb to have a look at the flesh and developing tube layer? .

Odd time of year for dryadeus to be fruiting Jules? .

Had the pleasure of sharing a few ales with him over a weeks residential course at Flatford Mill about 15 years ago. His depth of knowledge across medieval history, ecology, woodland management and the countryside at large was astounding. I'm glad I tried to see him speak several times, he opened the door to ancient trees and woodland for so many people. No doubt many have read his books, but I would urge all that haven't to treat themselves. I for one, will go plant a british tree in a woodland in his memory. .
