Howdee Rob, how's the project coming along? .

Did you get a feel for who the attendees were made up of ? .

The fungi is Inonotus hispidus. Have a look at the fungi directory in the tabs above for some information on decay type, hosts etc..... Don't know the second set in terms of Id The last is a prunus species .

Sounds a very interesting project sean. So who are the UK players (that we would of heard of) involved? .

I thought he did .

Here be more afore, during and after shots, 2 & 4 showing four years on. .

Wavy Man ! .

Hi Will interested in how you came to not find this (Collybia fusipes) on the Arbtalk Fungi App? Host at least should of helped narrow it down. Always worth cross referencing with the directory here on the main site once you've got a few potential suspects from the app...... Collybia fusipes - Spindle shank - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists Any thoughts will help go toward honing any potential future updates with the app and/or directory .

Happened about 5 years ago in very strong winds. Felt like I wanted to give it some attention imediately afterwards but we had much higher priorities at the time and it has slipped down the pecking order. It would happily take a reduction and has produced some epicormics on the newly exposed lower inner crown. Its gone through some pretty strong winds since (last St Judes being the most significant) and had no more loss. Nev Fay was suitably impressed with the failure on a stroll looking around our trees and some of their issues. .

Oh go on then, just cause its you .

The Hornbeam had height & weight reduction in 2010 due to the resinaceum. We continue to monitor annually & give it the occasional tap with a nylon hammer as & when passing. The willow is leaning significvantly away from the target of the path so could be left entirely but if oportunity arrises we will reduce it to keep it standing longer. Oak will have a retrenchment phase at some point. .

Random........ Mr Sidebottoms tribute to the Smiths 'Panic' Wonder who cleared up the big beech failure? .

Three tree with seperate issues. Willow that has succumb to attack by Armillaria Oak that has had a large limb failure due to the brown rot Fistulina. & a Hornbeam with Ganoderma resinaceum. .

Grifola here on a couple Prunus. Not unheard of but uncommon and a first from my experience. .

Hi Al did you carry out the reductions? If so (or not) how are they this year? .

you may jest Mr Bolam, but even the more fervent of us fung hunters get caught out by odd looking metal work now and again. Thought my luck was in when I saw these, which I reckoned looked like Phellinus robustus from what was (to be fair) a fairly long disatnce away .

bout time you binned that old camera sean ! the images are fuzzy as hell Nah, like that mate, has a good texture & contrast mix. How's the bristol arty thing coming together? .

Yep, spot on .

Hello Sadie, thanks for posting your tree and its issues and welcome to the site. There are some good threads here at Arbtalk that discuss the varying health issues that affect Horse chestnut specifically. Try the search function for more information. But basically your tree is indeed suffering with Cameraria ohridella (chestnut leaf miner) which can have an effect on the photosynthetic process of the tree making energy. This does have an effect on the vitality and the ability of the tree to go through its natural processes with enough energy to burst buds, grow flowers, set seed and rejuvenate each year enough new wood and capability to compatrmentalise the decay. There are products on the market that control the leaf miner for a couple/few years at ago. Involves soil drenching, micro trunk injection and /or foliar spray. The bracket fungi inside the tree is either a Ganoderma species or Rigidoporous. (Would think it's more likely to be Rigidoporous) the decay is at an advanced stage and ongoing. Looks like the tree has been reduced or topped at least once (probably more often) which can help with the stability but this tree species will such to the decay at some point as it continues to hollow it out. Hope this helps .

Yep, think this is honey fungus. .

difficult to say for sure off those dessicated images. On oak they may be spindle shank Collybia fusipes when look to get an Id with fungi, its very useful to get shots of the stem, gill & spore colour if possible. David

Difficult one, dryadeus would seem to fit the bill. Never had any, hear that it's good eating. Not entirely comfortable in taking fruitbodies from large public trees that may aid an inspector in the identification of a structural issue. But if in abundance, I guess harvesting with an nod to the above & conservation of the species is ok ? .

first shots are from a small gathering of Hampstead & Windsor Arbs in '09, the update shots were indeed from this Sundays field trip for the AA Conference .

The second one (King Offa's Oak) is listed on the Ancient Tree Hunt Map as 'Private - not visible from public access (permission required to view') The Woodland Trust | Ancient Tree Hunt | Tree details The first one (The Conquerers Oak) is listed as 'Public - partial access (e.g. next to footpath or road)' The Woodland Trust | Ancient Tree Hunt | Tree details .

King Offa's Oak, thought to have been growing since AD 710 ! Here festuned in Fistulina fruitbodies (couple more on the far side out of shot) .
