    No, definately not Fomitopsis pinicola, I have seen dozens of fresh and desiccated pinicola, this is a Ganoderma.

    australe or applanatum, but need at least a wedge to see flesh/tubes to help determine which one. Microscopy needed to measure spore is the only sure fire way to know.

    Did it look to have as much decayed wood as you thought it would before you felled it ?

    Beech reduction at Highgate Woods in north London with Ali Nicoll & Jack O'Brien up top Nice views

    Looks like Ganoderma sp to me, always useful to try and take a slice out of the fruitbody to show the flesh and tube layer, helps with the Id.

    There is a clone known as the Boabab plane. I’ve seen a few at various locations across London. This may be one of those. http://elmparadise.blogspot.co.uk/2017/05/the-baobab-planes-of-canterbury.html?m=1

    Would imagine it's quite possibly Phellinus pini

    Being left as is, it's in a woodland area within a new conservation compartment.

    Hello Sara, yes the situation in Sheffield is well known here and if you use the search function there are specific threads on the forum for that topic.

    The morphology of the canopy looks somewhat misrepresentative of a virgin crown for tree type in the image. It 'looks' like there is a primary branch/stem missing from the left hand side and that there were perhaps 5 branches/stems at somepoint the past and the canopy has reiterated in the meantime hence the difference in branch diameter from left side to right side of lower crown. Would be interesting to know if there is a large diameter historical pruning wound on the property side of the trunk at about 2/3m at height.

    Yeah, we know we are in a relatively privileged position and I see the frustrations and general depressed state with LA's across the country. Sad state of affairs.

    Ash with an extensive hispidus colonisation (woodpecker holes) that's being retained as a habitat and shade tree on a 10 year topping cycle

    Are you sure it's not Poplar? they look like the holes associated with the poplar hornet moth - Sesia apiformis .

    Maybe the use of % is part the problem here Mark rather than the specific use of linear distance?

    Tbh, I don't know the whole back story Josh I'll have a chat with the case officer to get a better picture. From how the article is written it doesn't seem like the property owners were implicated.

    Nice to get on to some basic removal after tickling about with ancient and veteran trees for a while. Nearly forgot what it was like !

    Thought I'd share this as some might find it of interest. https://www.wycombe.gov.uk/News/2018-March/Tree-surgeons-fined-after-excessive-pruning-of-protected-copper-beech.aspx I don't want this to turn in to a bitch fest about the Arbs (they're mentioned in the article, have no idea if they are AT members or not) but a debate around how TPO's are monitored and enforced by councils and general pruning standards might get some good debate going.

    That's really interesting Greg, were not that far away geographically so its a little surprising that we don't see it fruit on Tilia here at Hampstead. Perhaps the Kretz and Gano compete for wood volume with Rigi here more than where you see it on Tilia in central London? I'll add it to the list a the beginning of the thread. Cheers

    Suspect the first to be Psuedotrametes gibbosa but pore shot would be useful) Thinking the second set are velvet shank, Flammulina velutipes.
  22. David Humphries
    Its associated with brown rot, so doesn't often show adaptive growth in compensating for the decay unlike the white rotters like Gano and dryadeus. I haven't seen any decay detection or cross sections with this decay on Q. ilex, so not really sure how well it can compartmentalise against it.
