    Yep, Ganoderma. Difficult to say which one. Either australe or pfeifferi Bark crack looks like an expansion crack on a adapting buttress. Evidence of reiterating root growth next to the fruitbody, so may be worth considering a reduction to assist stabilising the tree if there is appetite to retain by the owner? If not get it felled.

    Armillaria sp, possibly A. mellea Always worth scratching around the soil to look for rhizomorphs if you suspect Armillaria.
  3. David Humphries
    Hard (perennial type) or soft (annual type) if the latter I'd suggest Ganoderma resinaceum. Looks like this years fruiting body growing below last years.

    Pale tussock moth caterpillar (Calliteara pudibunda) stumbling over Armillaria mellea on this young dead oak.
  5. David Humphries
    Could be, hard or soft brackets?

    I. hispidus on Oak, really Jules?

    Nice to see that one of the old veteran trees that we manage at Hampstead has been nominated for Englands Tree of The Year. The John Keats Mulberry (sits in the grounds of the Poets home where he penned many classic poems and odes such as 'Ode to a Nightingale'). The fragile tree is reclining and supported by brick pillars having gently subsided many years ago but stayed root intact. Each year there is a heavy crop of juicy fat delicious mulberries which attract visitors to sample its wares but this is perhaps the greatest threat to its continuing longevity. We occasionally reduce the canopy to lessen the load on the old branches. Its up against some very fine contenders from across the English treescape. https://campaigns.woodlandtrust.org.uk/page/30353/data/1?supporter.questions.285157=Tree%207 https://www.moruslondinium.org/map/keats-house Bit of culture for the tree cutters, Benedict Timothy Carlton Cumberbatch reciting Ode to a Nightingale........

    Not enough detail, any shots of the gills, stem or spore colour?

    Might just be a natural flush of fruiting from the change of weather from hot prolonged summer to wet cooler autumn. Loads of species of sapro’s and Myco’s fruiting like crazy down here currently. May not be as a direct effect of the fire.

    Similar but I would think that is turkey tail https://www.first-nature.com/fungi/coltricia-perennis.php
  11. David Humphries
    Last one looks like Psuedotrametes gibbosa
  12. David Humphries
    Beech stump fungi look like young developing Armillaria gallica, tiny blue ones look like Chlorociboria aeruginascens. Soft bracket on oak looks like dried out bit if Laetiporus sulphureus
  13. David Humphries
    Paxillus sp perhaps P. involutus (brown rollrim) Did the LA plant birch?

    Cheeky git ! I've been know to get off the ground (very) occasionally, see last image for pictoral evidence. In my opinion the beauty of the microdrill (apart from the debatable invasive nature of the actual incision) is that you can use it anywhere on a tree unlike the sonic tomographs which can take a while to set up and have issues with interpretation. We haven't got one (through choice) but occasionally bring in consultants with access to Picus and Arbotom so have had the benfits of seeing the results first hand. With all these things, building up a portfolio of knowledge on different tree species with different decay is invaluable and the microdrills give us that experience as we often have it hand and make user of that access quite a lot. Here's an article we penned for the Arb Association magazine a while back looking at interpretting decay and dysfunction with a microdrill.

    Definately dog damage
  16. David Humphries
    Eight years on from the start of this thread and the tree in the first post is still subjected to regular dog damage.
  17. David Humphries
    Normally beech for me too but this was hornbeam
  18. David Humphries
    I try

    Oddity fruiting on heavily decayed roots equidistant between two birch trees. (possible that there may have been another species there in the past but I have no recolection of ash) This bulbose growth has its pores on the surface facing upward. Key'd out in terms of flesh and pores (no spore present) but I have not seen this before so reluctant to say for sure its Perenni.

    What do you think it is?
  22. David Humphries
    Some nice finds during a walk around Thetford Forest this morning.
  23. David Humphries
    Could be an old lightning strike
  24. David Humphries
    Nice find Adam, likely to be carnosum but microscopy would be needed to confirm. Spore size is fairly similar to G. lucidum and a couple of other similar species that may or may not have been confirmed from UK records.
  25. David Humphries
    The Oudies are voracious soft rotters, and it looks heavily colonised. Branches and the top of the tree will start popping off like corks at Christmas.
