Nice spec and work Ian .

See, that right there is what built an empire ! .

Yeah we pulled up as the contractors were about to grind the stump. We had a good look, but couldn't determine for sure what it was. There was Armillaria involved but not sure this was the primary agent for the failure. The tree seems to have been privately owned and not the local authorities. It was positioned fairly close the wall where the dysfunction appears to have been. May have been difficult to pick up. Had been reduced a few years ago. Did you get any significant failures during that Easter weekend wind? .

Howdee Nick North Hill in Highgate just below the junction of church road and view road. .

Nice work John, love the set up Was the dead wood over an internal road or public road ? .

Google images Island, I think they were from last year. .

Former Dark paper will highlight the white spore if it's confragosa .
-
I wasn't thinking any further than colour .
-
Even with the size and lack of blushing issues, I think that a weird fruiting of D. confragosa can't be ruled out. Try and get some spore. .

Sounds good, look forward to seeing them. . -

How many trees did you two manage to get the tomagram on? . -

The font of all fungal knowledge Here's your coat sir ! -
A true fung hunter never lets something as trivial as height get in his way. You should have got on Ted's shoulders...............now that would of made a fine fung hunting photo Even the thinnest of slivers can help bag an Id .

It's not Aurantiporus, and I don't believe it be F. punctata. Shame you didn't get a wedge of flesh. Gonna say it was out of reach ain't ya ? Perenniporia fraxinea sometimes does a weird resupinate thing on beech. But without the flesh it's just a guess. .

What's wrong with the Rigidoporus shot, that's one of Hampstead's finest

Gavin, I think you and most people realise that I post my fungi images freely here and elsewhere to share them for peoples pleasure and knowledge without looking for recompence. So in essence I don't mind them being used like this. In fact I'm flattered you have chosen to use so many. Perhaps it would have been an idea to have asked if I would have liked them to be have been credited (as there are actually a significant number of them within your ready reckoner) It's good that you have thought to share the resource though Not sure about the image of the Kretzschmaria. Have you got a better image of it to post up? . .

Guttating Lycogala epidndrum . -
Sycamore in north London failed during the Easter winds Luckily no one hurt. .

Ooops, I mean 11 .

I seem to recognise at least 10 of those images .

The needle is 40 cm long and a couple of millimetres wide. I manage a huge tree population that has epic amounts of dysfunction and associated decay, so to be quite frank I'm not entirely worried about breaching the odd Codit wall here and there, unless it's a highly valued young mature vital specimen. If I need to know what's going on inside due to target safety issues or the actual trees stability then I utilise the technology I have at hand, especially as it costs a fair bit to recalibrate it every year. No point paying for it and not using it. I've done far more invasive things to tress over the last couple of decades .
-
Pretty accurate tbh, though it does depend on type and amount of decay. You'll have to excuse the quality of this image as it's a photo taken from an article we did in last summers AA magazine entitled "interpreting decay" We showed a number of cross sections of lime with Kretzschmaria decay, the oak pictured below, and an ash with the White rot decay of Ganoderma. The bottom left corner cross section of a Laetiporus colonised oak limb corresponds perfectly with the resistograph opposite. (Read from right to left) So much so, that it shows where the needle comes out of the wood in to nothing for the last 7.5 cm. It shows the first 15cm of sound wood, followed by 12 cm of brown rot, followed by 3/4cm of sound wood. .

Think we've had it about 4/5 years Jake, replaced our old Sibtec DIgital Micro probe. .
-
Nice Sean .

Sent Jack up with the Resistograph to help us assess the level of dysfunction and decay in the remaining stem. Three drills - two either side of the lower woodpecker holes where the Laetiporus was fruiting and led directly to the limb failure, and another one half way up the stem between the lower and upper sets of holes. Drill one showing about 8cm of sound residual wall thickness. Drill two showing about 4cm of sound residual wall thickness. Drill three (which exited out the other side of the tree after 30cm) shows both sides of the stem and their associated residual walls and also the decayed core. .
