    Cap morphology can be affected by a number of things paticularly in development. Temperature, virus, parasitism etc.... Not always a solid I'd feature. I've learnt that it's more useful to hone in on the core markers like pore/gill type, species association, spore colour, smell. At first glance I thought your example was an Amanita, as I've seen the solitary Amanita (A. echinocephala) look very warty like yours. Iwasn't until I saw the pores/tubes that I realised it was a bolete type and the oak was then a good indicator towards radicans. The staining was the key on this one though. Geoffrey Kibby (who agreed on your one being H. impolitus) wrote a great book on the Bolete genus which is well worth the investment, as are the Russula and Amanita versions. http://www.summerfieldbooks.com/british-boletes%3A-with-key-to-species---5th-edition~3041 .

    Talked to a couple of people (including my tame mycologist) and they felt it was more than likely the iodine bolete - Hemileccinum (Boletus) impolitus. Based on time of fruiting and the yellow pores it would be either Boletus radicans or the above. As it didn't stain they believed that impolitus was the best fit. It's common name derives from a distinct smell of iodine from the base of the stem. .

    Warty cap is throwing me. No books here so your on your own. .

    Boletus would be my first port of call, and was originally thinking B. radicans. Though lack of blue stain after exposing the tubes/flesh to the air makes me think it would be something else. Out of curiosity did it stain after you took the images? Great shots by the way. .

    Peter was a joy to be around, a great man of trees, I learned a lot. No reps from Asia or Oz Book is still in editorial, I think the idea will make it a great piece work. I'll update on when it's due out if and when I can. .

    No apologies for resurrecting such an old thread. Plenty of people may have missed it first time round. We rarely use the Block driver as we don't take down too many trees these days, but over the years it's been a useful tool to have in the truck. This pole didn't warrant using it today as it was too skinny, but it was a good opportunity to show the young lads on the team what it was all about, especially as it was in a tight spot. Team leader Ali's first play with it aswell. Still a great design Reg. .

    Don't think you need me to back this one up Chris. .

    The Arbtalk members allow you this break Christopher (you probably deserve one)..........however, don't make a habit of it or you will be banned Look forward to reading more of your (Arboricultural-styled) 'Facts of the Day' in due course .

    Tree Radar can be utilised via ground penetrating radar to determine the presence or absence of tree roots in these situations. We recently used consultants to see if/where veteran oak roots were in relation to a tarmac path. Tree Radar Lloyd Bore - News Item .

    That's one of your best vids Reg, great camera set ups and love the drangon fly at the end. Tight spot to rig with the other trees and power lines, fine work as usual. Serious question - any consideration given to reducing the tree? Looked to be very well sheltered. You'd obviously stripped the lower canopy to help climb/rig it. Was there anything in way of lower canopy to reduce it to? Any identification of the decay culprit? Ta .

    How old is the fence? Possibility that some of the roots of the trees were damaged during the construction/erection of the fence. This may have resulted in the branch dieback, which in turn can lead to the presence of saprophytic organisms. .

    I thought it was a good article about you, the accident and the Perennial charity in the recent Arb Magazine Sean Nice that they've used some of your own images, helps give the piece a sense of you, more than just the written word would have. .

    I'm always amazed at how little vascular tissue is required for a tree to maintain itself to some degree or other. .
  16. David Humphries
    That's a good one ! .
  17. David Humphries
    Possibly, guess it depends on whether there was any vascular connection last year .

    Not entirely sure Jules, but the helical fluting suggests something interesting is going on inside that section of trunk. Would be fascinating to put a Resistograph (or tomograph) through it at various locations. Did you sound it? .

    Definately one of the Ganoderma's, and likely to be applanatum, but without a look at the flesh/pore layer and confirmation of spore size then I couldn't say for sure which species it actually is. Was the tree in leaf at all, or was it standing dead? .

    Tree was more than likely in some level of decline before the piptoporus mycelium started to move through the dysfunctional or damaged wood in the trunk or branches.
