    Does anyone have a link to where you could check a plant passport number to identify its point of origin? Just taken delivery of 2 Platanus x hispanica from a local nursery, only one had a tag on with what looks like a PP number. This may be for both trees as a batch. Any pointers would be appreciated. .

    Also check out page 122 onwards of the new book 'Trees, a Lifespan Approach' co-authored by Nev Fay. Expands on the retrenchment paper (above) a little more. http://www.boomadviseur.nl/wp-content/uploads/2016/10/Trees-a-lifespan-approach.pdf .

    Few bits to look up and consider if you haven't already http://www.treeworks.co.uk/downloads/8%20-%20Coronet%20cuts%20&%20retrenchment%20pruning%2017%20April%202003.pdf http://ancienttreeforum.co.uk/wp-content/uploads/2015/02/ATF_book.pdf Retrenchment pruning of ancient trees and lapsed pollards (BS 3998: Appendix C.2) .

    Colour and stem are fairly different, brownish tan hairyish cap and a swollen base with gallica Yellow/honey more scaly cap and a thinner stem that tapers. The rhizomorphs are larger with gallica. Paul Hamlyn's work is a very useful comparison. Honey Fungus - Friend or Foe? .

    I probably know You should have used the search function, there was always going to be an old thread on this lurking somewhere http://arbtalk.co.uk/forum/fungi-pictures/64330-triple-decay.html .

    I have a rudimentary understanding of the science jomoco We're currently involved in an ongoing compost tea foliar and soil drench application study looking at enhancing microbial activity in the rhizosphere of trees stressed by biotic and abiotic factors. The study isn't finished yet so we can't report on conclusions but we have base line soil samples to compare when the studies done. Will start a thread on it later next year. Good link, thanks for sharing .

    Third year of mass fruiting on this 'pollard' that I know of. .

    Even having some Arbgallooph perching on this willow monolith a few years before hasn't put the birds off from taking a pew. Egyptian goose .

    Not related to the original trees of this thread but I was searching for previous threads concerning Armillaria gallica and this one came up. Here are the fruiting bodies of A. gallica and their associated rhizomorphs at the base of this old oak. Not particularly concerned with this situation as the tree is in good health (though hosting Fistulina and Griffola) but as stated earlier in this thread (and other resources) A. gallica is largely saprophytic in nature .

    Hello Kevin, Chalara wasn't a focus of that particular seminar. .
  16. David Humphries
    Yes, I understand it will be available in print at some point. I was with one of the authors today, I'll ask if he knows when and where you can get it. .

    The book (Trees - a Lifespan Approach) is now available as a free download http://www.boomadviseur.nl/wp-content/uploads/2016/10/Trees-a-lifespan-approach.pdf .

    Could be lichen, mould or a crustose fungi.........I'm afraid I haven't a scoobie .

    Can't resist shooting Pholiota squarrosa, it's just too darn pretty Here on beech .
  20. David Humphries
    Done, interesting subject. perhaps introduce yourself and let people know why you are carrying out this survey. You may get more people opening the link that way. I've deleted the other threads you've started as one will suffice, members don't particularly like duplication.

    I would think Pleurotus is worth considering Jules. Maybe even P. dryinus. .

    The aptly named 'plums and custard' (Tricholomopsis rutilans) Saproxylic on the dead roots of this pine. .

    Nice Jules, metal work part of a deliberate access route up into the tree? .

    For identification it's always useful to see the gills/tubes underneath the cap Kev. Not entirely sure on the first ones but maybe sulphur tufts or Armillaria. The second image looks like Armillaria species. Difficult to be more precise with out more visual clues. Last time I as at Winkworth there was a lot of Armillaria around the whole site. .

    Little leg stretch at Anglesey Abbey this arvo, but not much fruiting around. Some remnants of Amanitas and Russulas but not very photogenic. Only thing worthy of getting the camera out was this solitary veiled oyster (Pluerotus dryinus) on an old horse chestnut wound A few shaggy ink caps (Coprinus comatus) and some honey fungus (Armillaria mellea) .
