    One of the Pleurotus species perhaps .
  2. David Humphries
    Difficult to be sure, but I would lean toward Gymnopilus junonius, the spectacular rust gill. Have a look on the main websites fungi directory....... .
  3. David Humphries
    I wouldn't particularly disagree .
  4. David Humphries
    + 13 thousand views suggests that people are interested in the thread Chris. The diversity of topic your sourcing is what makes it compelling, keep it up .
  5. David Humphries
    Quality aside, the effort is appreciated .
  6. David Humphries
    Yep, squarossa In my experience, canopy decline is usually associated with root death/dysfunction. That's the time to slip the scabbard and do unto tree what tree would do to thee .

    Some bits and pieces from Epping Forest earlier today Agaricus silvicola (wood mushroom) Scleroderma citrinum (earth ball) Chlorociboria aeruginascens (Green elfcup) Oudemansiella mucida (Porcelain fungus) Pleurotus ostreatus. (Oyster mushroom)

    Nice that you noticed and good that the Arbtalk Fungi Directory resource was credited. T'is a fine periodical .
  9. David Humphries
    Have you ever looked at pooling one or both with other arbs in your area Gary? .

    Fluting, sounding hammer and a couple of Resistographs confirmed the extent of the dysfunction and decay so we took the decision to remove the tree instead of topping it. We also took the opportunity to give our new apprentice some airspade time to have a look at the associated dysfunction caused by the rhizomorphs (which were abundant in the soil) and the mycelium of the Armillaria where it was active on both the cambium and within the central cavity. .

    A lime tree from a Victorian landscape that has tipped over the edge in terms of stability. Armillaria (probably mellea) & Ganoderma (probably australe) colonising the same section of the base of the tree. .
  12. David Humphries
    Based on host tree species, location of fruit bodies & buttress flare, I would suspect young developing (rhs) and older fruit bodies (lhs) of Meripilus giganteus, (the Giant Polypore). But I would echo Felix's request for closer images for a better chance at a positive Id. .
  13. David Humphries
    Possibly the key point whilst assessing Armillaria is to identify which species it may be. The UK has 6 species Some of these are similar in appearance and may be only differentiated by size/shape of spore. As there are species that are relatively benign, (as opposed to aggressively pathogenic) or act as secondary parasites and even wholly saprophytic, then it's important to know which one you're presented with. http://arbtalk.co.uk/forum/tree-health-care/81240-armillaria-investigation.html .

    The circling doesn't sound too good long term. .
  15. David Humphries
    I've not airspaded this one yet Gary, but I've noted the fruiting on it for at least the last 5 years (perhaps longer) It doesn't 'sound' too decayed, and the canopy is still vigorous. Where I have seen wind throw on ash with associated fruiting of P. squarrosa there has usually been very poor canopy on the failed tree, suggesting substantially decayed roots. .

    Excellent Jules, have driven past a few times but never taken the opportunity to a have sniff around the back. Thanks for sharing Interesting that the leaves aren't going over yet, ours in London are starting to turn. .
  17. David Humphries
    some Friday fung.... Pholiota squarrosa on ash, Pholiota aurivella on same ash, Armillaria and Ganoderma on lime and the last shot is my tame dog stink horn eggs Mutinus caninus.....in a pot ! .
  18. David Humphries
    That's kinda cool Paul (obviously not so cool for the whale, but cool nonetheless) Here's a set in north London being used as a gateway to a private woods, that I used to walk past regularly .
  19. David Humphries
    I'm hopeful that the BS guidance (without getting in to the debate on how expensive it is) and the micro guide, are a great step forward to where common-sense, the use of endoscopes, sounding hammers, mirrors, torches etc, are common-place tools in the arsenal of most practicing non (Bat) specialist Arbs. We'll see. .

    Hello Terra firma, although I'm a little puzzled to your description, I'm inclined to agree with Mr Alinicoll that the images look like a mycorrhyzal Bolete species. From host tree and from what I can see in these images, I would lean toward Xerocomus chrysenteron. Out of interest, what do you mean by "the lower had tight gills"? The fungi section on of the PTI is open book, and relatively straight forward. You are very unlikely to get mycorrhyzal fungi in the test. My advice would be to concentrate more focus and resource on the practical inspection and tree law. Welcome to Arbtalk. .

    Phaeolus schweinitzii here at the base of cherry (within cherry/pine woodland ) at Epping Forest. If directly related to the roots of the tree, then it would be a relatively rare association as P. schweinitzii is usually to be found on gymnosperms. Very few records of it on broadleaved trees on the FRDBI pages Agent Arb took these images yesterday. .
  22. David Humphries
    or perhaps use the fungi directory in the above links on the main website or even the Arbtalk Fungi App Smart Phone Apps for Arborists - Brought to you by Arbtalk .
  23. David Humphries
    That or the veiled Oyster Pleurotus dryinus perhaps, but that would present with a a partial veil lower down on the stem. Can't see that in your images. .
  24. David Humphries
    Agreed .
  25. David Humphries
    Will be interesting to know how many MP's actually do turn up to the meeting. .
