    Tony, From my own experience and research, as far as beech is concerned, I can fully agree on this .
  2. Fungus
    Although I have documented many examples of the opposite, this may often be true for beech and some other tree species, but there are many other tree species, which are killed by rhizomorphs blocking the nutrients and water transport to such an extreme, that the tree dies within a few years. I've seen lanes of close standing poplars die within ten years after the first tree was infected with rhizomorphs - which can grow up to one metre a year in a straight line from tree to tree - through root-root contact. And also remember, that "das grosse Waldsterben" (the massive dying of forest) with mono-cultures of spruce in Germany (Bavaria) and the Czech republic was caused by Armillaria ostoyae as the primary pathogen.

    Could be, could also be a non-poroid Aphyllophorales with a smooth hymenium.

    Alex, The snake is associated with and/or a symbol of drugs being used, which later was transformed into the caduceus, the symbol of the medical profession. And the Tree of Knowledge in the Garden of Eden, from which the forbidden fruit was picked, is no apple tree, but either is the Fly Agaric (see : Adam & Eve : Amanita muscaria and the first photo), or the Liberty Cap (Psilocybe semilanceata) as is depicted in the bronze doors of Hildesheim (see second photo), in which panels Adam and Eve, instead of a fig leave, both hold a "harvested" cap of Psilocybe semilanceata in front of their genitals. ---

    Could you upload an enlarged photo of the "crustose" fungus ?
  6. Fungus
    Yes, it does ... just as trees associated with ectomycorrhizal macrofungi can become a parasite of "symbiotic" fungi under specific circumstances, and that's why I prefer the "symbiosis" to be seen as a delicately balanced state of mutual parasitism.
  7. Fungus
    Tony, Correct, as I was only referring to the brown and white rot producing species of annual or perennial bracket fungi in/on birch and red oak from my research top preference list.
  8. Fungus
    In my experience, woodpeckers only make one hole in a nesting tree. The reason for pecking/testing the top is, that the brown or white rot mainly is found underneath the top of the scar and/or a FB sticking out, so the effort to hollow the tree needs less hard labour, i.e. with brown rot the bird just has to "jump up and down" a few times to create a deep enough nesting cavity . Besides, this way the bird keeps a roof close over its head.
  9. Fungus
    Can you upload pictures of its crown at the affected side of the tree ? And the "rot" in the wound doesn't look like the type of (white) rot caused by Armillaria to me.
  10. Fungus
    Tony, When was this article published (the BBC page shows no date) ? I heard of this Dalarna pine before, but I also heard from within the European myco & tree circle, that this claim had to be withdrawn, because of a lack of (scientific) evidence.
  11. Fungus
    Matt, Rob & Tony, Read this on the relationships between climate or season, trees (oak, beech) and (ectomycorrhizal) macrofungi.
  12. Fungus
    Sean, As these relationships are on an one on one species base, I would expect your indigenous Lenzites species (L. acuta) - provided it also is a parasitic successor - to be specialized on another indigenous bracket fungus, which could be a Trametes species too. And concerning other successive (parasitic) macrofungi, see : Succession of fungi and my contribution on Tremella aurantia to David's Fungi Directory.
  13. Fungus
    Guy, I withdraw from this senseless and time consuming discussion with someone who refuses to understand my message and seems to be in need of an special hearing aid. Please direct your questions and remarks to someone else. Good luck on your efforts to solve a problem you'll never get a grip on by using invalid methods of non-scientific "research".
  14. Fungus
    Sean, 1. No, the parasitism is the other way around, Lenzites betulinus kills the mycelium of Trametes versicolor. 2. No, my information comes from several different sources.
  15. Fungus
    Oh well, so here's a scan of a snap shot of the Lebanon cedar and the Mimosa tree on Cyprus taken years ago from quite some distance. ---
  16. Fungus
    It is killing the mycelium after which the hyphae of the successor fill in the "tunnels" created by the mycelium of the first colonizer of the wood, which is "prepared" for further decay by the successor through the wood degrading enzymes or polyaromatic hydrocarbons produced by Trametes versicolor or Bjerkandera adusta.
  17. Fungus
    My field research has shown, that in The Netherlands, birches brown rotted by Piptoporus betulinus are top favorite, followed by Quercus rubra brown rotted by L. sulphureus or Daedalea quercina and then by Q. rubra white rotted by Phellinus robustus. With these bracket fungi, the nest openings are always situated underneath the annual or perennial FB's forming an awning, as is shown in the photos of P. robustus and D. quercina on Q. rubra. ---
  18. Fungus
    No, this is based on well documented in situ and in vitro research done by others. And the same goes for Lenzites betulinus (see photo also showing Panellus stipticus) killing the mycelium of Trametes versicolor. ---
  19. Fungus
    And documentation of what the sap wood of a beech looks like after the bark is thrown and the rhizomorphs or plaques of or superficial white rot by Armillaria are exposed. The same trunk is covered with lots of perennial brackets of Trametes gibbosa, which started fruiting after its mycelium had killed the mycelium of Bjerkandera adusta. And one FB of Coriolopsis trogii is present too. ---
  20. Fungus
    I saw this magnificent tree years ago, but made the pictures with an old fashioned analog camera unsuited for reproducing and uploading. If you ever go to Cyprus, you can find there the tallest and oldest Lebanon ceder accompagnied by the oldest Mimosa tree leaning against the defense tower of a destroyed castle annex to a cane sugar factory founded and exploited by the Knight templars in the 15th century, of which I only have old fashioned photo's and negatives too .
  21. Fungus
    .
  22. Fungus
    How many increment cores do you need to just have a bit of a complete picture of the extension and amount of the white (and soft) rot ?
  23. Fungus
    Tony, Only possible if you had x-ray eyes .
  24. Fungus
    Wow, that's some prolific annual fruiting. If one only could have a look inside this ash (?) to determine how much wood of the central column and how many radial rays (dormant cracks) are gone and to check the inner structure of the tree and its stability besides the shell of sap wood rings keeping the tree upright and looking healthy.
  25. Fungus
    Scott, I'm not sure, but I think both, because in the old days, gardeners and tree nursery men were not taught to "disinfect" and seal the open grafting wounds properly and not all of the Dutch notary trees at this and other locations, where they almost always have been planted as solitary trees, have this infection.
