    Arran & David, Definitely panic fruiting biotrophic parasitic P. squarrosa.
  2. Fungus
    Shane, .
  3. Fungus
    1. Probably Hypoxylon fuscum 2. Resupinate Aphyllophorales, might be Physisporinus vitreus.
  4. Fungus
    Armillaria mellea s.s.
  5. Fungus
    Joe, Panic fruiting of the necrotrophic parasitic Armillaria mellea eventually killing the tree.
  6. Fungus
    David, 1. No, but see this photo of Meripilus sumstinei and this description of Meripilus sumstinei. 2. No, it's not known from the European continent either.
  7. Fungus
    Ben, These brackets look like it's a possibe candidate for Meripilus sumstinei, so if you go back next year also take a sample and have it microscopically identified.
  8. Fungus
    Not growing on, but laying their weary heads/caps for support and to rest on the branch .

    1. P.o. 2. A.m. 3. Russula or Lactarius species ? 4. Stropharia squamosa 5. S. c. 6. On oak ? G.r. or F.h. ? 7. Psathyrella spadicea
  10. Fungus
    Could be a valid explanation, as F. hepatica is a non-agressive parasite investing in getting old with the tree, that is living most years of its presence in an oak on vinegar acids the sapwood secretes to defend the living tissues of annual rings, before it invades the cambium causing bark and cambium necrosis.

    Meripilus fruiting on oak stumps for decades ? Any documentation (pictures) ? And if so, IME oak stumps keep their root systems intact for decades after the felling of the tree producing lots of epicormic growth form activated dormant buds. In fact, the oldest oaks in The Netherlands are standing in a circle surrounding the original (below ground level) coppice with a still intact root system from which the present trees originate.

    Ligniolitic enzymes breaking down lignin first before decomposing cellulose with organohalogens such as PHC.
  14. Fungus
    Tony, The same even more goes for Bjerkandera adusta, which mycelium produces up to three times as much PHC as the mycelium of Hypholoma fasciculare, and much less for Mycena galericulata and some other wood decomposing Mycena's, of which the mycelia only produce half as much PHC as the mycelium of H. fasciculare does.

    1. That willow is characteristic for the managed "grienden" in The Netherlands. 2. You mean pollarded willows like these, of which we may have several hundred thousands in The Netherlands ?
  16. Fungus
    1. See my answers to Treecreeper's questions. 2. They can, because they are non-gouvernmental organisations operating outside the political system and they even have their own specialized lawyers representing them.
  17. Fungus
    It's antagonistic to the mycelium, i.e. not the rhizomorphs, of Armillaria, because H. fasciculare decomposes dead wood with polyaromatic hydrocarbons, the enzymes of the hyphae of Armillaria can't compete with.
  18. Fungus
    Judged by the shot of the cap from above, I would also say it's Armillaria mellea s.l. .
  19. Fungus
    Because of its contrasting colour and shape to the leaves of oaks and beeches it mostly associates with, it's easily detected and then there's the sickly sweet smell, that might attract animals, just as the odour of truffles does.
  20. Fungus
    Neither will you be, nor will you become a "berzerker" , if you don't have your share of the Holy Mushroom .
  21. Fungus
    1. No, I'm not, I said that they would (probably) be pollarded at 2 metres, which was the traditional Dutch way of pollarding willows in "grienden" (see photo 1) and alongside meadows used for domestic and "industrial" purposes, if the trees were to collapse again, because they were not pollarded correctly the first time. 2. The outcome would be, that they had to be cut every two to three years, which nowadays mainly is done by volunteers of Dutch nature organisations. 3. If they are cut at a regular interval, they can get very old and be(come) a habitat for lots of animals, plants (photo 1) and macrofungi (photo 2).
  22. Fungus
    David, Only (young) dogs (as opposed to wolves, jackals and dingo's) raised by humans will eat wild mushrooms, of which they can't see the bright colours by the way, because they are not "taught" by their parents to stay away from food their digesting system can't cope with, as opposed to wild boars and red or roe deer eating truffles, because their parents do. And that's why the Italians use dogs instead of pigs to search for the most expensive truffles.
  23. Fungus
    3/4 : o.k. C.p. it is 5/6 : are you sure ? I would predict it doesn't have white, but brown spores, so you'll have to trespass again to check the colour of the spores to convince me this is not Pholiota mutabilis.
  24. Fungus
    Madame Tree Hugger, Could it be, you hugged the tree so much, the bark became loose and fell off ? But all joking apart, in willows loosening and shedding of bark is mainly caused by (the mycelium of) Pholiota squarrosa or by (rhizomorphs of) Armillaria mellea.
  25. Fungus
    No political career for me , as in The Netherlands, tree foundations are independend public and privately funded organisations closely monitoring and evaluating or - if necessary - opposing to anything politicians plan on doing to trees within the town or city councel's boundaries and ultimately taking them to court to force them to abide to laws on trees and/or flora & fauna or ecology management.
