    See my album on : rhizomorphs of Armillaria.

    IMO a tree like this should as long as possible be preserved as a mycological momument and as an example of the interaction between a tree and wood degrading fungi for the public.
  3. Fungus
    If you're aiming at improving and enhancing biodiversity, you're focus should be on : - preservation of the ectomycorrhizal oaks with the most extensive tree species specific ecosystem of all indigenous European broadleaved tree species, - on all of the older elms, that have a far more limited, though specialized tree species specific ecosystem, - and on the long run on elimination of the sycamores, that are associated with generalistic endomycorrhizal microfungi and have almost no tree species specific ecosystem at all.

    For the bacterial canker causing Pseudomonas syringae pv mors-prunorum oozing gum from the trunk, you'll have to look for this: ---
  5. Fungus
    Quite an impressive example of several fungi working on bringing down and recycling the oak.
  6. Fungus
    Whitish to pinkish oozing of Prunus is caused by a Pseudomonas bacteria, blackish oozing by a Phytophthora species. And the coral spot fungus probably is Nectria cinnabarina.

    Anyone heard of the 19 year old Belgian singer/songwriter[ame=http://www.youtube.com/watch?v=RL4I1xrs6F8]Selah Sue[/ame]with a voice reminding me of Amy Winehouse and Beth Gibbons of Portishead ?
  8. Fungus
    Correct, although M. galericulata decomposes exposed dead wood with polyaromatic hydrocarbons, it's a just a supercially white rot causing saprotroph, that has little effect on the stability of the tree. ---

    Craig, You should be glad you did, because otherwise you wouldn't have been told, that fungi with whitish gills and white spores growing at this height on oak are Mycena's, in this case M. galericulata.

    = P. ostreatus
  11. Fungus
    David, I think you're right, as this definitely is an indigenous species on coniferous wood in New Zealand.
  12. Fungus
    1. Lichens colonizing dead wood live on nutrients that are set free by mycelia of fungi decomposing the wood with enzymes, lichens don't have at their disposal. Besides, the thalli also filter whatever hits their surface transported by air or rain for nutrients. 2. Lichens living on bark feed on whatever nutrients are on the surface of the bark without penetrating living tissues, so how can the cambium become damp and even loose from lichens living on the tree ?
  13. Fungus
    : Pleurotus ostreatus.
  14. Fungus
    Al, Lichens only use the wood as a substrate to "cling" or to attach themselfs to without having penetrating roots, i.e. not to feed on wood by decomposing it, so because they won't damage your house, you should refrain from "treatment" to kill them. They have, just as your green roofing, become part of the natural ecosytem of your house.
  15. Fungus
    David, Yes, IME they are and especially those smooth barked species with a normally neutral, or at least not mainly with negative ions loaded bark surface.
  16. Fungus
    In The Netherlands, the increasing number of strikes, especially on beech, is associated with air pollution (nitrification), because of which the ionisation and with it the electrical conduct capabilities of the (smooth) bark changes, with the sooner attraction of lightning as a result. See : lightning struck beeches.
  17. Fungus
    Gymnopilus junonius (rusty brown spores) is almost completely restricted to deciduous trees and extremely rare on coniferous trees, so if it has white spores, this probably is a Tricholomopsis species, maybe T. decora.
  18. Fungus
    Are you 100 % convinced, that this information is microscopically checked by identifying all of the 6 or 7 species while fruiting in combination with rhizomorphs attached to the mycelium and/or the bases of the FB's ?
  19. Fungus
    The boys on WAB must be diagnosed as splitters then, who seem to be getting in power again after the lumpers have ruled for several years .
  20. Fungus
    David, Is this also true for urban trees in cities with high rise buildings or just for smaller towns with lots of open spaces, like it's the case in The Netherlands ?
  21. Fungus
    Not a myxo, but a "soft tissue" Aphyllophorales, maybe a species from the genus Phlebia or one of its look-a-likes.
  22. Fungus
    The only thing B. utricularis has in common with Fuligo species is the colour of the plasmodium, the aethalia of Fuligo septica and the sporangia of Badhamia utricularis are both different in colour and in shape.
  23. Fungus
    Al & David, 1. Armillaria species can not be distinguised by the diameter of their rhizomorphs. 2. That must be waiting for dead wood to become exposed and available then, because Armillaria lutea (= A. gallica/bulbosa) is considered to be a saprotrophic species.
  24. Fungus
    No, not directly on the exposed sapwood, but on (the mycelium of) fungi growing on/from it, for instance Badhamia utricularis on Stereum species.
  25. Fungus
    No, I don't, in my research I'm mainly focussing on the tree species specific ecosystems of originally indigenous European tree species.
