    Yes, P. squarrosa being a biotrophic parasite, I think it is .

    Tobias, No, both F. pinicola, because the very young brackets in the second picture are multi-coloured (reddish-orange-yellow-white), i.e. not just dark red and white, and have pale yellowish pores.

    Tony, Nice and well kept "natural" garden, for the owners. Photo 6 : Lactarius deliciosus. Photo 7 : Clavaria vermicularis. Photo 8 : I assume you mean Hygrocybes, not Agrocybes, because this is Hygrocybe psittacina.

    David, What tree species is this sinuate gilled Tricholoma species associated with ?
  5. Fungus
    David, No, I don't. I only visited these woods with pine, birch and oak on poor sandy soil yesterday, to demonstrate the colonizing strategies of fungal pathogens on pine and other trees to the Dutch participants of one of my seminars and workshops on MTA.
  6. Fungus
    Tobias, Not by asking the same question twice . See this post.
  7. Fungus
    F. pinicola mostly fruits higher up the trunk, mainly develops seperate bigger multi-coloured brackets with pale yellowish pores and is a brown rotter, H. annosum fruits at the base of the trunk, mostly develops a cluster of some smaller bi-coloured brackets with white pores and is a white rotter. In doubt, microscope : F. pinicola spores 6-8.5 x 3-4.5 µm, H. annosum 4.5-6 x 4-4.5 µm.

    Tobias, No, Picea does not have thick bark plates like Pinus has. I have documented Picea reacting to the white rot changing the T/R ratio of the trunk base in combination with the load of the central column weight pushing the trunk base shell down and outward with becoming flask or bottle shaped. ---
  9. Fungus
    Documentation of the effect on Pinus sylvestris of the white rot at and below ground level in the trunk base and buttresses caused by the mycelium of Heterobasidion annosum, resulting in the lower bark plates curling up and coming off at the trunk base long before the mycelium starts fruiting. ---
  10. Fungus
    Documentation of Pinus sylvestris of which the cambium was killed by the rhizomorphs and melanine plaques of Armillaria ostoyae after which the bark was thrown. ---
  11. Fungus
    1. I don't think, it was the Armillaria, that made the tree finally fall over, but the Ganoderma undermining the tree base and the buttresses. 2. I can't help you out on the overbaked pancake laying on the floor of the base. And were there no teleomorphs present of K. deusta ?
  12. Fungus
    I expect this to be on Ulmus and to have white spores. If so : Hypsizygus (= Lyophyllum) ulmarius.
  13. Fungus
    Nice to know you were visiting a watercress farm , but I would like to have information on the tree species the fungi were growing on too .
  14. Fungus
    Judged from the photo there also are no rhizomorphs or melanine plaques present, which implies, that your diagnosis probably is right. Did the bark come off by itself or was it stripped off by hand to show the absence of fungul tissues ?
  15. Fungus
    Andy, I have never seen it before on Sorbus.
  16. Fungus
    I didn't say you said edible, I said that you, by only summing up the characterics of three edible species, left out the smell of an also yellow colouring poisonous species, Agaricus xanthoderma.
  17. Fungus
    Tony, Still a somewhat atypical P. squarrosa IMO.
  18. Fungus
    Andy, Meripilus giganteus.
  19. Fungus
    Graham, No, it probably is Dichomitus campestris with corky annual to perennial FB's, or a resupinate Phellinus species, such as P. contiguus, with hard perennial FB's.
  20. Fungus

    I don't know if I should being compared to someone who could sell ice to the inuits take as a compliment, but the answer to your question is, that I am the primairy source of the information on plaques and rhizomorphs of Armillaria species and you'll have to wait for the publication of my DVD on MTA and the Tree Species Specific Ecosystem next year to "consume" and "digest" the outcomes of my research.

    Drew, You can also have a look at some species of insect parasites on Clive Shirley's hidden forest fungi of New Zealand by clicking on Family Menu : C and then on Clavicipitaceae at the left side of the home page.
  22. Fungus
    Could be, but could also be the same mycelium "rising" up inside the tree without in that phase producing other outside symptoms of its presence (yet) as the FB's, which are formed by decomposing cellulose (energy) of the dead wood (and vinegar acid rich sapwood) by the mycelium.
  23. Fungus
    Suggests or 100 % certain documents R. torulosa from Picea and/or other coniferous trees than Pinus ? According to Breitenbach & Kränzlin and other European Russula specialists, it's only associated with Pinus.
  24. Fungus
    Rob, People don't die or fall into a coma after eating Hygrophoropsis aurantiacus, they just suffer from gastrointestinal disorders after eating to much at a time. And the problem of wrong identification of mushrooms mostly arises from people only looking at the pictures and not reading the descriptions of the fungi in their field guides and thinking, that all poisonous species are documented in all guides.
  25. Fungus
    ... or R. olivacea, R. queletii or R. xerampelina and not R. torulosa, because it is associated with Pinus.
