    Ian, Could it be Hypsizygus ulmarius (= H. tessulatus) ?
  2. Fungus
    Colour of spores white or dark brown and stipe with or without ring ?
  3. Fungus
    Any pruning wound with for some time exposed and unprotected heartwood can easily be invaded by spores and mycelium of fast and extensive white rotters such as the tree species specific annual Pholiota populnea (= P. destruens) or perennial Phellinus species such as P. igniarius.

    Je kan de CD hier bestellen. You can order the CD here.

    1 : Entoloma (Leptonia) species 2 : Clitocybe metachroa 3/7/15 : Cystoderma amianthinum 4 : Entoloma (Leptonia) species 5 : Armillaria species 6 : Camarophyllus niveus/russocoriaceus 8/10 : Trichoglossum hirsutum 9 : Galerina pumila 11 : Hygrocybe psittacina 12/14 : Collybia butyracea 13 Mycena pura

    Ty, It's "poplar wet wood" caused by a bacteria, that protects and defends the heartwood of the tree against attacks and invasions of mycelia of saprotrophic wood degrading macrofungi white rotting and/or hollowing the tree otherwise (see photo). ---
  7. Fungus
    It does .
  8. Fungus
    Kat1e, Sure, by looking at the banded pattern around the stem in the second photo, assuming the first photo was of the same Parasol and only finding smooth surfaced stipes on the other Macrolepiota's. And a hint for future identification, the flesh of M. rachodes stains saffran-yellow to reddish-orange on bruising.
  9. Fungus
    Tobias, Shouldn't they first identify the macrofungi and the types of wood rot they cause correctly, before they start using "high tech" 3d equipment to assess the condition and stability of the tree ?
  10. Fungus
    Lycoperdon perlatum is a pioneer saprotrophic, superficially decomposing dead litter, such as leaves, needles, small branches or twigs and bark, so there's no other effect on the roots than decay of the shedded bark and the already dead cambium.
  11. Fungus
    Daedalea quercina is a perennial tree species specific necrotrophic parasitic, although mostly saprotrophic brown rotter in/on oak decomposing heartwood of the trunk of upright standing trees at greater height (first photo), of fallen trunks (second photo) and of stumps (third photo), that are decayed and hollowed in a way comparable to what is caused by L. sulphureus, which also can be present in other parts of the tree (trunk base, major branches) then D. quercina is. ---

    David, Still don't get it when I'm only pulling your leg, do you ?
  13. Fungus
    1. ... and the type of wood rot looks like the type Armillaria causes. 2. .
  14. Fungus
    Tobias, Which implicates, that not only the identification of the (panic fruiting and partially sterile) bracket fungus was wrong, but also the assessment of the type of wood rot and with it the effects on (the stability of the crown of) the tree , a tree in which only those brown rotters were active, that are part of the second phase of the tree species specific life cycle.
  15. Fungus
    Neither have the authors contacted me after I offered my "services" twice.
  16. Fungus
    What about the typical shape of the cap (umbo : nipple), which is characteristic for M.v. And as you didn't assess the smell (M.a. : mealy or of radish, and M.v. : none) either, there is only one option left : go back to collect some specimen and use a microscope for identification.
  17. Fungus
    Sure, but IMO, the information given should not include such speculative information as "... with some evidence of ...", which has no relevance to the daily practice of Arbs what so ever and only creates confusion. Besides, it should have been better to give information on the colour of the spores of Armillaria and Pholiota (and other Agaricales), so that possible mix ups as stated above (Fungus : "You should have looked at the colour of the spores, Armillaria = white, Pholiota = brown"), would have been avoided. I still wonder why the authors did not react to my offer to write a review so that some improvements could have been implemented before the second edition was published.
  18. Fungus
    Page 52 : "with some evidence of a stringy white-rot (selective delignification in the early stages)" : I would like to see valid (microscopical) in situ (P. squarrosa is biotrophic parasitic) evidence of this with relevant reference literature other than given on page 5.
  19. Fungus
    Mick, See my Rhizomorphs Armillaria album, Beech & Honey fungus thread, Pinus & Armillaria ostoyae thread and Quercus robur & Armillaria ostoyae thread.
  20. Fungus
    After having a second look, I think you're both and : 1 and 2 is M. procera and all the others are M. rachodes. Even more now ?
  21. Fungus
    Rather long stalked for M. arcangeliana, don't you think ? Not M. vitilis ?
  22. Fungus
    If it is Ceriomyces aurantiacus, which mostly fruits inside hollows, (also) guttates first and then disintegrates to a powdery mass, you would find lots of cinnamon 7,5-20 x 6-15 µm chlamydospores. And as Perenniporia does't fruit at this height, I. dryophilus still is a candidate : microscope.
  23. Fungus
    Yes, dor or dung beetle (Geotrupes stercorarius) or what the Egyptians called the scarab beetle (= scarabee).
  24. Fungus
    1. In situ, one looks at the colour of the spores on top of caps that are underneath other caps with sporulating gills or on the top side of the ring. 2. Source ? Pholiota species are simultaneous white rotters.
  25. Fungus
    This scarab beetle must be mistaken, holding Laccaria amethystina for a bit of dung she's trying to roll over and lay her eggs in . ---
