    A not that old beech in an extensively managed beech and Quercus rubra woodland on an estate with thousands of old beeches and old to veteran Quercus robur ? I don't think so .
  2. Fungus
    A climber ? It's at 2 metres above ground level !!!

    Please present microscopical evidence of Meripilus giganteus on Liriodendron, as according to my literature this would be a first ever on this tree species. And how did you assess and document the white and soft rot caused by the supposed M. giganteus and the extent of the decay before and the stopping or continuation of the wood decomposition after the wounds were closing ? With your "magic mallet" ?
  4. Fungus
    You may call it what you like, but I've seen all of it, i.e. not just from the side and it definitely is a necrotic bark and cambium canker.

    Thanks for the armchair "theory" on a tree you didn't assess yourself and that didn't fail during rain and/or storm. And as I said before, the ball of rootlets did get some help from the simultaneous white rot caused by and mycelial sheets or felts of Fomes fomentarius, that were before present in (the base of) the split.

    In the first picture on oak, it seems to be associated with vertical splitting and cracking of bark by rhizomorphs of a necrotrophic parasitic Armillaria species. Did you also assess black oozing spots on the trunk ? In the pictures on beech, the vertical lesion or spiral crack could be caused by the inside activity of the mycelium or mycelial sheets or felts of Fomes fomentarius making the tree vulnerable for torsion twist by twirl winds.

    Thanks for your brilliant analysis of what caused a beech standing in the sheltered environment of a dense beech woodland to split and fail.

    That's what it is all about , and that's what the "better Guy" obviously lacks and over and over again tells us a professional arborist does not need for a valid diagnosis and giving advice on management of either "black & white" or shades of "gray & brown" trees just waiting for our chainsaws to bring them down ASAP .

    David, Or G. abietinum ? Not enough developed to be certain about one of these three G. species.
  12. Fungus
    Craig, Yes, you have, as it was first published in 1996 in the Dutch edition of my Encyclopaedia of Fungi (Rebo, 1997). Also see all of my posts on succession of saprotrophic macrofungi.

    Marco, In that order, the Fomes mycelium white rotted the bottom of the poor union, after which the rootlets developed, that split the base of the fork until one fork failed under the outward pressure and fell down.

    Craig, This is Bjerkandera adusta, an annual saprotrophic bracket fungus decomposing heart wood with polyaromatic hydrocarbons. On beech, it is often followed by Trametes gibbosa (see photo), that first kills the mycelium of the Bjerkandera and then continues to decay the wood with a mostly slow developing simultaneous white rot after some time making the tree trunk and (parts of) its crown unstable, which implicates, that the damage to the tree has to be assessed and monitored at a regular basis. ---

    Documentation of a bifurcated beech with first fruiting of Fomes fomentarius after half of the fork came down, with in the centre of the second photo a ball of adventitious rootlets rooting in the moist and decayed wood at the bottom of the split forcing the forks apart. ---

    Scott, Without pictures hard to say what type of bulge formations or buckling creases you mean and what fungi with what type of woodrot causes them. Besides, some of these phenomenons and the pathogens causing them are not included in Weber & Mattheck's book.
  18. Fungus
    David, That really is a shame because it looks like it could develop into something special. And moving on to the next, you've reached Oudemansiella mucida.

    ... if it has pinkish spores, Pleurotellus chioneus if it has pale yellow spores, Panellus mitis if it has white spores and grows on coniferous wood, etc. : microscope.
  21. Fungus
    Yes, but also causing an asthma attack when to much spores are inhaled by people with sensitive lungs.
  22. Fungus
    David, This annual (?) fungus still is so much in its early stages of development, that it is not (yet) possible to put a name to it.
  23. Fungus
    Rob, and I would expect this to be an annual Ganoderma species, such as G. resinaceum.

    Sean, Spore prints are best made by putting a stipeless cap on a thin sheet of transparent plastic (from blisters), so you can either put a piece of black or white paper underneath to determine the colour. And no, I'm not, let's take one step at the time, shall we ?
