    Could be one of the saprotrophic look-a-likes of K. deusta, such as Eutypa scabrosa, Anthotosma decipiens or Glyphium elatum : microscope.

    Annie, The tree being your neighbour's, shouldn't he be the one to have the tree assessed by a professional arborist ?
  3. Fungus
    ... triggered by what went on "behind the scenes" before, which forced me to post my "mission statement", followed by this hypocritical reaction.
  4. Fungus
    ... starting more than 400 million years ago in symbiosis with cyanobacteria and developing from 420-370 million years ago into lichens (Prototaxites), a symbiosis of fungi and algae, so even then there was no leading role to play for a single organism.
  5. Fungus
    Neither in human, nor in forest or tree species specific ecosystems, a single organism or a family of species plays a leading role without total or partial dependence on the support or cooperation of some or all other participants. See my post on contextual (eco)system theory : point 2.
  6. Fungus
    Yes, not a problem and no, the white hirsute state is (the cover of) the scale insect and the red "corals" are the teleomorphs of Nectria coccinea.
  7. Fungus
    Where (U.S., Australia, New Zealand, Europe ?), on what species of Quercus and how old were the trees ? Any documentation on the assessment of the (tree species specific) effects on the condition and stability of each of these Quercus species ? Attacking strategies, softrot and/or white rot ? Body language of the trees, bark and cambium necrosis ? Co-existence with Fistulina hepatica and/or Laetiporus sulphureus ?
  8. Fungus
    Or Cryptococcus fagisuga, a scale insect associated with Nectria coccinea, a parasitic Coral spot fungus causing bark necrosis and canker. Annie, The cavities used by the squirrels could have been created by the mycelium of Pholiota aurivella (see the Beech & Pholiota aurivella thread). Did you ever see fruiting of this fungus from one or both wounds ?
  9. Fungus
    Tim. Until now, no.
  10. Fungus
    Annie & Rob, Polyporus squamosus is an annual (necrotrophic) parasitic bracket fungus, that decomposes dead wood to produce fruitbodies once or twice a year and lives on as a dead wood feeder (saprotrophic) once the tree has died. In beech, it is a slow decayer, that can create intensive white rot and cavities on the long run. So the question to answer first is : over how long a period and how often has the mycelium been fruiting and how many years has the canapy been looking thinner ?

    David, After you sent me a copy, I twice offered the authors to review the publication, if necessary correct the text and to add information (f.i. on Oudemansiella mucida) and literature (f.i. Manual on Wood Decays in Trees, Weber & Mattheck) on the wood decay strategies of some of the macrofungi depicted (f.i. Fistulina hepatica; identification and different strategies of Ganoderma australe and G. lipsiense) or excluded from the text (f.i. Armillaria ostoyae; A. lutea) and on other tree hosts of bracket fungi (f.i. Inonotus hispidus : Ulmus; I. cuticularis : Acer) than listed. I also offered to add my photo's of the different types of wood rot, photo's of Armillaria rhizomorphs and photo's of excluded species (f.i. Fomitopsis pinicola; Phellinus robustus; Chalara fraxinea) to the next edition.
  12. Fungus
    And it wasn't the first time. So what other car related black foam rubber materials did you include in your diagnosis then ?
  13. Fungus
    Guy, If you doubt Tony's expertise opinion on this, read what Weber & Mattheck in Manual of Wood Decays in Trees (page 72-73) have to say on and documented of the effects of I. dryadeus on oaks in an urban or roadside situation.
  14. Fungus
    It could be mites trying to find shelter in cracks in the bark to survive the winter period. If so, the species (Eriophyes leiosoma, E. tiliae, E. lateannulatus) can be identified by the characteristics of the galls they produce on the leaves in spring.
  15. Fungus
    1. Neither was mistaking motor oil for K. deusta, which still is an essential element of your snappy "formula" and "diagnosis" :lol: . 2. Not all, but some - such as K. deusta - are .
  16. Fungus
    Rob, Although I don't think it can be done effectively after pruning, trees do direct their foliaged branches towards lampposts standing in between lane or roadside trees to "collect" the orange-yellow or bright white light at night.
  17. Fungus
    1. No need to ID the fungus ? Any fb coming out of the sapwood is no good ? How do you assess the effects of an unidentified fungus, of which most are saprotrophic white rotters only superficially decomposing dead wood and how do you assess the mycelium is constricted to invading living tissue (sap wood), which would mean it is a parasitic macrofungus. 2. That is what you thought ? What did Kd in your snappy "formula" refer to then ? So K. deusta in reality is motor oil ? There goes your diagnosis of an aggressive soft rotter responsible for hollowing the tree down the drain. Is this your idea of meticulous assessment ? 3. Tomography without properly identifying the macrofungi first ?
  18. Fungus
    David, I'm not sure, but I assume the (sudden) increase in light triggers redirection of the (stored) growing hormones, such as auxins, towards the dormant buds and then the branches grow towards the light source while "embracing" the trunk (photo 1) or are bent downwards to protect the bark of the lower parts of the trunk (photo 2). In The Netherlands, the trunk of newly planted beeches or beeches suddenly exposed to light after other shade providing trees have failed or been felled, are covered with jute or burlap (photo 3). Also see Overexposed beech with extreme sun scald. ---

    I only know the term "marcescens", which means "wearing a skirt". And yes, both Carpinus and Quercus sometimes hold on to a winter "skirt", especially when planted in hedges, with the most dense foliage at the side exposed to direct afternoon sunlight.
  20. Fungus
    Beeches don't "tan" or thicken their bark when suddenly exposed to sunlight. Solitary beeches or lanes of older trees activate dormant buds at the 12 o'clock side of their trunk and bend down the new branches to bring shade to the bark (see photo 1), or "embrace" the trunk with branches from dormant buds at the opposite site (photo 2) if no or not enough dormants buds are present at the most sunny side to protect the bark from sunburn. And younger free standing beeches surround the entire trunk with branches with dense foliage, that even stays on the branches in winter and is shed when the new leaves are formed, as is shown in the third picture. ---

    Pete, Not if he was communicating a self fullfilling prophecy .
  22. Fungus
    1. Already having a "tonsur" because of too much and too often exposure to acid rain, I would if I could ! 2. There are, but what other species of Inonotus are known and documented from Robinia ?
  23. Fungus
    Tony, See my post on K. deusta on Acer.
  24. Fungus
    So do I, so I suggested it could be I. hispidus.
  25. Fungus
    Could be, could also be Heterobasidion annosum. To be 100 % sure, wait for the FB's to show up.
