    Charlieh, Read : 1. Succession of saprotrophic macrofungi, 2. Endo- and ectomycorrhizae and 3. the pine, beech, alder and birch specific ecosytems macrofungi thread, to get a general idea of natural forest ecology, tree species specific ecosystems and their tree species specific soil food webs including tree species specific saprotrophic and ectomycorrhizal macrofungi.

    It's a lot more than that : 15.000.000 : 7.855 square centimetres (500 cm x 15.71 cm : being half of the circumference of a branch with a diameter of 10 cm and a radius of 5 cm) = 1.910 spores of circa 8 µm pro square centimeter, meaning there still is 0.85 square cm of spore free surface per square centimetre left. Also see the amount of spores produced by a FB of Polyporus squamosis.

    Some rare finds, that were shown to the participants of the field trip following yesterday's mini-symposium on the Tree Species Specific Ecosystem in Maastricht. 1. About 35 years old Fomes fomentarius on Aesculus. There were 10 perennial brackets of Fomes in total on the trunk of the recently heavily pollarded tree. In the most southern region of The Netherlands, Fomes fomentarius is mostly found on Populus and Aesculus. 2. Inonotus cuticularis (notice the unfinished woodpecker's hole) on a beech, that also had very small panic fruiting of Meripilus giganteus at the trunk's base. One half of the bifurcated tree meanwhile had died and was covered with FB's of Diatrype stigma peeling off the bark. 3/4. A young FB and older vandalized FB's of Ganoderma pfeifferi on the trunk's base of two grafted "notary" beeches. ---

    This time last year the fruiting was much better, this year two to three weeks ago, the fruiting was much more prolific compared to the same time last year.

    Tom, As long as rhizomorphs of a parasitic Armillaria species stay behind in contact with remains of living roots of the removed tree(s), the chances of re-infecting the roots of new planted trees are very high, because rhizomorphs can detect the growing hormones of damaged tree roots of trees coming from a nursery from a distance of one metre and grow towards them with a speed of up to one metre a year. So the best policy would be to dig out all remains including all major and minor roots of the removed trees, exchange all of the infected soil with new soil and wait one to two years before planting new trees after no (panic) fruiting of Honey Fungus from overlooked remaining roots has taken place.

    No, I never do and never use flash light either. These photo's were taken handheld with my Canon PowerShot SX230 HS digital camera.

    Tony, The most important thing is to monitor and document a forest/woodland plot or an individual (veteran) tree and its tree species specific ecosystem(s) during at least 10 to 15 years of its life cycle, before first conclusions can be drawn.

    This afternoon I returned from a three days trip to the German Eifel where I monitored some of the plots I have been visiting monthly during autumn for 8 years in a row. Photo 1/2. In an old beech woodland on partially buried beech wood : Agrocybe firma, my first ever find of this rare Red List species. Photo 3. In a mixed woodland with oak, hornbeam and hazel : a common species on thin branches and twigs of deciduous trees : Marasmiellus ramealis. Photo 4. In a spruce forest noticed from quite a distance at the damaged base of an old spruce : Ptychogaster albus, the anamorph of Oligoporus ptychogaster, with guttation droplets. ---

    By gathering lots of data from in vivo or in situ research.

    This is only true for bonzai trees of tree species associated with ectomycorrhizal macrofungi, which is the minority of bonzai trees.

    Dave, I don't think so, as the spores of the anamorphs of Massaria, that are only a few µm in size, are spread top down through the inner crown by wind, rain and water dripping down on the below branches, which explains, why the lower branches are infected/affected the most. In Cologne (Germany), researchers counted about 15 million of these spores over 5 metres length on the upper half of a lower branch with a diameter of 10 centimetres.

    Sloth, Yes, but just as characteristic of Pholiota squarrosa on Platanus.

    Tony, Although I have my doubts on the validity of this type of in vitro research, I can confirm your conclusions, because according to Ryvarden & Gilbertson, both G. australe (if microscopically checked !!!) and G. resinaceum are only documented fruiting from living trees.
  14. Fungus
    Marco, This must be the case, as Armillaria gallica (= A. lutea/bulbosa/cepistipes) is a saprotrophic Armillaria species only capable of decomposing dead wood, which also explains why the black oose must come from the Phytophthora.
  15. Fungus
    Ben, Don't show the Chinese inhabitants of your country where they can find it, because they pay a lot of money for a meal with a fresh "Ape's head" or pom pon blanc, that is also know for its medicinal qualities.
  16. Fungus
    The guy or woman must have very special eyes then , because with this a-typical specimen of an annual and not yet fully developed Ganoderma species on oak, I would need a microscope to identify this species as either G. resinaceum or G. lucidum .
  17. Fungus
    Marco, I'm still not convinced, that your pictures from the base of the willow depict Clavulina coralloides, so my request would be to go back in a week or so and photograph what has developed by then.
  18. Fungus
    Marco, Or Ganoderma lucidum ?
  19. Fungus
    David, : Laccaria laccata s.l. (incl. L. proxima), an ectomycorrhizal pioneer symbiont associated with the primary roots of young trees (seedlings) or the fine roots of older trees.
  20. Fungus
    Marco, That was Clavulina coralloides, not a Ramaria species, see my earlier reply.
  21. Fungus
    Marco, I can't remember, which Ramaria you mean, but most Ramaria species are ectomycorrhizal and don't grow on (living or dead) wood.
  22. Fungus
    Nice footage, especially the part about plant intelligence, but not a word about (the ecosystems of) trees total dependence on fungi as a whole and on mycorrhizal symbionts in particular.
  23. Fungus
    Marco, I agree, I expect this will turn out to be a fungus growing in a bundle and with caps and gills such as a Lyophyllum species or a poroid annual bracket fungus such as Polyporus umbellatus.
  24. Fungus
    Pete, It can't be Phellinus robustus, because that's a biotrophic parasite, so it probably is the saprotrophic P. punctatus .
  25. Fungus
    Volvariella gloiocephala (= V. speciosa).
