    In the case of annual necrotrophic parasitic species, no, but in the case of annual biotrophic parasitic species, such as P. squrrosa and M. giganteus, yes !

    ... or a few clumps of large well nourished fruits producing just as much or even more spores as multiple small groups of small malnourished form, which also can be a way of panic fruiting. Besides, the volume of well nourished large FB's is coming from just as much or even more decomposition of dead wood as is needed for producing the volume of multiple small groups of malnourished FB's.

    Sloth, 1. What shroom on what birch stump ? 2. Some ascomycetes - especially the Pyrenomycetes or Sphaeriales - do, some don't. In this case, both Ascocoryne sarcoides and A. cylichnium can be the teleomorphs of the anamorph in the picture, two species which can only be identified with a microscope.

    Scott, I have seen old limes (willows, poplars) being windthrown or split in half by P. squarrosa with outer signs of decay such as a basal flare and/or with (first time) panic fruiting of this biotrophic parasitic fungus.

    Mark, The best method to cultivate tree seeds in tubs is letting them germinate in a handfull of the top layer of forest soil from the woodlands the tree species originates from mixed with the "normal" compost to give them a quick start by associating with pioneer ectomycorrhizal symbionts (oak, beech, hornbeam, sweet chestnut, hazel) or endomycorrhizal microfungi (Acer, Aesculus).

    Leucoagaricus leucothites.
  7. Fungus
    Rob, Correct , the red one is L. ceres (= Stropharia aurantiaca) and the greenish blue is S. cyanea (= S. caerulea). Without information on the stipe, gills and spore colour, the white one can't be identified.
  8. Fungus
    1. On calcareous soils in grasslands and it has different spore sizes, so the characteristics of the stipe and the colouration of the cap are not decisive. 2. I'll ignore that .
  9. Fungus
    Gollum, 1. Xerocomus (= Boletus) badius ? 2. Milkcap in beechwood ? If so, Lactarius pallidus 3. Daedaleopsis confragosa 4. Clitocybe clavipes ? 5. Geastrum triplex 6. mould on Bolete 7. Stropharia cyanea ? 8. Mycena polygramma ?

    Tony, Did you exclude Coprinus stanglianus ?
  11. Fungus
    This small and between grass outside beech wood ?

    From the pictures alone, I can't decide whether it's M. rachodes s.s., M. bohemica (if it does exist) or M. olivieri, which also is a candidate if your Shaggy Parasol was found in a coniferous forest. And after I had a second look at your last pictures, I even doubt it's M. rachodes, because the stipe has the characteristics of M. procera, and M. rachodes doesn't get that big, so did it turn reddish orange when bruised ?

    David, 1. In the Dutch 1981 edition of Phillips' Mushrooms and other fungi of Great Britain and Europe, all information on edibility or toxicity of fungi, including Macrolepiota species, is left out. So does Phillips also depict and describe M. bohemica or M. rachodes var. hortensis and M. (rachodes var.) olivieri in his latest English edition and if so, what does he say about their edibility as compared to their look-a-like (or the identical) M. rachodes ? 2. Of course you don't, I just warned for the risks of eating reddish orange bruising Macrolepiota rachodes s.l., including M. bohemica (= M. rhachodes var. hortensis), which in my opinion and some other authors (E. Vellinga, Flora Agaricina Neerlandica, Volume 5, page 72), is identical to M. rachodes s.s. Last year, some German Eifel friends were sick for two days after eating Macrolepiota rachodes s.l.

    As you can see in the picture, it's cap has already started "decomposing" and blacking the gills and the rim of the cap by riping spores and in that phase lots of smaller Coprinus species have lost their scales entirely. Besides, it looks wet from rain or fog, which makes microscopical identification impossible because of the lack of velum. To microscopically identify smaller Coprinus species, you need FB's in all stages of development.
  15. Fungus
    David, Do you intend Toby to get sick ??? Macrolepiota bohemica (= M. rachodes var. hortensis), which is not much different from or identical with M. rachodes s.s., is on the warning list, because it can cause stomac pain and indigestion problems.
  16. Fungus
    Scott, As you will have understood from my threads, for evidence of either G.australe or G. lipsiense being the pathogen, in quite a few cases microscopical identification is necessary. Couldn't there be an identification service by a mycologist or institute like the service I rendered, organised by the AA and/or ISA for their members ?
  17. Fungus
    The name Aurantioporus originally was given to species with orange golden pores, that became whitish because of the white spores. Now A. croceus has been reclassified as Hapalopilus croceus and the entirely white to grayish yellow A. fissilis is still classified under the old name, though is has no orange golden pores at all.
  18. Fungus
    Rob, 1. Turns purple with caustic potash ? If so, Hapalopilus rutilans 2. Ganoderma cf. lipsiense 3. Trametes versicolor 4/5. Lepista nuda 6. Xylaria hypoxylon + Pholiota lenta 7/8/9. Trametes gibbosa 10. Psathyrella species 11. Lepista nuda or L. personata ? 12/15. Hygrocybe miniata 13/14. Agaricus vaporarius ?
  19. Fungus
    Sloth, Maybe Leccinum melaneum and the little one is a Psathyrella species.
  20. Fungus
    1. Clitocybe gibba 2. Coprinus plicatilis s.l. 3. Coprinus species 4. Oudemansiella mucida 5. Melanoleuca species 6. Lepista nuda 7. Grandinia/Cerocorticium/Steccherinum/Mycoacia species : microscope. 8. Tephrocybe species 9. Xylaria longipes (Acer) ? and in background Mycena species 10 Arcyria/Stemonit(ops)is species ? 11. Coprinus comatus 12. Macrolepiota rachodes var. hamadryadoides
  21. Fungus
    No idea, I can't look through the camera lense from here and it is too small to be visible in the photo.
  22. Fungus
    To me it looks like he's rubbing his eyes, cause he can't believe what he just saw .
  23. Fungus
    No, with (yellow) golden pores, aurum = gold.
  24. Fungus
    Tobias, Why don't you go look for Hapalopilus croceus yourself ? According to Ryvarden & Gilbertson, it should be present in your region, i.e. north to the soutern part of Sweden. In Denmark and Norway, however, it should respectivally be extinct since 1937 and 1880. Speaking of nutters. I've lost count of the times I was asked whether I was sick and needed a doctor by people confronted with me photographing fungi while lying flat on my belly in the woods or having dogs climbing on top of me wanting to mate .

    Amazing , the biggest number of "pica's" I've ever seen at one time is three ! Must be quite some beechwood too.
