    Nice one , better than the huge trifold specimen, I found yesterday fruiting from a large wound at the base of an old beech. It was a pity it was rather dirty from rain running down the bark of the trunk. ---

    It's German for "branch crawler or creeper", which means that the FB's grow as a resupinate layer on the lower side of the branches starting from the branches' attachment to the trunk as is shown in your first and third photo.

    Tony, and I add my yesterday's find on an old, severely damaged oak. ---
  4. Fungus
    That someone was me, and I said it was not an Armillaria species with white spores, but Coprinus micaceus sensu lato, including other Coprinus species such as C. micaceus s.s., C. pallidissimus and C. truncorum, with black spores. And if you want to be 100 % sure, you'll need a microscope and specialized literature on the genus Coprinus (see Kees Uljé : keys to the subsections of the Coprinus species).

    Phellinus punctatus is saprotrophic and mostly fruits from branches with soil contact, so this probably is (an Astkriecher of) the biotrophic parasitic P. igniarius.
  6. Fungus
    Also see this example of a small, but complete FB of Melanoleuca cinereifolia fruiting on top of another fully developed FB. ---
  7. Fungus
    Scleroderma citrinum fruiting from dead roots, that before had been surrounded by ectomycorrhizae from the same species, after the oak tipped over. ---

    Could be, the Genus name Daedalea refers to Daedalus, who for king Minos designed and built the still present labyrinth of Knossos (Crete) with the bull Minotaur guarding it and together with his son Icarus escaped from it using sticks, wax and feathers to make wings from. According to the myth, Icarus flew too close to the sun, the wax melted and he drowned in the Aegean See.

    1. The genus Dothistroma or Mycosphaerella also is a (ascomycete) blight colonising all kinds of plant or tree leaves and needles. 2. No, not to my knowledge.
  10. Fungus
    Yes, many species of fungal plant pathogens with low genetic diversity, such as patato and chestnut blight or Dutch elm disease, can. See the article in the nature journal.

    A nice example of the phenomenon of a reversed cap on top of another cap of Laccaria amethystina, I found yesterday. It only happens when the FB/cap coming from the primordium of the upper (stipeless) FB is attached to and lifted up by the lower FB while "stretching" from its own primordium connecting the upside down cap with the originally shared mycelium through the cells of the cap of the lower FB and making development of the also fertile spores producing small cap possible. ---

    ... like this prolific annual and perennial fruiting I found yesterday on a stump of Q. rubra ? Great pictures , especially the last one. ---
  13. Fungus
    David, No, it's always on the (sterile) top of (perennial) Daedalea quercina without colonisation and deformation of the fertile maze gills, which differs from H. rosellus' strategy on annual Polyporus species, that it decomposes before fruiting with teleomorphs. The bracket in the first photo had its "gills" consumed by (larvae of) insects leaving their droppings behind on the oak trunk. The second photo shows the first year fruiting of the mycelium of D. quercina with H. rosellus already on top. ---

    Tony, 1. The question was meant for Guy and as your answer is incomplete, maybe he can elaborate on and add to it ? 2. No, I. cuticularis is a soft rotter of living tissue and a simultaneous white rotter of dead wood.
  15. Fungus
    Yesterday, I found several brackets of Daedalea quercina infected with the pink to purple mycelium of Hypomyces rosellus. ---

    ... could also be the result of "hammering" on trees to communicate with other woodpeckers on the bounderies of their territories.
  17. Fungus
    1. Pores of A. croceus, which have turned from bright orange-yellow to whitish by the ripening spores. The flesh is saphron yellow. 2. Pores of P. cinnabarinus. The flesh has the same colour and the mycelium colours the white rotted wood vermillion red. ---

    Marco, I know, that's why I dedicated these colourful beauties to him in the first place .
  19. Fungus
    Yesterday, I returned from a three day's field trip to the beech woodlands and mixed forests of the northern parts (Hulshorst, Leuvenum) of the Veluwe. Lots of Pycnoporus cinnabarinus about and 5 annual brackets of the extremely rare Aurantioporus croceus, which is a first find for The Netherlands and the Flemish part of Belgium. The two FB's on the saw cut of the felled birch were accompagnied by the transitional phase from plasmodium to aethalium of the myxomycete Fuligo septica var. candida. ---

    In The Netherlands, there have been two periods of fruiting, end of July untill the end of August (especially ectomycorrhizal symbionts) and the past two weeks of October. And apart from lack of soil moisture, mycelia of terrestial macrofungi don't fruit when a drying wind "hits" the forest floor. I've often watched mycelia sticking up tiny white, yellow or red flags to test the dryness caused by wind before they decided to start fruiting .
  21. Fungus
    Armillaria species have white spores, this is the saprotrophic Coprinus micaceus s.l. with blackish spores, that prefers dead wood at trunk's bases that dogs have urinated upon.
  22. Fungus
    Al, 1. As has been suggested by others, it could either be R. ulmarius or P. fraxinea. If it was found on the continent, it would be the last one. 2. Could also be Phellinus pini (microscope).
  23. Fungus
    Sloth, IME, they sometimes - not often - do, and the root flare can also be caused by other root degrading parasites such as Pholiota squarrosa, Gymnopilus junonius, Collybia fusipes, Abortiporus biennis, Grifola frondosa or Polyporus umbellatus.
  24. Fungus
    Andrew, or other insect larvae. Woodpeckers only create one or two holes for nesting (see : the arborists little helper).
  25. Fungus
    No, with beeches sometimes die back of the central crown and development of adventitious roots surrounding the trunk's base with Laccaria amethystina fruiting from them and panic fruiting (see photo) of Meripilus after the tree fell. ---
