Correct if you add that on top of this Catalpa has to compete for resources provided by the endomycorrhizal symbionts with the grasses and herbs too and because it's an exotic species it doesn't effectively keep them out of its territory by producing a leaf and litter layer covering the soil.

Ben, Checked the pH ? If the soil is very acid, it could be a site where pioneers like birch, willow and maybe scotch pine can naturally associate with an ectomycorrhizal symbiont such as Pisolithus arhizus. And alder is a good choice too, because apart from the tree species specific Frankia alni bacteria, it has its own ectomycorrhizal symbionts of the genus Alnicola, some of which alder also shares with willows.

Geoff, I think they do that for another reason : for a deeply felt insecurity and anxiety that what they have been taught to believe in and hope for - HEAVEN - will turn out to be a hoax in the end and because of that they want to be reassured over and over again that they don't stand alone as long as there are a lot of other people out there believing the same thing. And maybe that's why atheists are not on the look out for other atheists : they have no need for confirmation of the non-existence of gods or whatever is "up there" looking down on us, because gods are made up by men and don't exist.

I have a simple question : why is it always christians asking whether there are other christians around and never atheists looking for other atheists to share their ideas with ?
-
Also look for Tubaria furfuracea, Pluteus romellii, Agrocybe praecox and A. rivulosa and Volvariella gloiocephala.
-
Simultaneous white rot without the mycelium of at least one saprotrophic macrofungus causing it (without fruiting yet) ???
-
I agree, because Catalpa is associated with cosmopolitan generalistic endomycorrhizal microfungi, that also associate with grasses and herbs and are unable to provide powerful tree root defense systems.
-
David, This looks like a last years annual Inonotus dryadeus, not like a perennial Perenniporia.
-
Sean, No problem, I'm in ... out I mean .
-
The bracket fungus could well be Oxyporus populinus, but a microscope is needed to determine these specimen with 100 % certainty.
-
Gollum, I've seen this type of failure with residues of white mycelial felts coming from Grifola frondosa.

A photo of sap on the move down the remaining stump of an old, but healthy birch that has been cut two weeks ago without any good reason at all. ---

Matt, Third photo to the far right : Hypocrea pulvinata fruiting from and on its white mycelium covering the pores and penetrating in the tubes.

Jonny, When they're fresh, sure, but not when they're this old .

Felix, At first the mouse was accompagnied by a robin that was so afraid of the mouse that he kept quite a distance from him. While I was looking for my camera, the blackbird came and chased the robin away. The mouse ignored the change of birds completely and the blackbird seemed to be too puzzled with this beviour to even consider attacking it while the mouse ran back and forth to its nesting hole to store the sunflower seeds available. This went on for more than ten minutes until the mouse had taken all the seeds as you can see in the first photo that was taken after the second. In the following photo you can see how the blackbird even reacted disturbed on the sudden movements of the continuously returning mouse. ---

Tony, Might be an Antrodia species such as A. serialis.
-
Guy, And while you're at it, could you also enlighten us on the mitigation of the risk of an old birch decomposed by F. fomentarius ?
-
Not very exceptional, a blackbird in one's garden, but this combination of one of the wood mice living in my back garden competing for food with a male blackbird is something worthwhile sharing, I guess.

Hamadryads diary- a new chapter
Fungus replied to Tony Croft aka hamadryad's topic in Fungi Pictures
Tony, Although a bit oversimplified . I'm familiar with her work, which is mainly on Pseudotsuga menziesii and Betula nana, both tree species I have left out of my book on the tree species specific ecosystem concept, because they're both not indigenous in The Netherlands, i.e. the Douglas-fir not in Europe and the birch restricted to the European alpine zones. -
Nick, The effect of this Fomes strategy is not that the life of the beech is prolonged and parts of the crown remain healthy, but that the tree gets far more at risk of loosing a part to one half of the crown and stem because of a vertical split caused by a (summer) storm, especially when the tree is in full foliage and Fomes has formed mycelial sheets or felts inside the vertical split zone. ---
-
David, Brett & Gollum, Would it be possible to have your Gano's microscopically identified, because this far I've only found G. australe on Eucalyptus, which by the way is not that exceptional in The Netherlands.
-
Guy, So on what Leg does your hypothesis on one of the many other pathogens including Phytophthora to be responsable for the black oozing stand on then ?
-
Pete, The sporophores revive easily and soon restart sporulating after a frosty period, because they contain a kind of anti-freeze called trehalose.
-
I know of no in vivo experiment that has succeeded in doing that and if I thought it could be done succesfully within a life time, I would have started experimenting myself several decades ago. IMHO it's as with planting trees, we plant them four our children's grandchildren without ever knowing whether they will appreciate or follow up on what we've been trying to pass on to them.
-
Sorry for being so pessimistic, but it has taken me half a lifetime to understand a tiny bit of what is going on in tree species specific ecosystems and soil food webs and how they are influenced by men and other factors and I'm still learning every day. Even while writing a book on the subject, I still hesitate to claim having any real and practical knowledge of mycorrhizal fungi and the role they play in the dynamics of the life cycles of trees.
