Fungus

Andy, 1. It certainly is if one looks a bit further than the tree itself and sees the very complicated and rich tree species specific ecosystem even a dead tree represents. 2. Felling and removing this tree would implicate the destruction of a complete habitat for hundreds of insects and some mammals - including bats -and birds or other animals depending on the tree for food and reproduction and needed for the survival of lots of macrofungi by enabling fruiting and dispersion of spores to colonize new trees, because dead trees are stepping stones in the (natural) landscape.

Fomes fomentarius is known to form whitish mycelial felts.

White rot, that can be caused by a number of fungi living in/on birch. In this case it might be by the endofyte Fomes fomentarius.

Sloth, Correct, in this case with just one species' mycelium present, the black lines are not of a fungal origin, but produced by the tree itself as a barrier to keep the spreading of the hyphae and the soft rot restricted to "walled off" parts of the heart wood and prevent them from using the starch rich radial rays as a "highway" to get to the living tissues and then to the outside for fruiting.

Matthew, 1-5 : Bjerkandera adusta 6-8 : Resupinatus applicatus 9-17 : Calocybe gambosa

Bjerkandera adusta is a saprotrophic white rotter decomposing dead wood with polyaromatic hydrocarbons. On beech, B. adusta is often succeeded by Trametes gibbosa, a parasite that kills the mycelium of B. adusta before it starts decomposing wood itself. ---

Andy, Every time I pass this "ivy" oak, I enjoy looking at it and thank the farmer for not felling it, although it is "cluttering up the view". ---

On scots pine ?

Criminal behaviour IMO. In The Netherlands vandals set fire to one of the nicest old hollow Castanea's, called the kabouterboom (pixie tree), that luckely escaped from burning down to the ground because of a timely intervention.

"I reread that they are next to roads, and not always next to farms, but near enough to be affected by nitrification. So you're conclusion is based upon the removal of three trees at a roadside and not always, i.e. in reality hardly ever next to farms and you qualify that as forestry instead of arboriculture ? How near is near enough for trees to be affected by nitrification from extremely overpopulated pig and chicken farms and extremely manured maize fields : one kilometer, five kilometer, fifteen kilometer ? What density of farms and fields is needed ? One per five square kilometer, five per twenty square kilometer ? And nitrification travelling by air or by (surface) water ?

No criticism intended, but I've seen several hundreds of annual brackets of both B. adusta and B. fumosa over the last 35 years and these specimen have no macroscopical characteristics of B. adusta at all. But to be 100 % sure : microscope.

Nice find . In The Netherlands both Coriolopsis trogii and C. gallica mostly grow on poplar and C. trogii sometimes is found on beech.

No, because of the colour of the pores : Bjerkandera fumosa.

1. Now who would say anything like that? Silly talk. If the reliability of your documented observations was evaluated by scientific standards, your work would not stand for anything at all. Just consider how often "documented observations" have been proven invalid (overgeneralisation based on (a few) poorly documented and not standardized single case studies) and identifications of pathogens and their supposed effects on trees these obervations were based upon also have been proven wrong. 2. When and where did I prescribe "cutting and grinding for trees next to farms" ? So you're the "meilleur Guy" and I'm the bad guy ? Putting words in my mouth and citing me completely out of context and without understanding the problems we face with nitrification does not compensate for the lack of reliability or relevance and proof of your opinion.

My Interactive Guide to Mushrooms and other Fungi in Dutch. For those who want to see photo's of a species, look it up in the list of Latin species names.

1. "Several publications describe treatments in both orchards and landscapes. Not MY methods; practiced by many. Are they in journals, no, but they reflect real events in the field, as do the anecdotal observations of arborists of compartmentalization after exposure." Now you apply double standards for the scientific quality and standard of your work in the US and my work and that of many others in Europe. By the way, orchards are ecological deserts with solitary fruit trees that have no tree species specific ecosystems or soil food webs at all and only associate with super generalistic endomycorrhizal symbionts. Did you ever see a woodland or forest dominated by or completely consisting of Malus or Pyrus ? 2. "Managing forests as you describe is a different scope" That depends on how you look at a tree. If you consider it to be an isolated solitary organism not in need of a tree species specific ecosystem and soil food web to survive and thrive in an urban or rural environment, then you're right.

What if on top of the unidentified desicated Armillaria, the presence of M. giganteus, K. deusta and/or P. squarrosa is assessed on the died roots or in/on the buttresses or trunk base ?

No, and too much desicated to even be sure it is of fungal origin.

1. Could be both the anamorph and teleomorph phase of K. deusta, but could just as well be one of many other look-a-likes : microscope. 2. . 3. Hypholoma fasciculare or H. capnoides.

Tony, I forgot to mention the problem of planting trees with damaged roots after having been uprooted from the nursery, of which the secretion of growth hormones is detected by alive and still to infected roots attached Armillaria rhizomorphs over a distance of about half a metre to one metre.

Cilla, Also have a look at my albums and my other threads.

I am, close to good old Daventria.

Daniel, I'm moving closer to the eastern parts of the Veluwe and will be living on the river bank of the IJssel.

IME for beech a too fierce reduction to avoid sun scald because of overexposure of the trunk.

The Grote Peel is a moor and bog area close to the most polluting pig farms with all birches dying because of nitrification. And the most similar to your national parks is the central area of the national park of the "Hoge Veluwe" with its sand dunes and oak, beech, birch and pine forests on still relatively poor sandy and loamy soils.
