Tom, 1&2 : Because of the height of and the fruiting from an old wound on beech : P. aurivella. 3&4 : Yes, Fuligo septica var. candida. 5 : . 6,7&8 : My bet would be on G. frondosa. Did you do the scratch test on the pores and did the pores turn black after a while/a day ? If so : M. giganteus, if not : G. frondosa. 9&10 : No, Grifola frondosa. 11&12 : Yes, being a necrotrophic parasitic, it's triggered to fruit by the monolithing of the beech. 13&14 : I think it's just an old graft. 15&16 : . 17,18&19 : Smell of bitter almonds or marzipan ? If so, Hebeloma radicosum. 20&21 : If the species is the same on both photo's, no Armillaria (white spores), but a species with rusty brown spores, could be Galerina marginata.

Tom, Great documentation of the problems in diagnosing the white rot with selective delignification of Ganoderma cf. australe in Q. rubra (and Tilia, Populus, Salix) with tomography as I pointed out before. And were any FB's present, what did they look like, just big perennial brackets or (also) panic fruiting ? In/on Q. rubra, IME it's close to 100 % G. australe.
-
Tom, 1. No galls of Agathomyia wankowiczi present ? Were the recently formed brackets attached to older brackets and positioned at a 90 degree turned level (geoptropism) ? And don't reconsider as long as you don't have microscopical (spores) evidence of this species not being G. australe . 2. .

1. It's not evidence of the spreading of the decay, it's the spreading of the killing of cambium and shedding of bark by an unidentified parasite/pathogen followed by a superficial wood decayer that is assessed. Assumptions, speculations, jumping to conclusions without assessment of the types of wood rot and identification of the fungi ("It looks the same ... I don't know that, but I do know that all those fb's are not good for stability"), not much to base a valid diagnosis on. 2. See my post. -
Guy, 1. IME ? How much (supervised) training and experience in using a tomograph as a diagnostic instrument and reading the data do you personally have then ? 2. So anyone renting or buying a tomograph and reading the manual is qualified to do the job ? Wouldn't it be better to leave this type of assessment to the experienced professionals, who also can integrate mycological expertise into their diagnosis ? 3. What aspects of arboriculture work better with mycology, but are not impossible without mycological precision ? As Marco already said : "the piece of equipment is only as good as the Guy operating the equipment."

If you really want to contribute to a better understanding of tree-fungus interactions and fungal invading and decaying strategies in trees, you will have to document your diagnosis and interpretation of "research" data at a much higher level of "advanced" assessment and can't confine to stating, that only "strength loss is what matters" without properly assessing what caused the strength loss in the first place.
-
, possibly Boletus (= Xerocomus) badius, an ectomycorrhizal fungus associated with old deciduous and coniferous trees, that have (partially) lost their tree species specific symbionts.
-
Rob, Oomycetes resemble fungi in mycelial growth and mode of nutrition, but differ from fungi, because they lack chitin in their cell walls. They are not related to bacteria, but are, together with diatoms and brown and golden algae, part of the Kingdom Stramenopila.
-
Without the presence of rhizomorphs, for the procedure to follow, see my earlier reply after 1.
-
Identification of this material is impossible, unless you use a microscope. And it could just as well be Meripilus giganteus.
-
David, According to Ryvarden & Gilbertson, G. resinaceum has not been documented from coniferous trees (yet).
-
Marco, 1. True, especially the intensive training and experience one needs and the (close) monitoring of the body language of the affected tree species. 2. ... and of white rot with selective delignification caused by Ganoderma australe in trees such as Aesculus, Populus and Salix.

See reliability of reading tomography. -
Tobias, IME, a valid and reliable reading can only be done by : - someone who has personally (visually) assessed and monitored the tree before tomographing it, - has identified the wood degrading macrofungi and the type(s) of woodrot correctly, which in this case is , - who has lots of experience with the tree species specific interaction of the fungi with the tree species - and has often seen the damage done to the tree after it had been felled.
-
Ray, Yes, it is, provided it is identified correctly and as long as it is completely white in- and outside. A warning though, the FB's can accumulate heavy metals to a toxic level. And it grows on rich soil in (manured) pastures, in orchards, road sides, parks, broad-leaved woods and shrubberies, often on recently disturbed soil or dried mud and in greenhouses, after the soil has been steamed.
-
Ray, A not that giant Giant Puffball (Langermannia gigantea).
-
David, No, anamorphs of the ascomycete Hypocrea pulvinata.

Kind request to (outside the personal realm) clarify the following questions : 1. Resembling a fruitbody meaning it still might not be a black foamy rubber fungus at all ? 2. A very superficial outside in saprotrophic pioneer white rotter such as a Stereum species (© G.J. Keizer ?) indicating ... the spread of decay and the spreading towards a similar "hot spot" node on a branch ... destabilizing branches of a tree ? And how did you assess a recent pruining wound being "attacked" by the same fungus if you didn't identify any of the fungi in the first place ? 3. What Polyporus species is parasitic and grows in/on Quercus phellos and with what effects ? -
Although I can't see the tube layer (maze ?), because of the woodpecker's whole and the tree being Q. rubra, I think it's Daedalea quercina, a brown rotter of oaks, that is a fast and invasive decomposer of cellulose in Q. rubra.
-
So would I, but only if the tree species is Quercus robur, Q. petrea or Castanea sativa.
-
Marco, Still a number of bracket fungi possible. Annual or perennial and on what tree species ?
-
1. (Again) poorly documented and without valid assessment of the effects on the condition and stability of the trees, the type of woodrot and the body language of both the trees and the fungi. 2. And apart from the tree species specific Phellinus robustus and Daedalea quercina, one could add several other co-existing wood decaying parasitic and/or saprotrophic species to the list of macrofungi on older oaks.
-
Matt, Hard to say from a photo alone, probably a Trametes/Antrodiella species.
-
Matt, Salix + panic fruiting + signs of die-back = with over 90 % certainty the biotrophic parasitic G. australe.
-
Marco, 1/2 + 6/7 : could be Phellinus pini. 3 : Armillaria mellea. 8 : Trametes gibbosa. 9/10/11 : Aleuria aurantia. 12 : colour of spores ? 13/14 : Grifola frondosa. 15/16 : barkcanker.
