David, The first one's (again) to young to be sure, it could either be a Trametes or a Bjerkandera species still developing. The last one is either Stereum gausapatum or S. rugosum, both species turn red after scratching the lower surface with a finger nail.

Scott, Thanks, valuable documentation . Did you in this case and all other mentioned cases - especially on beech - check the spores microscopically to be 100 % certain of G. australe and could the small sporophores near the ground on Eucalypt be diagnosed as panic fruiting ?
-
According to the British database, there's one registration from the U.K. under the currently valid name of Hapalopilus croceus.
-
Scott, How much experience do you have assessing the extent and severity of the white rot with selective delignification caused by Ganoderma australe in tree species such as Aesculus, Platanus, Acer and Tilia and did you (always) use a resistograph to verify the data of tomography ?
-
Douglas, As I already said in a private message, Picus scans do not produce reliable in situ data on the extent of white rot with selective delignification caused by Ganoderma species, even if you repeat them after some time.
-
It is a Mycena and this time of the year it might be M. tintinnabulum.

Documentation of Ganoderma lipsiense on an Abies stump. The coniferous mulch surrounding the stump is decomposed by Clitocybe gibba. ---

Tobias, Although the link has no documents or articles attached to it, I can tell you this : yes, it first was identified as G. lipsiense by a German "expert" from a photo, again identified as G. lipsiense by a Dutch mycologist looking at the characteristics of a bracket, then identified by me as G. australe by looking at overview photo's of the tree with over 20 perennial and panic fruiting annual brackets, which are indications of a biotrophic parasitic macrofungus at work and confirmed being G. australe by another Dutch mycologist looking at the spores.

Tony, Although you're spoiling Sean's quest for the name of the species, his mystery tour ends here, because you're right : it is the facultative ectomycorrhizal Paxillus involutus in its temporary saprotrophic phase.
-
In The Netherlands, along with Quercus rubra and Q. robur brown rotted by Laetiporus sulphureus and/or Daedalea quercina or white rotted by Phellinus robustus.

Some pictures of my recent revisit to the partially still moving sand dunes of the Dutch national reserve Kootwijkerzand. 1/2/3. Natural standing up and laying down monoliths of Pinus sylvestris. 4. Natural monolith of P. sylvestris with young Quercus robur at its feet. 5/6. Root system of P. sylvestris growing on top of sand dunes. ---

A "Fly Agaric" bird feeding table attached to a tree in a mixed forest in the middle of nowhere and miles away from urban settlements in the German Eifel. Who's feeding the birds, the dryads and gnomes ? --
-
, because in that way you stop the competition for endomycorrhizal symbionts of the (reviving) tree rootlets with the roots of weeds and grasses, so the tree can keep all the nutrients uptaken and delivered to the roots by the mycelia/hyphae of the microfungi to itself.
-
Might be Pisolithus arrhizus (= P. tinctorius), which also is an ectomycorrhizal species. So Sean, Could you cut a specimen in half to see what the inside looks like ?
-
1. Not just investigate the tree on soft rot on the lower sides of the major roots and white rot inside the roots and buttresses, also look at the white and soft rot at and below ground level in the base of the trunk and in between the buttresses before you advise on retrenchment or pollarding of the crown or felling of the tree. And look for superficial adventitious rootlets surrounding the tree base in combination with die back of the central crown indicating the tree has entered its final reproductive phase. See my MTA case study. 2. No, there is not.
-
David, What species do you suggest ?

Tis the season to see Fungi, fa la la la la....

Nice shots , especially of the Gr on Hornbeam and the Fs on Oak. -

Tom & David, There is, and there also is a connection to the very late falling of the leaves (and nuts : mast year) triggering the trees to withdraw the chlorophyl from the foliage, store some of the sugars in their roots and sharing some with the Laccaria mycelia surrounding the fine superficial roots with their ectomycorrhizae. The pictures in my thread were taken last Friday too and there were thousands of FB's in the drip lines of the tree's outer crown projections to choose from.
-
David, 1. Colonising the outside of a trunk and rising up from the roots, rhizomorphs mostly are of a necrotrophic parasitic Armillaria species, that killed the living tissues while shedding the bark in the process. 2. If they go all the way to the ground, it could be adventitious rootlets from a tree too, but to be sure you'll have to break the brown tendrils : brittle and white hyphae inside ==> rhizomorphs, tough and longer yellowish fibers inside ==> rootlets.
-
Stevie, Needle blight present ? If so, Phytophthora cinnamomi ?
-
Sean, Is it Scleroderma citrinum ? If it is, it can be saprotrophically decomposing dead wood or be associated with some tree species other than Acer as an ectomycorrhizal symbiont.
-
As Sean already said, not necessarily. Inform yourself on the topic by reading the (latest) posts on the Meripilus thread.

Tom, You didn't have to bother to visit the woods, you could have stayed inside and have a look at my Beech & Laccaria amethystina thread .
