You might want to consider re-potting (or planting) it & adding new soil with organic mix, as it looks to have run out of resource for its roots. It will be stressed in this condition and open to attack from various pests and disease.

Ganoderma adspersum will associate with a wide range tree species. The spores of the fungal fruiting bracket on this Eucalyptus will be everywhere in this and the neighbouring garden and could/will recolonise any tree host that is stressed or damaged. So, it's perhaps not really a question of which tree species to replant with but more one around protecting any new tree from damage (mower, strimmer, compaction, fencing etc...) establishing it well and and keeping it healthy (access to good un-compacted free draining soil, water & full sun light) Sounds like this tree probably should be removed and replaced with a different species due to the use and size of the garden. My experience of Ganoderma and Eucalyptus in (sub-optimal growing environments) is not good, the mycelium will remove most of the lignin in the heart of the tree and eventually impact on the residual wall strength. This one failed in a pretty strong wind, but was probably only a question of when.

Chicken of the woods, (Laetiporus sulphureus). Brown rot decayer.

It does look a bit like Sparassis although Fuligo (and its closely associated myxos) can look like this and many other forms as they are quite variable.

I think the first image are different stages of the slime mould Fuligo septica.

I thought it was a very good webinar, the three panellist spoke well and John compared it with skill and panache ☺️ Some of the questions were a bit lame mind 😉

Grifola frondosa is an unusual association with birch. I've noted it on other tree species (Robinia, hazel, cherry) as well its main host (oak) but don’t recall seeing it with birch. Although I have read that it can be a host association, and have seen a record of this. Do you know if there evidence of it being G. frondosa? Just interested. If it is, then it is likely to be evidence of root dysfunction and associated white rot decay of some/all of the roots of the tree, possibly caused by root fracture via a strong wind event or below ground damage from utility excavation. Has the tree been tested in any way? Visual assessment during root excavation, decay drill, pull testing? Again, just interested in the tree inspectors methods.

Looks like a slime mould - false puffball, (Enteridium lycoperdon) Feeding on dysfunctional wood volume.

Ta, most are from files, couple of them more recently.

You've been tango'd ! Orange....ish fungi L. sulphureus I. hispidus F. pinicola P. adiposa T. ferruginosa Slime mold A. aurantia Bacterial slime flus Cheilymenia spp R. epindendron C. perennis G. sabinae L. aurantiacus F. hepatica S. scutelatta A. muscaria var formosa S. aurantiaca T. mesenterica F. velutipes C. viscosa P. aurantiorugosus

The picture is of the Dexter Elm in 1894 Massachusetts, controlling Gypsy moth

Any images?

Nice find

Thought you’d find it of interest. 🙂 I’ll pop back later in the year to see if there are any localised bleeds.

Five years on.......
