Back at work, but not climbing or surveying for a while yet.

Baby pfeiffs and adjacent applanatums on a neighbouring Authorities Beech.

Monkeyed, are we certain that root bracket is G resinaceum?

Agreed, it's not quite the typical form.

What would you suggest hama?

Well it is a difficult call, photos make it tricky, and laugh at will but it looks a bit heterobasidion to me

[Tony Croft aka hamadryad]

Its funny cos I came a cross the exact same form on a dead birch root yesterday, I will put a good wager on this ID, the foresters favourite root rotter

Not laughing atcha mate so much as postulating in public....! It will come as no surprise to learn that annosum root rot occur preferentially on conifers....It has been recorded on as many as 200 different hosts over the years. The one thing which is I think significant is the fact that infection on broadleaved hosts is likely associated with widespread infection within a locality. This because the mycellium is not able to propagate great distances in the soil, preferring root grafts as infection courts. Economically very significant ( forestry). Check out this tho'

lol, i wouldnt mind if you did laugh! It is Bassidium, no doubt, this is an unusual shape for it, but have seen it and many forms of fungi display a full circular fan when on surface roots. The close air contact makes it fruit on these areas and I have a great one of the oyster coming off a surface root at kew, most untypical of the species shapewise

Would folks agree that this is most likely G. pfeifferi? There were FFBs in two locations - the larger on an old stem wound at around 6m and the smaller one in the main fork of co-dominant stems at about 7m. The shadow on the second picture makes it hard to see properly. I don't remember seeing this before - mostly Fomes fomentarius above ground level on Beech.
