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

[Arborowen]

Been a while since I've posted on here and equally feels like an age that ive actually had to ID a fungi being that the majorty of work presently appears to be BS with a lack of mature defective trees.

 

Anyway. This white spored fungi on an oak is foxing me. Its likley a usual suspect but can think which. The shape and spore colour is wrong for ganoderma? and the cross section does not match other brackets such as ridgioporus.

 

Your assistance here would be much appreciated.

 

Thanks in advance.

Would ypu beleive me if I said that was my first guess. :-) with the form and white spores. The cross section seemed a bit too brown though. Ok. Thanks David. Do you have any comment on the significance on oak. Maybe not as dramatic as ash?

From my experience I have found that association not as significant as that of P. fraxinea and ash, although your example (due to the size of fruitbodies) does look like a long term colonisation.

 

Have you carried out any decay mapping?

Spindle shank (Collybia fusipes) here fruiting on the buttresses of this sessile oak and not from the sinuses from between the buttressss.

 

Canopy still full of vigour, though just shed a large lower lateral branch.

Long time colonisation of Inonotus hispidus on weeping ash.

 

Canopy gets a hair cut every now and again.

Mycorrhizal Amanita rubescens (the blusher) possibly fruiting where the mycelium is collecting the water run off from the bark.

Yep, rigi

 

Any plans for the tree?

Yes well that's he tricky one. I've been asked to re inspect three HCs following a comment by a knowledgeble member of the public. The tree with the rigi is not the one they are concerned about. They're seeing scaring from bleeding canker and getting anxious on another tree which is further and weighted away but still close enough. This one with the rigi had 2 mtrs out top only in 2014 leaving the entire remainder of crown toward play area. Previous tree office denied permission to carry out 6mtr height reduction specd by previous consultant. Which now I've met the trees can see would have been overkill.

 

My initial concern before the rigi on this was the historic dog legend prunnig wounds common on HC when low branches are heavilly prunned back.

 

Plenty to think about. Not sure of significance of the fungi. HC is fully on my one to watch list given its tendency to lack much warning signs or indicators in foliage vitality and to be peppered with bleeding canker often making things look pretty break but might not be. Very difficult to judge much beyond these two factors using just VTA.

 

Any thoughts? I've done several HC jobs this year all with the same collection of issues. Although not quite on this scale.
