The Lab stumper

We've been watching this unknown bracket for a few months.

It's on an interesting robur which also hosts both Podocypher & the Safron Bolete.

Fomes, Perenniporia & Daedalea have all been offered up (by our local little fung fraternity)

but from the ground, it was a little too hard to get a good enough look at it.

So, up I toddled to get a closer looksee & to get a slice for sending off for identification.

What is not helping things here, is the incredibally slow formation, possible abortment of archetypal form,

& also critically, a lack of a fertile tube layer.

The very helpful guys form the Jodrell Laboratory at Kew, can not help with a positive Id due to the above.

It's been suggested that Perenniporia is a potential suspect.

Mmmmmm.

Will keep an eye on it's future developement.

.

Located where it is...( & not so much the height of it actually, although it is of some significance quite possibly (? )- ) Do you think it is acting saprobically or is it perhaps more pathogenic ?

--------------------------------------------------------------------------------

I believe it to be Sapro Tim.

There isn't much in the way of external decay evident on the exposed heartwood.

Didn't probe much into it though, whilst I was up there.

The issue around identification is maily about finding out what it is, but also weighing up what it's MO is, in terms of structure/stability, right above a joint ownership/managed path.

This Tree isn't actually one of mine, but the neighbouring sites.

It's influence is above my target though, hence my offer to go looksee, not something I think 'they' would of/or had, the resource to do.

"There isn't much in the way of external decay evident on the exposed heartwood."

Certainly fits with the alacrity with which it forms! At the same time though, you are saying that you expect the decay to be concealed within the heartwood and not using sapwood?

oh- and Edit- Blimey, you took a big ol' chunk out of 'er eh!

Edit 2- Sorry mate...but which face/plane is the mazed surface?

Mindful, of staying open minded on place/type of decay.

A little bit of an optical illusion with the chunk, though I was keen to try and get a substantial slice as a specimen for the the good doctors at Kew.

The pores, oddily, are on the top of the bracket next to point of attachment.

.

So perhaps we are looking at some form of "disruption" in the formation of this specimen, or maybe species/host dynamic we are not use to associating together...?

Mmmm...Has the removal of a sample had any adverse effects out of interest`? Always with the questions huh!

Who knows

.

Yes..I see you posted "aborted archetype"...my bad!

Some kind of parasitism of the fruit body causing this maybe...another fungus perhaps even. Keep us posted.

For me, this is daedalea quercina, with very little hessitation. its got all the right features, slow to form "resting" right colours (slightly orange at times) and the pore surface if you look closer is definatley "maze" like.

i enclose a sample that i have been observing for around 3 years now, so obviously perenial. Its forming more at the moment, and will get some new images as soon as poss, interestingly this one is above a busy road, but its such a slow weak and saprobic rotter i wouldnt worry too much.

It looks to me like its 8 years old your one, counting the layers, though i havent as yet dared cut one open myself!

Strategy wise I reckon similar to Fistulina, only slower still.

Andy had thought this to be Daedalea, and that based from binos from the ground.

All your points coincide with the points we've all discussed, but a non pos from the Jod has us holding back.

Andy took one of my slices to see if he could get anything from the pores, to look through his scopes.

Haven't heard back from him yet, will try & catch up with him soon.
