unidentified fungi on Castanea tree

[kiltoncomp]

after having said , in another thread, i never find any fungi on chestnut trees,
heres one i found yesterday on a live Horse Chestnut tree,
although there are several similar species in my books, none resemble this one in its colour,
quite a large group on one of the lower branches of the tree,

With the greatest respect kiltoncomp Castanea (sativa) is the Sweet Chestnut from the Fagaceae family.
Horse Chestnut is in the Hippocastanaceae family and species name is Aesculus hippocastanum
Your image shows the bark of Horse Chestnut which you've ID'd and they are suckers for fungal loading. Sweet Chestnut are very resistant to fungal attack and have very durable timber.

I was looking at a huge cut stump of Ah yesterday and the cut surface is covered with fungus which you will be able to tell me what it is!

thanks for the correction, at least i got the common name right
as you've probably guessed, trees are not my strong point! this is one of those situations where a little research pays dividends

Don't worry Brian, fungi aren't my strong point so between us we should get things right!

Hi Brian,

If I might be allowed to throw my novice hat at this, the fungus appears to have a pnikish colour to the underside, and a hairy/felty upper surface.

Looking through my books, (and based purely on that as reference) the best I can come up with is possibly a Phlebia sp. maybe Phlebia tremellosa.

I'm sure I will get shot down in flames, for that suggestion, as it will probably be something completely different - but as they say, nothing ventured...

Regards
Mike.

Hallo,

to me it looks like Trametes hirsuta.
I'm quite certain it is a Trametes (s.l.) and the old and green fruitbody remnants there exactly look like those old Trametes versicolor, hirsuta and so on which have half been destroyed by the weather and half been eaten by insects .

bestr egards,
Andreas

DOH - I'll get my coat. (Well at least I've learned something by being wrong again ).

Hello Andreas, all the references to Trametes hirsuta i can find , say that it is found on dead hardwood/deciduous trees only, given that other fungi have been turning up where they are not supposed to be, the fact that this was on a living Horse Chesnut might not be so unusual ?? ,
there is a fallen branch of the same tree that has what could be the same fungi on it , but they are to far gone to get a good description from, all i can say is that they resemble the more usual Trametes shape, and not like the ones on the tree.

Hallo,

absolutely correct, and I only said "looks like". I'm quite certain that it is a Trametes (or close related genus as Antrodia e.g.).
Trametes hirsuta is coming very soon on dead trees and is one of the first in the succession. So may be it can already grow on dead parts of the bark on still standing trees. But you are right, I also have never observed that.

Another suggestion would be Trametes zonata/multicolor, which would be even more alike than T. hirsuta. But also the ecology "standing tree" is not quite usual for this one.

best regards,
Andreas

Hello Andreas,
My comments were not intended as a criticism of your observations, after all your knowledge and experience far outweighs mine,
It was just that I thought it was unusual for it to be on a “live” tree, as it is normally noted only on dead wood,
As the branch was above head height I could not get a pic of the top surface, but from what I could see, it did not seem to be at all hairy, as T. hirsute usually is.

It could be that that particular branch is already dying, and the fungi has got a head start??
A return visit is in order to see how this one develops I think,
And thanks for your comments so far,

Brian.
