Managing Trees with Decay & Dysfunction

[kevinjohnsonmbe]

Haven't seen anything but the picture yet David! Earliest I can get there is tomorrow so will know more then - got to be an odds on contender!

Not sure if this will work......

It didn't!

 

I tried to upload a go pro vid direct. Ive had to do it via youtube but as a consequence it's lost a lot of definition which is really disappointing, it was crystal clear before loading to youtube.

Blimey that was a stubborn old hanger.

 

What's your thoughts on decay culprits then?

 

Thought I saw melanine plaques on some of the upper surface layers which may indicate Armillaria. Some psuedoscloratial plating within the outer annual rings where you cleaned the with the saw (Kretz perhaps?) and not sure I would rule Polyporus squamosus out either !

 

No fruiting bodies knocking about the debris?

I was really disappointed that the resolution took such a hit David.

 

I've taken a couple of screen shots, first one was like a honeycomb effect - first thought was wasp / tree bee nest, not sure if this is a symptom of any particular decay fungus that causes this type of structure??

 

Second one, was the black bootlaces of doom but doesn't show up in sufficient detail in the video.

 

No fruiting bodies nearby to give any further clues.

 

I don't know what a melanine plaque actually looks like, since you mentioned it I googled it and was offered a vast array of camping plates!

 

Found this extract of an email exchange between some 'tree legends' on UKTC archive "...And Armillaria species shield off their vulnerable dead wood decomposing hyphae with melanine plaques and surround their hyphae inside rhizomorphs with a melanine layer, that protects the hyphae against attacks of toxins or acids (Quercus robur/petrea, Castanea sativa) produced by the living tissues of the tree.

 

RE: Ganoderma applanatum/australe on n.maple - implications

 

Do you have any pics of melanine plaque?

[David Humphries]

Is the honeycomb not just saproxylic beetle galleries in the white rotted wood?

These were taken from the inner surface of a hollowed out horse chestnut

Great example David. I once had a bank note sized piece of dried out L sulphureus 'mycelial felt' from a failed oak limb. Spent about a year in my chainsaw trouser pocket before crumbling!

Is that black crusty stuff on the right some plaque from Arm., or fb's of KD?

Melanine plaque of Armillaria

 

 

Certainly looks like a load of Kretz fruiting bodies though
