A sticky situation over a Ganoderma.

[Harrison2604]

haha this just complicates matters cos i think its a Ganoderma resinaceum,

 

Haha. Well, when hamadryad said that it was a G. pfeifferi, I thought he was referring to your picture as well as mine.

[Tony Croft aka hamadryad]

sorry, i meant the picture of the bracket at the top, not the fine specimin you presented

 

oh dear! O.k lets start over, first image in this thread is G. resinaceum, 100%

 

second posted image is G. Pfiefferi 100%

does you also specialise in such decay techniques and mycology because those are the fields i am very interested in and any advise for entering those fields would be useful.

 

I would suggest concentrating on your tree knowledge to begin with, then when youve got that soted start getting into fungi and decay, a good understanding of wood anatomy is a good starting point on this road as there will be many terms youll need to get familiar with.

 

We have to remember fungi are micro organisms, their fruit bodies may well be massive at times but their life is 99.99% of the time played out on a microscopic level.

 

and prepair to be addicted once you start, its a fascinating world when you get down to this micro level, and discover that life is not driven by the big things but by the tiniest.

I would also say get familiar with a microscope of 1000X oil immersion capacity as this will make identifications far far easier.

Oh blimey haha.

 

I know my image was G.pfiefferi... I got it off the fungi directory!!

 

I was posting it because I thought it was the same Ganoderma spp!

 

Wrong... again!

 

I'll get there one day.

I’m currently a student studying arboriculture and was wondering if I could ask you guys to answer a question for my research into Ganoderma fungal brackets and how they affect the tree.

Below is a Ganoderma resinaceum that I found, on a mature oak tree in a back garden. The tree is showing slight signs of dieback in the upper canopy but overall looks healthy with good size and shape providing high amenity for the surrounding houses. No other brackets are on this tree and the soil around the tree is in good condition and well watered with little competition for light or nutrients. There is space around the tree for an easy felling job (no green houses or ponds to destroy) with good access via road for removal. If the tree fell it could damage a house if fell in the wrong direction but the owners want the opinion of an arborist over the matter.

What would your response be to seeing this Ganoderma on the tree and the detail provided?

1. Fell

2. Canopy reduction of the tree to remove deadwood or

3. Test the tree for rot using resistograph or other such equipment

4. Leave the tree but continue to inspect for further signs of dieback or other symptoms over the next few years

5. Take other action (please provide details)

 

Cheers lads

IMO it all depends to targets at risk. If the tree can safely be reduced to a safe height which reduces risk to property or the public then that could be your way forward. Picus and resistographs are good but do cost money and most private clients sorry all the private clients i have suggested this too have either said just reduce it or fell it. Very rarely will i leave a tree if its in decline with signs of decay fungi in a back garden unless the risk is identified as low. ie garden backs onto a wood, 80% chance if it fails it will fall that way and the clients rarely use the garden. Finally if its good i can fell it and turn the stem into wildlife habitat.

I've just read through the whole thread again and made myself like a complete tool. I was on the complete other end of the stick

haha bad times, still, we got there, anyway, what would your reponce be to seeing the G resinaceum on the tree harrison? it would be very useful for my research. cheers mate.

Honestly mate, through my experienced on Arbtalk, It's probably completely pointless asking me. I've given advice before and hamadryad corrects me not long after, which he will probably do shortly after this post, guarantee but whenever I see a Ganoderma on a tree that isn't looking so healthy, I weep and recommend removal or pollard, depending on where it's located and where it would fail.

 

I don't have access to any decay detecting pieces of kit, so I'm unable to test for the percentage of sound wood or xylem functionality and such like!
