Ganoderma resinaceum or Inonotus dryadeus

[David Humphries]

I was called out to look at this about a week ago...

Quercus ilex which has failed.....

Cool eh....needless to say the chickens are not too happy about it!<<<

 

Nor will the client be, when they see the bill for the wall repair.

 

Very good picture set there Bundle

Nice attention to detail.

Hi,

 

Thanks for everyone input as I have learnt some useful stuff. Ok to follow up the ID of this fungi I was well off with I.dryadeus but it does seem to be G.resinaceum. I have attached pictures of a cross section of the bracket. Also I have tried the flame test on the fruiting body but it was a little wet but did seem to melt.

 

Yesterday I have noticed a monkey puzzle tree that’s in decline with multiple young similar fruiting bodies (see attached pics) and looks very similar to the G.resinaceum when young?

 

Just a few other questions if anyone fancies replying but it looks like a few Ganoderma brackets are pretty similar in ID:

 

G.resinaceum, G.pfeifferi and G.lucidum

 

To clarify G.resinaceum is softer and lighter flesh than G.pfeifferi and generally G.resinaceum is not perennial but long lived (This one has gone through cycles that I have been aware of). Also G.lucidum has a lateral stalk. Is there any other good ID observation to separate these three?

 

Also there is mention of G.resinaceum causing more severe decay than other G.species. Anyone seen this?

 

To finish how rare is this fungus (if at all) if I have possibly seen two accounts this year?

 

Cheer steve

Bundle, where may I find tree root failure thresholds on paper?

Interesting thread, some good pics. Anyone gonna stick their head out and id the last fung?

Those numbers, indeed the the formula, are referenced to "Fraedrich & Smiley – Smiley & Coder 2001."

arh yes thats how this one started off....jumped the gun whilst inspecting and ID it as Inonotus dryadeus and told my boss....the tree has three main areas of fruiting bodies (here below the most developed side) on the buttress and the tree (Q.cerris) is a good size (balanced crown with good foliage) and right by a busy path used by the public....keen to leave the tree as long as possible any ideas apart from reduction?...chemical treatments etc if any??......(yes, ideally everyone needs to see the tree in the flesh to carry out tests to give a good indication of the decay development, hazard etc) just interested to see what people think from what they have seen so far...cheers

 

that the fruit bodies are within/between two regions of healthy and obviously compensating growth should be taken as a good thing, however resinaceum is invasive enough on robur, on cerris i would be avin me a probe about!
