Hi Treemover, sorry, I only just tuned in too your update post. Would be really interesting to see a photograph of the actual cross section, to compare with my records. With CS and that level of internal advancement I would expect to see a greater level of external dysfunction. Any news on the tree's future status. Regards Cassian...

Hi Jules, Your description relating to the trees above has parallels to Gums with advanced CS symptoms, with large panels of thickened bark likewise coming of in sheets though not until the final stages of decline/death. Any chance of supplying some pictures? This disease is very new to S.E. Qld gums. The only arborists here that I am aware of who are familiar with CS have been involved with the Energex VTA Program. We did not see this prior to 2009.

Hi Treemover, the pics you supplied are classic VTA symptoms of what we would call early to mid range symptoms of canker syndrome. When I say we I make reference to a relatively small team or arborists two at management level working for the S.E. Qld Utility company Energex (we were contracted to) and one who was my assistant working on the Energex VTA Program (Jonathan Cowan brother to UK Andrew Cowan), a project which ran from 2007 until June 2012 (currently suspended due to Qld Gov cutbacks). In the case of advanced symptoms once the trees are at the point of failure DBH’s are generally up around 1.5 to 2.5m, though we have seen scores of young trees (DBH .5 to 1m) with early CS symptoms. The embrittled wood is expected to be soft rot induced and looks very much like a brown rot type decay in the hardwood, where as decay in the sapwood looks like a white rot (I understand this is normal for simultaneous soft rot wood decays in Europe). We have very limited data on wood decay fungi in Australia, with very limited data shared between Australian arborists. I will be very interested to hear news on the clients analyisis.

Note - Tree Mover -The pics above are indicative of early symptoms, our experience in Oz is that with drought the disease is considerably slowed (3 year timeframe to ringbarked and standing dead with high rainfall). If this is new to Britain then with the climate there I would expect rapid spread and gum decline/death. Check pages 8-9 of the report for symptoms ranging from early to advanced. I just remembered the old post was named Sudden Gum Death... Regards Cassian.

Gday Gents, as a Qld consulting arborist I have been gathering the data on this significant disease for Energex a S.E. Qld Utility company for 4 years. The first tree that I found was 2009 on Mt Glorious, since then the disease has spread to 50 locations in S. E. Qld (hundreds of trees), 35 locations recorded on Google Earth. It’s a scary one has it is spreading and killing so fast. The symptoms in your globulus are identical to symptoms affecting E. saligna, pilularis, and grandis and are similar to those effecting Corymbia intermedia and Lophostemon confertus in S.E. Qld. The data I have gathered has gone into 3 ETS/Energex reports (of mine) the most recent I had published as a two part article in the Australian Arbor Age (Oct-Nov 12 & Dec-Jan 13). Gums are going from having early symptoms (infection into bark) to advanced within a 3 year time frame and are being ring barked and killed, as part of the advanced process wood is embrittled resulting in shear failure within 2m of ground level (Out of 9 tree failures 2 where still live at point of failure and where 90% ringbarked). The disease is unknown by the Arb profession and forest pathologists in S.E Qld, though since my alerting DAFF pathologists (QLD) I have received recognition that the disease/disorder is present. I have named the beastie Canker Syndrome as it appears that a number of organisms may be involved (as opposed to a single causal agent). The key causal factors for spread are high rainfall, with gums in disturbed sites where soil compaction is prevalent. I ran a presentation on the syndrome for The Qld Arboricultural Association earlier this year. To see a copy of the original report check our website – Education | NaturaCulture. The Canker Syndrome update report (29/8/12) is second from the end in the list of past reports/articles. I made comparison to the canker disease Chrysoporthe cubensis in the update report. I would greatly appreciate feedback on the report from the British profession as I am getting nothing from Australia. I discussed this in an earlier Arb Talk thread under the name Popcorn Canker. Bad news if its in the UK too. Regards Cassian (expat Brit Merrist Wood Arb).

To whoever is interested, I commend Guy's (TreeSeer)and my efforts to generate a movement that will hopefully create a collective human action to manage and hopefully suppress a fungal organism/s gone rouge. As with all rouge pathogens the issue lies with an (altered) environment that favours the minority -the pathogen over the majority -the antagonists (from the pathogens perspective) or the beneficials (from a trees). Like you Fungus I see harmony in the tree world as a result of working with the soil food web. For the few of us in a position to take action in relation to this SE Qld epidemic we will achieve success by harmonious interaction. I encourage you to take a leaf out of your own book and be like a mycorrhizae - supportive. Cassian

As far as conclusions can be reached in this phase of the analyses and with the present macroscopical documentation, I would attribute the dramatic effects to a combined strategy of the Cryptonectria and K. deusta, where the Cryphonectria is the primary parasitic and not wood degrading pathogen and K. deusta is the secondary pathogen starting off as a saprotrophic soft rotting the heart wood inside out and becoming parasitic once the living tissue is reached through invasion of radial rays and the remaining living cambium is killed, after which it fruits with anamorphs within a year developing into teleomorphs. If this is the case, the FB's of Cryphonectria should be found scattered over the trunk (causing local bark and cambium necrosis and/or canker ?) and the FB's of K. deusta should be found at the base of the trees. This perspective really fits our story and the perspectives given me by other Oz Arbs involved (Sean Freeman). There is another fungi (3rd) in this equation. In all the failed dead Eucalypts I have observed (and photographed) another fruiting body (small thin and brown - below) has been present. Have also seen it on standing dead and live gums with the advanced canker symptoms and prolific wood decay. The presence of this FB is I believe an indicator the tree is close to failing. This 3rd FB is indicative of stage 3 and snap time.

Hey Fungus - I really appreciate your input - best regards Cassian.

Below are a series of photos giving perspective of what a psuedo mycologist would call FB's. The Grey/white and Black FB are the same with a 12 month time gap. We are seeing what we think at present is Cryphonectria cubensis & Kretzschmaria deusta. Gents if I could show you the outbreaks I am witnessing and the spread tree to tree and on individuals I am sure you would agree this disease is as bad as they get. The Orange FB on the next post is another common form we are finding.

Hi gents, based on Genuses/species affected Sudden Gum Death is a better name. The attached are examples of what I have been calling White rot. Whichever it is this is a consistant across all infected trees. The bark becomes infected first then pockets of wood, in some cases Gums are killed (E. grandis & E. saligna) without signs of canker & with outer growth increments colonised by the white rot.
