Imagine they are both Ganoderma species The first more than likely to be G. resinaceum and the second possibly being either G. lipsiense (applanatum) or G. australe (adspersum) .

Hello Sean, happy new year to you. Relatively little fiscal resource actually spent on this particular operation, as my team is funded from a different budget from Burnhams. (We see our time spent there as developing training) So really only the materials and Nods time. Value for money in terms of the natural resource that is being maintained. Have you noticed many instances of bracing in New Zealand since you've been over there? .

Not sure about Sweden, but here in the UK it is a fairly rare species on our Oaks. I have no direct experience of it with regards to decay failure. Ryvarden and Gilbertson state in part 2 of their volume on European polypores that it developes a white rot of the heart wood in mature oaks. Heinz Butin briefly describes in his tree diseases & disorders book that it is a slow growing parasite more commonly associated with older oaks. Also stating that it can develop a white rot of the upper trunk. Karlheinze Webber and Claus Mattheck say in 'Manual of Wood Decays' that the White rot can lead to brittle fracture of the stem. That's about the all the reference to P. robustus/Fomitiporia robusta I have at hand. Hope you find it of use. .

Hello, I would imagine that they are P. robustus/Fomitiporia robusta .

Its noted as being a random genetic abnormality of the growing tip of a plant, associated with many genus of trees through to cacti But can be caused by the bacterium Rhodococcus fascians Here on prunus .

Brown rot of Laetiporus sulphureus decay on oak White mycelium can be seen between the rays and annual rings. .

Kretzschmaria failure on lime .

Your welcome. Not as yet, but funnily enough I was on the phone to Barchams yesterday looking at getting in a Wild service to replace a mature Ash we recently took out .

One of our North London victorian parks which has about 600 trees in it. .

Been posted in tree health care before, but now reposting to place similar vids of our inspections together on one thread. photos on the thread below, from post 59 http://arbtalk.co.uk/forum/tree-health-care/51461-aerial-inspection-6.html .

Clarification In the video I have stated that the bracing used is a particular brand, it is actually a system that has recently been developed by treeworker. For further information please contact Nod at..... Tree Climbing Equipment Online Shop - Treeworker.co.uk - Treeworker home .

Thanks to all those who bidded for the subscription. The highest bid as of midnight last night was of £85 from A Pettersen-Firewood&Chip Many thanks for your generous donation to the Childrens Trust .

Right host, but I don't think so Paul. clusters of P. ignarius (the Willow bracket) are more commonly seen like this with a thicker rim and dark top surface. Phellinus ignarius - Willow bracket - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists .

I don't really like to guess, having been caught out a llittle too often in the past with 'gut feelings' Would really need to see further shots including a more panned context image and a focussed close up of the pores .

if you're interested in a comparison between the two, the directory above may offer some advise Daedaleopsis confragosa - Blushing bracket - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists Daedalea quercina - Maze gill - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists I don't think the fungi in your shot is Daedaleopsis confragosa btw regards David Nice shots of the blushing bracket Jules .

That's the spirit Jake Pm me with what you'd like to offer for it. Good luck .

Bump Come on peoples, I hear there is a particularly good article on tree fungi in the upcoming issue .

Who knows, it is a natural phenomenom but a rarity I imagine. Not many Lichenologists around as I understand it (bit like Mycologists really) particularly ones who can get up on a trunk or in to a canopy, but an interesting case study for sure. .

Pleurotus species I would of thought possibly P. ostreatus .

Although pollarding happens naturally in storms etc, Man has created the vast majority of these old beech pollards in the UK. The problem is that this practice has all but ceased (small amount still going on in Sweden, Spain and a few other places) and the pollards are now so far lapsed that it is difficult to bring them back into a viable cycle. This means that the ones we have left are becoming a scarce & dwindling biomass of habitat for the organisms that live on & within them. Worth conserving I believe .

Its called Pyrenula nitida http://jncc.defra.gov.uk/_speciespages/2554.pdf http://www.dendrology.org/site/images/web4events/pdf/Tree%20info%20IDS_06_pp65_p67_Burnham.pdf .

Fair question, I'm not a lichenologist unfortunately but imagine its the age of the host (this one being around half a millenium) that is critical for the conditions required for this particular lichen. The surrounding trees are young in comparison and do not provide the same growing environment .......yet .
