Thanks chaps .......the often raised question of how to tell the difference between Ganoderma applanatum and australe has been a perennial puzzle for both Arborists and field mycologists. Although the colonising strategies are quite different (see Schwartze below) the morphological features are fairly similar. I thought that I'd bagged the subtle identification differences that various authors (Lonsdale, Butin, Ryvarden, Mattheck et al) had written about such as crust thickness, flesh/tube colour, evidence of trauma layers, mycelium in the tubes, but microscopy has proved a couple of times that what I thought was applanatum, was in fact australe. http://arbtalk.co.uk/forum/attachments/fungi-pictures/116928d1362903479-ganoderma-enspec-20research-20paper-20-20ganoderma-20on-20trees.pdf To try and get to the bottom of the issue of identification we collabourated with the field mycologist Andy Overall, who leads the London Fungous Group, to offer up field samples which he then checked under the scopes to assess spore size. He wrote up his findings in the British Mycologigal Society Field Mycology journal which has been posted on AT before but worth sharing again. http://www.londonfungusgroup.org.uk/wp-content/uploads/2016/09/Ganoderma.pdf [ATTACH]218363[/ATTACH] .

Ganoderma - applanatum, australe, carnosum, lucidum, pfeifferi and resinaceum. A varied group which can be found across a wide host range, mostly broadleaf but also noted from coniferous species Species list - British Fungi G. applanatum on birch and showing the galls of the yellow flat-footed fly (Agathomyia wankowiczii G. australe on beech G. carnosum on yew G. lucidum on hornbeam G. pfeifferi on beech G. resinaceum on oak .

On Mothering Sunday as well, now that's beyond the call of duty ! shared our team thoughts/experiences via the survey. regards David .

Cherry with Grifola from earlier in this thread. Fruiting has occurred regularly on both sides of the buttress root that has the obvious girdler. had the chance to run the airspade over the target area today to have a closer look and to sound the roots with a nylon hammer. We found that there were a significant number of Armillaria rhizomorphs all through the rooting zone, we suspect these (due to their size and vascular condition of the tree) to be of a more benign species of Armillaria, possibly A. gallica On further inspection we found that the majority of the roots around the Grifola fruiting sites are in good sound vascular working order. We'll continue to monitor the trees condition

Who knows, perhaps some mischievous imp has raked them all out there in the middle of night In a radial ring or just random? .

My understanding is that it is of the saprophytic persuasion, mostly associated with decayed needles (Keizer 2007) .

Ta da ! See them quite often at Capel Manor on the Cedars by the maze on the back lawn .

Any Cedars near by? Cedar Cup - Geopora sumneriana | NatureSpot .

Indeed ! .

Had to call a fiend with this one as I couldn't key it out with any of my books Lentinula edodes - Shiitake Not native to the UK, so the holes in the oak substrate (which I originally had thought were insect holes) probably had inoculated dowl plugs. Possibly dumped on to the Heath by someone who didn't get a 'crop ' back in their garden. .

Yes Jake, there was a small remnant of a long desiccated chicken bracket that I didn't take an image of whilst I was there today, plus I've seen it fruit on this tree before. it's rife through the red oaks here at work. .

Inonotus hispidus on a roadside Sorbus .

The axe wounds on the targeted trees from earlier posts from this thread haven't bared fruit in terms of buds, but this axe wounded ring barked beech has........go figure !?! .

Tick tock, tick tock........ Squirrel damaged beech from post one on this thread. Image one 2008 Image two 2012 Image three 2017 .

Red oak that took one hell of a beating in some storm or other and has/had Laetiporus munching its way through the heart, has now put on a fine triple stemmed reiterating canopy and is feeding off its self. .

Can you expand on that please Kenty? .

Couple of kilometres from the epicentre of an 8 million strong city Mick, no wild horses or deer here (the odd muntjac perhaps) .

Just returned home to find a beautifully hand carved cherry spoon had been delivered, which was kindly donated by jrose. Joe's girlfriend Anna is a very talented carver, I certainly recommend people having a look at her website. Anna's Beautiful Hand Carved Spoons I suspect the spoon will be used and admired over many years. Thanks to you both. Big thanks also to Mr Bullman, who having to jump through a number of hurdles this year, managed to facilitate the charity raffle yet again. .

Not dog wee, i sniffed it fairly widespread on one site, across about 200 acres. Damage must be occuring at sunrise or sunset or perhaps both. It will be intersting to see if the slime flux affects the bark tissue and vascular volumes directly under the flux run. I'll be adopting a watching brief and will report back if I witness any dysfunction and successional colonisation. .

No idea at this point, but we're gathering intelligence to try and work out who, where, how & why. The issue is now starting to manifest into tree health issues, slime flux showing as direct effect of the cause. .

Think ya kinda missing the point of the thread here Gary, you not seeing the teeth marks :biggrin .

Some one just doesn't like my trees .

No15 on the map is a new host species today, (roadside dysfunctional Acer cappadocicum) which is now the 8th separate tree species that F. fomentarius is hosted on across the site. Acer cappadocicum Betula pendula Fagus sylvatica Poplus x canadensis Quercus cerris Quercus petraea Quercus robur Quercus rubra .

Inspecting a Cappadocian maple today and literally stood on top of a nice wee group of Sarcoscypha sp, either S. coccinea - scarlet elf cup, or possibly S. austriaca, which apparantly is the more common of the two species. .

Turkey oak that fell due mostly to Ganoderma resinaceum, but with trunk that has long colonisation of Fomes fomentarius. These two similar aged brackets are on separated wood volumes and are at slightly different stages of maturity. The lower one is currently sporulating. .
