Jackie how do you find these things?! Just showing how much we have to learn about the fungi in our environment. With Polypores: firstly; scratch the surface of the pores to see if there is any colour change. Secondly; it can be useful if you are able to safely cut a section through the fungus. This will let you know a). the colour of the flesh inside. b). the length and colour of the tubes, they are most probably going to be a different colour to the pores and may be a different colour to the context (internal flesh). You may also be able to tell if it's had more than one years growth - you will see layers. Thirdly; see if you can see any spore deposits below the fungus to work out spore colour. If you're very lucky you might be able to temporarily stick something over part of the pore surface and obtain a spore deposit!! Fourthly; try and determine what type of rot it is causing - white, brown or pocket. It looks woody or is this just a skin growing over another old fungus? I've developed a sheet for when I'm collecting or looking at polypores with a whole list of diagnostic features. If you like I can send you a copy. A lot of the time there is no name available for Aust. spp, however sometime you can be surprised. A useful book is "The Polypores of Papua New Guinea" (Opera Botanica Belgica 11) E. Quanten. I think you can download it from the internet.

Now how did I know you were going to send me back there for another look? Yep, woody; it looked pretty hard, so I might be cutting into it with an axe! Yeah, I did look for spore deposits underneath but didn't see anything. I'll see if I can stick something under it. A copy of your diagnostic features thing would be good. Electronic or paper? I'll message you with my direct contact details.

OK everyone I'll send it through tomorrow.

I've added some more photos, and hacked the thing off the tree to try for spores. It's been sitting around reeking of mushrooms for 24 hours but no spore action so far. Looks like there are multiple growth layers in it. It has some heft to it, as the bit I removed which was all but the lower part of the white bit, weighed 400 grams. There was no discolouration after cutting. The 5th photo is of the second, older fruiting body on another tree, which is completely dead and partly burnt. It is very yard and woody.

Jackie You've done some great information gathering on this Polypore. I'm still working on it - though spores are a stumbling block and unfortunately some of these things have hyaline (colourless) spores. I'm working on ones I collected at the weekend with this type of spores - great, it drives me nuts! I put a glass slide under part of mine, though sometimes if you have used paper and you tilt it to the side so light shines on it obliquely you will see a textured area. The thing is you can list it as say species 1 or whatever, record all the information you have, which is really valuable. Then sometime in the future you, or someone may find one that corresponds to this one or if you're fortunate extra data may come in that enables a positive identification. some measurements would be useful ie how long are the tubes? The dimennsions of the bracket. If I come up with something I'll let you know.

Hi Pam, The bracket I brought home is 13cm across the point of attachment, and the old one would be closer to 20cm I think. The active white bit has tubes 8mm long, but some of the older layers of tubes are up to 20mm long I think, although it's hard to be positive what constitutes a single layer in the older material. I used pink paper in case the spores were white, but so far nothing. I've shoved a bit of glass under there as well now.

Thanks for that Jackie.

Likely to be Ganoderma applantum/australe (Southern Bracket Fungus/Artists Conk). Rub the lower surface, it will bruise to a red/brown/rusty colour if it is. Have one here on a plum tree, looks exactly the same. http://www.elfram.com/fungi/fungipics_h.html#ganaust_a

Hi Norm, Looks similar to the two images from Victoria, not so much to the two from Narooma RF walk. I scratched the lower surface with a knife while it was still on the tree and got no colour change. I had the thing in the house trying to get a spore print for a few days and it gradually darkened from white to tan, but never shed any spores as far as I could tell, and eventually got mouldy and started smelling, so that was that. If i ever see one again I'll try sticking an object under it in situ instead for spores to collect on.

Am happy to send images of the similar fungi that is here if you want but am not sure how to do that. The upper bracket seems to have died ( I often see that on wattles here), and it is now regrowing again under that. This one stains instantly when bruised. If it is the one I mentioned above they dust a large area under them with brown coloured spores when that happens..

That one definitely sounds like a Ganoderma

Hi Jackie, have just uploaded images of the fungi that is similar to yours growing on a plum tree here. The first 3 images are of it, note the staining, from gently rubbing, it is 100mm across the top. The third image is what I mostly see, the good folk at Fungimap have agreed that it is australe and the last image shows the base of a wattle (Hickory Wattle - falciformis, I think) with dead brackets, some still attached others have fallen off and others still living. Hope this helps and not confuse.
