Thanks

Thanks Flaxton. Will have a closer look next time I'm nearby and get some more info to try to pin down the ID to a species

There are only two ways of being sure which species of Ganoderma it is. The first is to measure the spores and the second is to cut through the fruit body. If there is a sterile band between each years growth of tubes you have G applanatum if no sterile band G australe. See http://www.ispot.org.uk/node/104341?nav=users_observations

Thanks again

Flaxton, thanks again for this - I haven't been back to the site over the last few weeks but hoping to be there over the christmas period. Am I right to assume both are common enough that cutting will not be a problem? (I normally try to avoid this unless there are lots of fruit bodies)

Both quite common but if you cut through towards one edge of the fruit-body it will continue to grow but you will get the information you need.

That certainly looks like a

That certainly looks like a sterile layer above the tubes so I have agreed with G applanatum.

Thanks for all your help. I'm

Thanks for all your help. I'm reasonably confident my initial ID was correct (though definitely by luck rather than judgement). However, the sterile layer is nowhere near as clear cut in this fungus as in your photo of G.applanatum, so I won't be 100% sure until I've seen a few more examples of both species.

Or start to look at the spores which make life much easier;) at least for this species.
