The absence of prominent cluster bracts over the flower spike rules out X. australis, the upper aspect of the leaf appears flattened to concave in some, this is also inconsistent with X. australis, therefore this is likely either X. resinosa or the affiliated X. concava.
That 'hoof' shape and the colour of pores indicates a Phellinus sp. maybe P. robustus. This genus causes white rot and is found on both dead or living wood of both angiosperms and gymnosperms . Ganoderma have white pores and also cause 'white rot' and grow mainly on angiosperms. Good images, thank you.
Looks like D. sulphurea going by the brown markings. If you have good eyes or a hand lens look at the labellum. If it has one ridge its D. sulphurea, Two ridges down the centre back especially, then its D. aurea. Also its a bit south for D. aurea.
