I agree it looks like a hybrid involving fuliginosum and a very beautiful one at that. Australian Orchid Nursery is producing some amazing crosses along these lines right now, though sadly few of their plants have yet percolated over to the US. Please let me know if you ever have divisions of this one to sell or trade.
That is absolutely gorgeous! I love how the Aussie natives come in such wonderful shapes, sizes and patterns! I would say it is a X with a speckled specie (obviously).
If you cannot ID it anytime soon, try an orchid club
