Any suggestions on genus?

[Bloomin_Aussie]

I picked this poor thing up at a nursery a few months ago. It was sitting there so sad, lonely and neglected I couldn't possily leave it there. Anyway, after I took it home I found it was growing (or should I say surviving) in a mix that was more garden soil than anything. Most of the roots were completely rotted and the rest were barely good enough to anchor the plant in the pot. Anyway repotted in a nice open mix with a couple of strands of sphagnum around the base and it's looking somewhat happier now. What I want to know now is... what the heck is it? To me it looks a bit like a Coelogyne but I wouldn't have expected to find one of those in a low budget nursery. Any other suggestions?

Oh I should add that this is in a 6" pot so it is a reasonable size. Biggest pseudobulbs probably about 3" long.
