I agree, it doesn't look good for the plant, especially since there are no new growths that could potentially save it.(unless there is one hiding behind the bulbs). Seeing the extreme wrinkling of the bulbs, I doubt there are any viable roots. I've lost two Oncidium type plants in the past, and once that orange infection sets it, that's pretty much the end of it. I'm sorry.
That's how orchid growing goes, you lose some in the beginning, and still lose some even when you have experience with them. After 4 years of growing I still kill some. I killed one last month, one of my favorites.
I agree with Carol, if you know what it was, you could always get another. I know it's not the same as having the original plant, but it's better than nothing.
