Wild orchid in Northern Peru--ID help?

[vlhart]

Hi guys--

Back in December I went to Peru and saw tons of orchid species in the wild. But this micro orchid really caught my attention. It was completely covering many rock formations at Cumbe Mayo, near Cajamarca in a cloud forest area at about 8 or 9,000 ft and it appeared to have just finished flowering. I did manage to get one fuzzy picture of a small light yellow bloom.

I'm thinking maybe it is a pleurothallis but would love any input if anyone knows what it is! The leaves seemed very thick, almost succulent-like. Not sure that that shows up well in the photos.






Here it is growing up a rock face:
