Wild orchid from the Atlantic Rainforest

Today on a walk in the forest near home I found this broken branch on the ground, with this orchid on it. I would like to know which species is this, even if just the genus, then maybe I can narrow it down to the species. This was in the island of Ilhabela, off the coast of SE Brazil at about 150 meters high or so. Judging by the size of the branch it was on, I think it was located high up in the canopy, where there's more sunlight.





I placed it at a better spot where other people wouldn't see it, but I took home the small piece below which had broken out of the main plant and was separated. I willl try to grow it at home, but how do you suggest the potting? I'm thinking of tying it to a pretty wide and shallow ceramic pot with bark/sphagnum mix, leaving the 2 or 3 newer bulbs outside hanging, like the plant I found in nature, and wait for the roots to attach themselves.

 

It does look like some Maxillarias, but I find strange this growing in line. All Maxillarias I know grow in "clumps". And it wasn't very miniature (the plant anyways), the piece I got is about 30cm long.

 

I really don't know Kelly, maybe it is a Maxillaria. Guess I'll just have to wait it to flower to be sure. A bit of an off-topic question, do you think it would be a good idea to cut off the newer pseudobulbs to vase them? I'm afraid that if I leave these bulbs hanging (like they were in nature) the plant won't have force to really catch on and grow. Perhaps if I plant the newer ones on the substrate the plant will start to grow roots and then send out other hanging pseudobulbs on its own.
