I wouldn't use too much moss on this species. I haven't grown it from flask, but it seems to do better if it is kept drier. So if you do use moss, you might want to remove it after a couple months. I killed one when I was watering at the same rate as other mounted orchids. In the winter I water it once every 4-6 days while I water other mounted orchids every other days.
It does well in the same environment as C. cernua.
Marni has culture tips here:
Schoenorchis scolopendria
If you are talking about wood of pine (not bark), it probably won't last for long. So Cork is probably better. I use Cedar shingles for most of my mount.
