Help! I have an Oncidium that has something wierd going on. I noticed some new growth that turned brown and was basically rotting. When I pulled on it, I noticed lots of tiny white/tan balls (shaped like eggs) underneath. Looking at the media, I'm seeing the same things, only dark brown. I've never seen anything like this in my orchids and can't figure out what they are. (I also found the same thing on one of my Phals.)
