Ah-ha! I think fishmom may be onto something. It shouldn't be too difficult to trace one of those wild leafy growths back downward to its source to determine if it's something coming out from below the surface of the media. I will be totally flabbergasted if you tell us it is actually originating from the body of the Phalaenopsis somehow. Maybe you can gather up the supplies you need for a repot and solve the mystery.
