That material is known as "tree fern fiber", and is from the "trunks" of tropical tree ferns, as the name suggests. it is an excellent material for mounting plants upon, although I think you'll probably want to cover the phal's roots with a mat of sphagnum, or it will be entirely too dry.
Root rot in orchids occurs when there is insufficient air flow to the root system, and such a mounting technique will certainly remedy that, but let's hope you don't go too far in the other direction.
