The Phal abuse ends here.

Can anyone tell me what this is on my phal's roots? Fiance caught me eyeballing an orchid when we were out the other day and surprised me this evening. =) The plant looks very healthy, leaves roots and all. But there is some white fuzz on the bark and I am not sure if underneath the bark is fine bark or some kind of potting mix, I can't tell. The roots have some kind of scaling look on them and it's fuzzy. I am not sure if this is just because the plant is probably a clone hybrid or if it's because the roots are dry or if it's something else? I have attached pictures. It looks like many of the roots up top closer to the surface as well as the bark have white fuzz. The fuzz on the roots is kind of a mix of green and white. o_O What is this?
