Fusarium solani?

[Skycat]

I just got this Phal yesterday for $1 (because Lowe's is doing this thing where they basically put the clearance plants on clearance) and I was repotting it today and found this on a rotted root



Ugh, the rest of the plant looks pretty healthy for having been grown in moss!





If the plant looked sick, I'd just toss it and not even bother with this nasty crap. Anything that's orange on a plant and not supposed to be there really freaks me out.

I've cut off the really bad root (and several more rotten roots), and I think I saw a little bit of orange stuff on another root, but I can't find it now, and I think I'm just going to leave the plant where it is for the rest of the night because there's TONS of mosquitoes and I'm not going to have any blood left if I spend any more time out there.
