All of these responses are very good advice! Julie, thanks for mentioning cinnamon as I have forgotten that it is a well-known natural fungicide!
Maxi- to try to answer some of your earlier questions, rotted roots are black, thin, soft, and often watery. Yes, I think that one root you were referring to has some rot on it; so you can treat it with cinnamon or the fungicide of your choice. Yes I think those are 2 new growths at the crown base- but they'd better just be roots and not a flower spike! (believe me- some orchids get really desperate to flower!!)
The best thing I think your phal has going for it now are the healthy roots. Bark is my #1 choice for phal medium, and you're already doing that as well. I wouldn't be too concerned about the wrinkled leaves at this time; again, because of all your healthy roots. Again I agree with Julie about staking the plant until it gets its roots established.
Lastly, you mentioned you've had the phal in the same potting medium for several years, but it has been in bark for (give or take) only a year. Your phal didn't become sick overnight, and it won't fully recover that fast, either. Also, if it has been a year and it hasn't died under your care, congratulations! Orchid growing: you're doing it right!
Just keep doing what you're doing, ask if you need help, and be patient as your phal recovers.
Good luck!!
