Second opinion on my wilting phal!

[Apricot]

Hello all!

About a week ago I have noticed that my first phal's leaves have wilted to the wrinkled state that they are in now. I have stopped watering her and have increased the humidity of the room (with a humidifier) to help it along. Right now it's just hanging out in a plastic container with a wet sponge (roots are not touching the sponge). The leaves have not gotten better and I'm not sure what else I can change to make sure she survives and eventually flourish. This evening I went to inspect the root system and noticed that the majority of the roots and one of the bloom spikes (blooms have been falling off one at a time) are all connected to this very dry looking base (picture attached). I want the plant to be healthy and I'm not sure if its alright to leave this dried off section attached to the orchid. Any suggestion will help. I just want her to look as healthy as she did when I got her.

Advanced thanks for all the help.
