Fungus one week after repotting, why?

I would definitely remove the blackened roots. Also make sure you are getting good air flow to the roots if you have them in plastic pots put holes on the sides and bottom. Don't put them in decorative pots until they have become healthy again.

Also, I do not prefer sphagnum moss for phaleanopsis type orchids (some folks do). I like a mix that contains the compacted chunks of moss.
