White fuzzy fungus on phal stem base

[jeesunkist]

So I sought for help a few weeks ago about a phal with no roots (which this board wouldn't let me insert the link for some reason) and thanks to everyone's advice and help, it has been repotted into new media since and still keeping up with its green.
However, I have noticed a white fuzzy fungal growth around its base stem area today and was just a bit concerned. It doesn't seem like snow mold but wanted to make sure it was nothing else harmful. Anyone have any idea what this is? What should I do?
