Algae growing on my Elizabeth Ann Buckleberry roots?

[Cymbaline]

I noticed some odd growth on my Elizabeth Ann Buckleberry's roots and I'm wondering if anyone knows what it could be and whether it's a bad thing?

Could it be algae?

I ask because back when I first bought it, it showed some black fungus and I took extreme measures to get rid of it . Described HERE ).

To rehabilitate the poor thing I was soaking it daily in fresh water and every few days in very diluted solutions of KelpMax and fertilizer. It's living in a makeshift green house of sorts and it was ( still is ) always moist.

It's still living in my makeshift greenhouse and I mist it almost daily but only soak it about 1x a week but it still stays pretty moist in the enclosure I have.



So I'm just wondering if anyone knows what it maybe and whether it's harmful? I'm sure if it's a type of algae it maybe because it's very moist and humid and maybe I can start to cut back on the humidity since it seems to be doing okay.
