Any idea what this is? Vandofinetia roots...

I noticed a little fungus growing in the sides of the sphag n bag, so I decided it was time to end that before it took over or affected the plant itself, so I put it in a tiny clay pot with a mix of primeagra and the epiweb chunks. Anyway, when I was inspecting the roots, I noticed these whitish plaques on the undersides of the roots. To me they look like potentially normal, albeit hairy, roots vs some kind of fungal badness.

What's the verdict? Any intervention required? I tried gently scraping them away and they seem pretty adherent.
