White on staghorn fern soil

Hi everyone,
I have a seemingly healthy staghorn fern, but I just checked the soil and saw all this weird white stuff. Can anyone tell me what it is and what I should do? Thanks so much!
13ft to light, indirect
6” pot with drainage

Technically it’s saprophytic fungi which isn’t one of the harmful ones. But it does point out the substrate is staying too damp and has a lot of organic content, which inevitably leads to the harmful fungi and root rot if you don’t let the substrate dry out/increase airflow around and in the substrate..

If you don’t like how it looks you can remove it with a spoon and work on correcting the dampness issue with letting it dry out, or moving it to a free draining substrate like bark/compost/little bit of moss, it’s epiphytic type fern so it doesn’t want it’s roots in very dense stuff that stays really damp.
