Any Idea What These White Dots On My Plants Are?

Question

These small white dots have been showing up on nearly all my plants, they only showed up recently and I’ve got no idea what they are or how to get rid of them.

The pictures don't show as clearly as I would like, but it looks to be perlite being exposed in the soil. Watering can remove a layer of peat, revealing some perlite. Feeling the texture, and inspecting closer will help you to get a better idea of what it is.

If it is not gritty, like the texture of perlite should be, then it could be a fungus. It would be very hard to identify a fungus from a single photo like this, though.
