Name that stuff on my lens!

Is it fungus, dust, or aliens?

Not fungus, since the marks appear to be on the surface of the lens. It's either something--a substance--that affected the coatings or perhaps just small traces of water. The latter can be resilient, but if you use some breath and microfiber cloth gently and repeatedly in the right spot, you may remove them. In any case, it's unlikely they will affect image quality.
