What is this white growth in my terrarium?

For Christmas I got a terrarium that came with moss, clovers, and a few tree seeds. My terrarium has been growing for about two weeks and the clovers have sprouted but something white is growing too. I'm not sure if this is mold or the moss trying to grow. Any insight would be very much appreciated. I've attached a photo that may be able to help anyone identify what it is.

It is probably fungus. Make sure your terrarium is not too wet.

Unsure which you are directly referring to, the white cotton-like stuff on the right and bottom right against the glass looks like "dampening off" which will kill seeds and sprouts, you can gently remove or stir the mold to hinder its growth and open the lid to let moisture out, adding a fan for a LIGHT breeze will prevent its further growth, it is caused by soil too damp and no air flow, a light breeze will also help the plants not to grow tall and skinny and just bend over from not being able to support itself.
