Looks like dust. Mold has sprawling linesgrowing out from a nucleus.

Mold looks, moldy.

Here's some examples of lens mould/fungus:

If it is mould it's best to keep the lens separate from any others you own so that it won't infect them.
I keep my mouldy lens in open air on a shelf so that it gets plenty of airflow to hopefully prevent it growing back.


You can remove light mould with isopropyl alcohol, you just need to be careful that you don't scratch the lens in the process. (it's also not 100%, some mould comes off easily, if it's been there a while it may etch into the glass and be permanent)
