That looks like fungus and is generally not trivial to clean.  Be careful, as it may spread to other lenses nearby...

 

A good way to avoid it is to keep lenses in a dry area and/or near moisture absorption packets.

Fungus- as stated above. Use an Ammonia based lens cleaner to get off, but the damage to the lens coating is going to remain.

 

I place lenses with fungus under a UV lamp to kill any remaining spores. I bought a camera collection from the wife of a collector that passed away, they had been stored in a Damp Safe. Safe- BAD. I ended up disassembling a lot of lenses and cameras, used the UV lamp. 1 Year later- fungus has not returned. It was active, got to most of it before eating into the coatings and glass.
