Why has my Sigma 150-600mm sport lens got fungus on one of the inner lenses?

My lens is 4 years old but little used and well looked after, has anyone else had this problem?
Can you give more specific info on where it's stored? Have a picture of what you're seeing?

If the lens is stored inside a container, is there a dessicating agent in the container to minimize moisture? The more detail you can provide, the better. Hopefully we can figure out the best way to help.
