Demounting a Sigma EX DC 50-150 F2.8 I've found fungus!

Hi guys,

Much to my chagrin I found fungus behind the front element of my Sigma EX DC 50-150 F2.8 zoom this morning, I live on a boat which is usually fairly dry, but with winter etc.

Has anyone removed a front element on this lens? there are not the usual holes for remove the ring which holds the element in place.

Any advice would be greatly appreciated, thanks
