The fungus seems to be prevalent in early generation Leitz lennses and it 
seems to have something to do with the natural resin that they used to use
to glue the elements together. You can learn all about it on Stephen Gandy's site. Go to the leica lens stuff. His site may be down
for a few days while he switches servers.
