I may as well ask these questions perhaps for the benefit of everyone:
In my questions I'm assuming the ordinary amount of fungus... which is
typically spiderwebby and affects one or two lens elements.
1. How significant a problem is fungus? ie. wil it affect any and all
lenses with time?
2. How much does it really affect picture quality?
3. When cleaned how commonly does it reoccur? Sometimes, always, never,
depends on how you treat them?
4. Apart from the link on Siddiq's page on fungus.. is there any other
links or references to the fungus problem?
I'd personally like to know so anyone can feel free to email me off list if
they wish to or share the answer here.

it off. It had been stored away in a dry closet for several years and
when I was cleaning the 50mm, f1.8 I noticed a couple of black specks on
the rear of the front element. The largest is about the size of a couple
of grains of pepper and the other is considerably smaller. Might this be
the infamous fungus that I'm reading so much about?
I'm not so sure -- fungus usually appears more greyish or white, and often
shows up as "blooms" or "spiderwebs"; sometimes, from a distance, your
optics can just look hazy, like a softening filter is being used. There's
almost never a definite "edge" to the fungal bloom or web, either.
