what lens and how much?
if, indeed fungus, $100 would be about as much as I would pay.
Anymore and you will end up with a great looking paper weight.

p.3 #2What's this on my lens?
The lens that I showed is an old one -- probably from the 1980's. I can't for the life of me take it apart to get to the insides, but when I took it to a local repair shop they said that it's probably the lens coating sticking on to some fibers.
Makes sense too, since it was in storage for the past 20 years or so in a case with a cloth with it as well. Ironically, the side that was facing the cloth has almost all the "fibers", while the other side does not.

So, the fibers inchwormed off the towel into the lens and then took a nappy poo under the front element?

Haven't you heard of capillary effect?

BTW, does anyone know of a good source of fresh silica gel desiccant sachets in N. America ?
You can get large quantities of silica gel desiccant powder at many craft stores, where it's sold for drying flowers. It's cheap as dirt, but you have to make your own sachets.

Colwell that is AWESOME. Is there a smaller (much smaller...) version of that?
Yes. There are two smaller dry cabinets from the same supplier, http://www.xdry.com/camera-lens-optics-storage.asp
The product I have is CS-151SS, which is a combination of CS-51SS (top two shelves) and CS-101SS (bottom three shelves). You can see on the right side of the photo that there are separate doors for the top and bottom sections. I think I have three 'spare' shelves left over, after I set it up for my gear.

I think some people have fungus in their lenses and don't even realize it.

Haha, I don't think it applies to all materials!

Well, after a lot of reading it appears that there is no evidence that this can spread from lens to lens, so I will be keeping the lens. I live in a place of low humidity and not much heat, so chances are the fungus will not spread. I will take it to a local camera shop for confirmation of the Internet Diagnosis as well as to see if they will clean it.
For those curious, this is a first issue Sigma 70-200 2.8. As I have mentioned, the photos coming from it are absolutely stellar.
I was always under the impression that fungus does spread from lens to lens, and to keep the said lens isolated from the other equipment. I had an OM Zuiko 24mm f/2 I got and there was a spec in the optics that I thought was fungus. Here is the link
I took the lens to a shop and after looking at it for like 20 minutes in a clean room and whatnot, he said it is not fungus. So I would take it to a place and see what they think before returning it or whatnot.
