Here is a lens with "spots" that are only visible against a lightsource. Otherwise the glass looks totally clear. Has anyone seen this before?

Looks more like haze than fungus to me.

yep, looks like haze.
"Haze" in this thread looks quite different: http://www.rangefinderforum.com/forums/showthread.php?t=79688&highlight=haze
Any other idea about the spots?

Could be the results of past condensation in a dirty lens, or even remains of the helicoid grease and ground down metal from the same. You'll know more once you get to it - which you can't avoid short of dumping the entire lens...

I had a lens like that, I always thought it was fine dust.
"Haze, condensation / helicoid grease, dust..." another opinion?

Not fungus and not separation. Looks like the left over stains from condensation.

This should be totally cleanable. That looks like a Minolta Rokkor 58mm. Remove rear mount, unscrew the rear cell. This sort of spots is almost always between the cells. You should be able to carefully clean it and make it look like new again.

Dust or haze. Easily cleanable but likely not effecting images anyway... not much.
