360 Symmar f/5.6 in Compound IV 10/2 Rear Element Removal

Look closely at the haze using a loupe, if possible. Fungus should show some dendritic growth patterns. Tan colored specks might suggest separation in the adhesive between the elements rather than fungus. If adhesive failure the only option might be to remove the glass elements and re-cement.

Re-cementing is not trivial but is possible by a careful worker. Look for a couple of posts here on various techniques especially jigging and heating while disassembling and re-assembling.

Well, after searching all the threads I could find on fungus, haze, etc. and reviewing Sandy's link, I've concluded my problem is definitely not fungus and is likely a mild case of separation. It seems benign enough that I plan to continue using the lens, just avoiding backlighted situations. I'm not willing to risk damaging the lens by attempting to re-cement it myself. If it gets worse with age, I MAY look into having it re-cemented professionally, but I suspect the cost of that option may be a strong deterrent. However, I AM grateful for all your help. It was much appreciated.
