Re: green mold spots on tobacco leaves
If there is slight mold on a tobacco leaf, just mist it with 50:50 diluted, distilled vinegar. Allow it to dry, until the acetic acid smell dissipates. The actual hazard of moldy tobacco is the aflatoxin from Aspergillus sp., and only if you use it as chew or other oral tobacco (or as a cigar wrapper). Aflatoxin is destroyed by the heat of burning tobacco, and no toxin is detectable in either the direct or sidestream smoke.
For me, the main problem is the yuck factor. If I can smell mold (any variety of mold) on the leaf, it pretty much spoils a cigar. If I can't smell it (and I don't use chew or snus), I don't worry about it.

EDIT: I should also point out that the stem of a tobacco leaf is more hygroscopic (water attracting) than the lamina. As a result, mold is most often seen on the stem first. It may then spread to the lamina, though it usually doesn't. If mold is just on the stem...well, I don't smoke the stems.
It smells like mold on anything else. Smelling it is as dangerous as laying out two slices of bread, and beginning to make a sandwich, but discovering mold on the bread. Don't stick your head in the bag of tobacco, but just notice the smell as you open the bag. It's really distinctive.What does mold on tobacco smell like?
