What is the white powdery substance that sometimes appears on the cigar wrapper?

If you see white powdery spots on your cigar that looks like mold, chances are it's only bloom, which results when the oils in the wrapper cause the leaf to mature. If this is the case, simply wipe the bloom off gently with your finger. It's perfectly harmless and a sign that the leaf is of good, healthy quality, but if you want to prevent it, keep your temperature and humidity down.
