I have to confess to being confused on the mold and plume analysis myself. Mold that is blue is only mold. White stuff is a bit more tricky. Plume is supposed to be crystals that appear on the wrapper and are basically sugar. White pockets can be mineral growths and are hard and stalky and tend to be all round splotches but furry white stuff is at best not right. As the article below will state wipe off white stuff and hope it doesn't return. Even if its not mold it tastes odd.

I recommend this article. My two cents.
