I had similar problems when I allowed growth to become to dense. I don't know that it's mold but, I wasn't going to smoke it. Pics don't really show the "undead" quality. Even leaves brown and dead from age seemed more alive than the "zombie" buds...
Mold was restricted to a single area so I put that aside from the rest of the haul. Rather than cut offending areas, I cut off the entire bud the mold was in as well as the buds to either side. Left shot is the suspected area haul. Right pic the throwaway from same.
Throwing it out cost me 10%-15% of total yield but, I didn't start growing to smoke the worst of the yuckiest.
Sorry for your loss
