Good luck and watch diligently. You problably can't spend too much time on the hunt for it. I would just take early anything near the mold as it seems it has a way of spreading, though this runs it's own risk because the mold seems to do better near open wounds aka: giant branches removed. I spent 3-4 times as long harvesting my MOB in trying to remove all of the mold carefully and with clean tools, and in clean workspaces. This ended up using two outdoor work stations before it even got near the trim table.
