Is this photo upside down then? If that is a vent pipe does it get cold in the winter and warm where the photo has been made? Then it would be condensing where the mold is. The black lines further on the beams seem like that it has become wet and dry periodically. The wood seem still hard? You can test it with pushing a screw driver in.
