Torn down gypsum ceiling above the shower in a house built in 69. What is the white color? Is it the gypsum that has rubbed off on the wood or something else, like house mold?
 
  • Ceiling removed above shower in 1969 house, showing wooden beams, insulation, and white residue. Question about whether white is gypsum or mold.
  • Exposed ceiling above shower with white marks on wooden beams, possibly from gypsum or mold. Surrounding tiles and ventilation vent visible.
Looks like black mold. Has the vent just exited into the wall?

Yes, I agree it's black mold, but I'm curious about the white color. It's a ceiling, and yes, the vent is very close to the tiled wall.
 
Sorry, read the headline. Looked at the pictures, forgot the headline and saw the black
🙈.

But it could also be white mold, less likely it's gypsum since it has paper on the outside.
