Eric,

When we were in the Holy Cross neighborhood after Katrina I did an
assessment of a house which was about to be gutted. Fortunately we saved
that one, but it did have a peculiar condition on the bedroom walls. They
appeared to be lime based plaster like the rest of the house (and most of
the unremuddled properties there) but they were exhibiting mold growth at
the waterline. My trusty pocket knife revealed that a gypsum veneer
(probably Lowes drywall compound) had been applied to the plaster surface
and the mold was in the veneer. As you suggest, the paper is usually what
usually supports the mold, put it appears there must be an additive in the
compound that did too.

Rudy

Actually the mold grows on the sheetrock paper facing (food source), not the
gypsum
