As I understand it (and I will admit to a lack of expertise), this is
a fungal growth, and it actually eats the wax substance that composes the
recording, thus making the damaged cylinder at best noisy and at worst
unplayable. Extreme manifestations of this can be seen on wax cylinders sold
at flea markets and similar sources whose original owners stored them in
warm, damp places, encouraging fungal growth. The fungus can be removed, but
the wax it has eaten cannot be restored (that I am aware of, anyway) so
that mold-damaged cylinders are basically unsalvageable.
It is still being debated whether shellac, also being an organic substance,
can be affected by a similar phenomenon.
