The relative humidity mold growth impacted some objects but not others. Objects impacted included music stands, a chair, and an instrument cover. Additionally, the ceiling around the supply diffusers was also black and assumed to be mold. 

The cause of the mold growth was the thermostat's fan was set in the "on" position rather than the "auto" position, which is incorrect for summer operation. The thermostat was changed upon discovery.
