Sometimes mold is on things as small as splatters on walls in Waco.
We like to use the example mold won't grow on your car fender, but if you spread butter all over your car fender, it will grow on the butter which is on your car fender.
Sometimes this is even true of mold which is growing on something on another material which will also grow mold.
The photo is of a wall in a commercial building, in the Central Texas Marketplace area of Waco, TX, which appeared to have mold on the wall.
Technically, that is correct, but actually the mold was on what appeared to be splatter drops from a drop food or drink. The mold was easily wiped off by SERVPRO of Waco with antimicrobial, though the spots from the food discolored the wall.
The employees were relieved.
