Mold typically grows on organic materials that remain moist for more than 24 hours.
Molds require one or more organic nutrients. Because molds must absorb or transport their nutrients through the cell surface, they compete with bacteria for organic nutrients. Many molds have an advantage over the bacteria in this competition, because they can secrete digestive extra cellular enzymes such as cellulases. Thus they can degrade an otherwise insoluble organic substrate into its smaller soluble subunits, which they then absorb and use as sources of carbon and energy. This enables the molds to use carbon sources — including cellulose, lignin, and keratin (a common component of hair, nails, and feathers — that are unavailable to most other microorganisms.
Molds reproduce by spreading microscopic spores. Mold spores waft through the indoor and outdoor air continually. When mold spores land on damp organic material, such as wood, paper, feathers, hair, cellulose, petroleum products, rubber, carpet, etc., they may begin growing and digesting the material.
Some molds live in temperatures below freezing, and some like it as warm as 122° F. Molds primarily thrive and become a problem when the relative humidity level is above 60%, with temperatures between 50 and 90 degrees F. (10 to 32 degrees C.) and a pH from 3 to 8. Molds also tend to be more robust in poorly ventilated areas with little air movement to disrupt their growth.

Personally, I'm not worried.
