Identifying moldy fruit in the refrigerator

Moldy black raspberry

Keeping fruit fresh in a refrigerator is a challenge.  These black raspberries became moldy after less than a week in a refrigerator.  Most of the mold on the surface was mycelia without reproductive structures.  I used a clear 3M transparent tease tape and with a 85% lactic acid mixed with fuchsin dye to identify the organism under 400x power.
