    Revised def'n:
    A portion of plant tissue that is the outer layer (wall) of a fruit (PO:0009001), and develops from a plant ovary (PO:0009072) or a carpel (PO:0009030) wall.

    New comment: May be fleshy in fruits such as grape.

    Added new synonym to pericarp:

    fruit epidermis, exact synonym

    Two things. Epicarp is definitely not a synonym of of pericarp. It is the fruit epidermis, which is a part of the pericarp. The pericarp consists of three zones: exocarp, mesocarp, and endocarp.
    Epicarp is not commonly used, exocarp is the more common term.

    In response to the comment below, I think there is some confusion, as in the PO epicarp is listed as a synonym exocarp, not pericarp.

    Added fruit epidermis as synonym of exocarp.

    fruit epidermis as synonym of exocarp is not always true. It is only true when the exocarp is a single layer.
