Much of ancient mythology was based on sex and fertility worship, and here is the hermaphroditic symbol of sexual unification in the mushroom itself. The underside of the mushroom takes on the appearance of a vulva penetrated from below and supported by the male phallic. It has formed into a embodiment of interfused duality. The stem of the mushroom (representing the male phallic and the sun, as in an obelisk) is joined with the cap of the mushroom (the underside of the cap represents the female uterus and earth and the top of the cap is symbolized as a single female breast and also the sun). Once the cap of the growing mushroom begins to separate from the stalk, it is no longer considered exclusively male. In the biblical stories, Adam existed before Eve. Metaphorically, Adam represents the phallic stages of the mushroom, which occur before the female stages of the growth cycle. Eve (the eave of the mushroomnm and symbolically, the female portion of the mushroom), is born from the side of Adam. In nature, when the Amanita's cap separates to form the cave (canopy), it figuratively pulls a rib out of the stalk.
