In botany, the female reproductive structure of fungi that develops into the fruiting body.
From Greek 'archi-' meaning 'primitive' or 'chief' and 'karpos' meaning 'fruit,' referring to the primary fruit-producing organ in fungal reproduction.
Fungi have such alien biology that mycologists invented special terminology—'archicarp' is used to describe the very first stage where a fungal structure commits to becoming a mushroom, which is totally different from how plants make fruits.
