An ascus (from Ancient Greek ἀσκός (askós) 'skin bag, wineskin'; pl.: asci) [1] is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division.
Ascus (Ancient Greek: Ἄσκος) was a giant from ancient Greek mythology, who in conjunction with Lycurgus of Thrace chained the god Dionysus and threw him into a river. The god Hermes (or, according to other tellings, Zeus ) rescued Dionysus, conquered (ἐδαμασεν) the giant, flayed him, and made a bag (ἄσκος) of his skin.

The eight ascospores are produced inside an ascus. Sordaria squashes can give us information about crossing over during meiosis. If no crossing over occurs a 4:4 pattern is produced: four black spores, and four tan spores all lined up. If crossing over does occur there is a 2:2:2:2 pattern visible, or a 2:4:2 pattern.
