Ascus Definitions:
A specialized cell, characteristic of the ascomycetes, in which two haploid nuclei fuse to produce a zygote, which often immediately divides by meiosis; at maturity, an ascus contains ascospores.

Ascus Notes:
Asci are the sexual spore-bearing cells, which are made in ascomycete fungi. Usually eight ascospores are contained in asci, these spores are produced in the process of meiosis, and later they undergo the mitotic cell division. Nonetheless, asci of some species or belonging to some genera appear in numbers of 1, 2, 4 or multiples of 4.
