Etymology: Ascomycetes is the plural of ascomycete, and the singular itself is a back-formation from the plural. The group's scientific name, Ascomycetes, was coined as a taxonomic name for the class of fungi, and only later did speakers treat it as an ordinary common noun, so that the singular "ascomycete" was derived from it. Its surface parts, "asco-" and "-mycete," look like a combination of Greek elements: "askos," meaning "bag" or "wineskin," and "mykes," meaning "fungus." The name fits the group well, because these fungi produce their spores inside tiny sac-like structures called asci.
