Ascomycota

Ascomycota are fungi which produce spores in microscopic sacs called asci (the word is Greek for a bag or wineskin). An individual fungus belonging to this division is called an ascomycete. An ascomycete produces great numbers of asci at any one time, all contained in a structure called an ascocarp. Each ascus contains eight ascospores. A major exception to this structure are the yeasts, which are secondarily unicellular.

Examples of ascomycetes: morel, yeast.\n
