For example:
* Ascomycota - a division of fungi that produce spores in a sac-like structure called an ascus.
* Basidiomycota - a division of fungi that produce spores on a club-shaped structure called a basidium.
* Zygomycota - a division of fungi that reproduce sexually by forming a zygospore.
So, whenever you see "-mycota" in a word, it means that the word refers to a group of fungi.
