Basidia are found in basidiomycetes, a group of fungi that includes mushrooms, toadstools, puffballs, and shelf fungi.
Here's how it works:
* Basidia are specialized cells located on the underside of the mushroom cap (or on other fruiting bodies).
* Meiosis (cell division) occurs within the basidium, producing four haploid spores called basidiospores.
* The basidiospores are then released into the air, where they can germinate and grow into new fungi.
So, the club-shaped structure is a key part of the reproductive cycle of basidiomycetes.
