Mycology
Study of fungi
Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. Fungi can be a source of tinder, food, and traditional medicine, as well as entheogens, poison, and infection. Yeasts are among the most heavily utilized members of the fungus kingdom, particularly in food manufacturing.
