ethnomycology
The study of fungi, both harmful and beneficial, in relation to human affairs.

It is said that this is the study of the historical uses and sociological impact of fungi (also known as, "fungi lore"), and can be considered a subfield of ethnobotany or ethnobiology.

Although in theory the term includes fungi used for such purposes; such as, material that is easily combustible and can be used for lighting a fire, medicine, and food, including yeast; it is often used within the context of the study of psychoactive mushrooms.
