Mycology is the study of fungi, which are a group of organisms that includes mushrooms, molds, and yeasts. Fungi are found in almost all environments, and they play an important role in the environment by breaking down organic matter and recycling nutrients. Mycology is the scientific study of fungi, including their structure, physiology, ecology, and genetics. It also involves the study of how fungi interact with other organisms, such as plants and animals. Mycology has applications in medicine, agriculture, and biotechnology.
