Stipe (mycology) Stipe (mycology) In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi,
Biology: The Unity and Diversity of Life Biology: The Unity and Diversity of Life Biology: The Unity and Diversity of Life is a college-level introductory biology textbook that helps students learn how to apply critical thinking and scientific methods to developing their understanding of basic concepts in molecular biology and biochemistry, genetics, biotechnology, reproduction and embryonic development, anatomy and physiology of plants and animals, evolution, taxonomy, and ecology. The book is designed to create in students a broad foundation of knowledge in biology and is frequently used in AP Biology classes in American high schools. Each book includes an interactive CD-ROM with links to additional instructional material.
