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,
Dietary biology of the golden eagle in the French Pyrenees, the Italian Alps and Bulgaria. There is no information on how golden eagles capture insects or what kind of insects they hunt, although slower, larger, terrestrial insects like large beetles seems likely. One of the most fascinating, though relatively little studied, aspects of the golden eagle's biology is how it interacts with other predators in a natural environment, especially other large predatory birds. The golden eagle is a powerful hunter with few avian rivals in size or strength, although what it gains in these areas it loses somewhat in its agility and speed. Golden eagles are
