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,
International Union of Biochemistry and Molecular Biology researchers. It is considered as a prestigious award for doctoral students. Candidates are selected based on a competitive project proposal and reference letters. The award scheme provides opportunity to work on a specified project in a different laboratory in a foreign country. It is associated with the journals "Biochemistry and Molecular Biology Education" (formerly "Biochemical Education"), "BioEssays", "BioFactors", "Biotechnology and Applied Biochemistry", "IUBMB Life", "Molecular Aspects of Medicine" and "Trends in Biochemical Sciences". International Union of Biochemistry and Molecular Biology The International Union of Biochemistry and Molecular Biology (IUBMB) is an international non-governmental organisation concerned with biochemistry and molecular biology.
