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 of the Cell was later retitled "Biologie Cellulaire" (; 1977–1980), becoming "Biology of the Cell" in 1981. Articles were originally published in either English or French, with summaries in both languages. Content from 1988 is available online in PDF format, with papers from 2005 also being available in HTML, and from 2006 in an enhanced full-text format. The journal's 2014 impact factor was 3.506. "Biology of the Cell" is indexed by BIOBASE, BIOSIS, CAB International, Cambridge Scientific Abstracts, Chemical Abstracts Service, Current Contents/Life Sciences, EMBASE/Excerpta Medica, MEDLINE/Index Medicus, and ProQuest Information and Learning Articles are primarily research and reviews.
