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,
What Mad Pursuit of the genetic code. There is a prologue outlining Crick's upbringing, education, and war work on magnetic and acoustic mines, and following World War II his decision on what branch of science to study, using the "gossip test". (Your interests are revealed by your gossip.) There is also an epilogue that outlines Crick's work after 1966, his move to the Salk Institute with his career transition to neuroscience concentrating on visual consciousness in primates, and some of his conclusions regarding research in theoretical biology, especially with regard to the brain sciences. Crick comments on various aspects of the DNA double
