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,
Network of Concerned Anthropologists Network of Concerned Anthropologists The Network of Concerned Anthropologists (NCA) is an independent ad hoc network of anthropologists seeking to promote an ethical anthropology. The network is concerned that the "war on terror" threatens to militarize anthropology in a way that undermines the integrity of the discipline. Therefore, the network offers the possibility to sign a pledge where it is stated what kinds of work anthropologists should not engage in. The founding members of the Network of Concerned Anthropologists include Catherine Besteman, Andrew Bickford, Greg Feldman, Gustaaf Houtman, Roberto Gonzalez, Hugh Gusterson, Jean Jackson, Kanhong Lin, Catherine Lutz, David Price,
