Stipe (mycology) puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: When collecting mushrooms for identification it is critical to maintain all these characters intact by digging the mushroom out of the soil, rather than cutting it off mid-stipe. 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
Institute of Mathematical Problems of Biology Institute of Mathematical Problems of Biology The Institute of Mathematical Problems of Biology RAS () is a research institute specializing in computational biology and bioinformatics. The objective of the institute is elaboration of mathematical and computational methods for biological research, as well as implementation of these methods directly addressing the problems of computational biology. Since 2016, it has been renamed into the Institute of Mathematical Problems of Biology RAS – the Branch of Keldysh Institute of Applied Mathematics of Russian Academy of Sciences (IMPB RAS – Branch of KIAM RAS). The Institute publishes the scientific journal ""Mathematical biology & bioinformatics"".
