What is "stipe"

Stipe \Stipe\, n. [L. stipes a stock, post, branch: cf. F. stipe.] (Bot.)

1. The stalk or petiole of a frond, as of a fern.

2. The stalk of a pistil.

3. The trunk of a tree.

4. The stem of a fungus or mushroom.

"stalk of a plant," 1785, from French stipe, from Latin stipes "log, post, tree trunk" (see stiff (adj.)).

n. 1 The stem of a mushroom, kelp, etc. 2 The trunk of a tree. 3 The caudicle within the pollinarium of an orchid flower 4 The petiole of the frond of a fern or palm

n. supporting stalk or stemlike structure especially of a pistil or fern frond or supporting a mushroom cap

In botany, a '''stipe ''' is a stalk that supports some other structure. The precise meaning is different depending on which taxonomic group is being described.

In the case of ferns, the stipe is only the petiole from the rootstock to the beginning of the leaf tissue, or lamina. The continuation of the structure within the lamina is then termed a rachis.

In flowering plants, the term is often used in reference to a stalk that sometimes supports a flower's ovary. In orchids, the stipe or caudicle is the stalk-like support of the pollinia. It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak). A stipe is also a structure found in a number of organisms that are studied by botanists but that are no longer classified as plants. It may be the stem-like part of the thallus of a mushroom or a seaweed, and is particularly common among brown algae such as kelp. The stipe of a kelp often contains a central region of cells that, like the phloem of vascular plants, serves to transport nutrients within the alga.

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, 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:

1. the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.)
2. whether it has remains of a partial veil (such as an annulus or cortina) or universal veil ( volva)
3. whether the stipes of many mushrooms fuse at their base
4. its general size and shape
5. whether the stipe extends underground in a root-like structure (a rhizome)

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.
