A stipe is the stalk or stem of a mushroom, connecting the cap to the ground. It provides structural support and helps transport nutrients and water from the soil to the cap. Stipes can vary in thickness, length, and texture, depending on the species of mushroom. In addition to mushrooms, the term "stipe" is also used in botany to describe the stalk of certain plants, such as ferns. In this context, it refers to the part that supports the fronds or leaves. Understanding stipes is important for identifying and studying various types of fungi and plants.
