In mycology, a stipe (/ s t aɪ p /) 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. [1]
Stipe: The stipe is 3–7 cm (1 + 1 ⁄ 8 – 2 + 3 ⁄ 4 in) long and 0.5–1 cm thick. [5] It has either an equal structure, or becomes thinner near the base. It is light yellow, bruising rusty brown. The stipe has an evanescent veil which often leaves fragments on the upper part of the stipe [5] or the margin of young caps.
The cap surface is covered with dark grey to black erect scales. The stipe is up to 14 cm (5.5 in) long and 2 cm (0.8 in) thick. [4] It is coloured like the cap and has a woolly surface and a thick, ascending annulus. The pores on the underside of the cap are hexagonal, coloured dirty white or grey.
The stipe is 4–7 cm (1 + 5 ⁄ 8 – 2 + 3 ⁄ 4 in) high and 1–1.5 cm (3 ⁄ 8 – 5 ⁄ 8 in) thick and slightly swollen at the base, and is whitish with a whitish ring, which is initially attached to the cap. [16] Also known as a partial veil, this is a key identifying feature of the mushroom. [17]
Ascomycetes, sac fungi. A phylum of fungi characterized by the presence of an ascus, a sac-like structure where ascospores are produced. The largest group of fungi. Includes cup fungi or Discomycetes; most dermatophyte s; the mycobiont part of most lichens; powdery mildews; and fungi that produce truffle s. [37] ascospore
The stipe (stem) is smooth but fibrillose and streaky, yellow to orange-red, whitish towards base, lacking a ring. All parts become duller and grey with age, finally becoming entirely black. The spore print is white, the spores (under a microscope) smooth, inamyloid, ellipsoid, measuring about 8.5 to 11.5 by 5 to 7.5 μm. [6]
The parts of a kelp thallus include the holdfast (anchor), stipe (supports the blades) and the blades (for photosynthesis). [2] The thallus of a fungus is usually called a mycelium. The term thallus is also commonly used to refer to the vegetative body of a lichen. In seaweed, thallus is sometimes also called 'frond'.
Phellodon is a genus of tooth fungi in the family Bankeraceae. Species have small- to medium-sized fruitbodies with white spines on the underside from which spores are released. All Phellodon have a short stalk or stipe, and so the genus falls into the group known as stipitate hydnoid
