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]
Presence of large spherical cells, 'sphaerocysts', in the stipe is an important characteristic feature to distinguish the members of Russulaceae from other mushrooms. In Russula, the stipe breaks like the flesh of an apple, while in most other families it only breaks into fibres. [13] The spore powder varies from white to cream, or even orange.
The fruit bodies of Favolus fungi are annual, and have a stipe that is situated laterally to substipitate or almost sessile. The shape of the cap is spatulate (with a broad, rounded end), reniform (kidney shaped) to dimidiate (divided into two equal parts). The texture of the cap surface can be smooth, or may have minute hairs, sometimes with ...
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
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]
An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. [1]
There is no clear demarcation between the cap and stipe. [13] The stipe can be up to 15 cm (6 in) tall and 6 cm (2 + 1 ⁄ 2 in) wide, though it tapers to a narrower base. It is solid in younger specimens, though is often hollowed out by insect larvae in older. [24] At higher elevations, two or three fruit bodies may arise from one stipe.
Morchella species have an ascocarp with a sponge-like pileus, with a hollow stipe and pileus. Verpa species have a cup-like or thimble-shaped, smooth or wrinkled pileus above a hollow stipe. Disciotis has a cup-like pileus with vein-like hymenial folds and a small or nonexistent stipe. [4] The ascospores are ellipsoid, smooth, and usually ...
