Radial grooves extend from the center of the cap to the margins.

The mushrooms have caps with distinct radial grooves, particularly at the margin.

They are pleated with radial grooves extending from the center to the edge of the cap.

The surface has radial grooves that extend nearly to the center, and feels greasy but not sticky.

The cap shows radial grooves that outline the position of the gills underneath.

The western inner wall does display a fine radial groove texture, but is otherwise nearly featureless.

In old specimens, the hyphae around the peristome sometimes stick together to develop radial grooves.

The surface of a millstone has usually a series of radial grooves in which the powdered material collects.

Radial grooves define sac-like compartments within the bag.

The cap surface is smooth but dotted with fine, easily detached scales, and often develops shallow, radial grooves near the margin.

The cap has radial grooves extending to nearly the center, and sometimes develops cracks in the margin, which has small rounded teeth.

Mature caps appear somewhat translucent, and develop radial grooves mirroring the position of the gills underneath.

They are yellow to brown in color, covered with radial grooves when moist, and fade to a lighter color as they mature.

When moist, radial grooves (striations) can be seen on the cap that correspond to the positions of the gills underneath.

Dorsal osteoderms, which are found on the backs of aetosaurs, are often ornamented with radial grooves.

The cap surface is smooth, and marked by a variable number of raised radial grooves extending from the center of the cap to the margin.

Here it travels with a deep artery of the arm (the profunda brachii), which sits in the radial groove of the humerus.

The sticky cap surface is smooth and shiny, and does not retain any fragments of the partial veil; the cap margin has fine radial grooves.

The cap margin is either straight and slightly curved inward, rarely slightly wavy, and sometimes has radial grooves in moist specimens.

The cap surface ranges from dry to moist, smooth to covered with fine whitish hairs, and is mostly even with translucent radial grooves at the margin.

Mid-shaft fractures may damage the radial nerve, which traverses the lateral aspect of the humerus closely associated with the radial groove.

There are fine radial grooves near the cap margin; young specimens, the margin is curved inward, but it straightens as it ages, and eventually develops cracks.

The somatomotor portion of radial nerve innervating anconeus bifurcates from the main branch in the radial groove of the humerus.

The smooth cap is hygrophanous (i.e., it changes color as it loses or absorbs moisture), and has shallow radial grooves extending about halfway up the cap.

With the lateral and medial heads of the triceps innervated, the radial nerve emerges from the radial groove on the lateral aspect of the humerus.
