This feature relates to the overall shape of the pileus as viewed side-on or in cross section. Ignore any modifications of the pileus centre (see Pileus centre shape).

This feature should be assessed using fruit-bodies that are fully mature and expanded but not too old. On young fruit-bodies the mature shape may not have developed properly; old fruit-bodies may become irregular or contorted.

Fruit-bodies may vary considerably in shape between specimens. Choose an average shape for this feature.

Choose this state if: the sides of the pileus are straight and more or less meet at a point at the apex.

If the pileus could be described as conico-convex (with the apex more rounded than in a strictly conical pileus), choose rounded.
