The shape of terminal elements is their overall shape side-on, irrespective of any surface features [Pileipellis terminal elements (surface)]. Shape is best observed in a radial cross section of the pileus surface, but can also be observed in a scalp section (with care to interpret whether elements are being viewed end-on, or have fallen over and are side-on).

See also Pileocystidia, which are modified elements, differing from other terminal elements in shape and/or size.

Choose this state if: the terminal elements are more or less the same diameter throughout their length, or only slightly expanded towards the apex or in the mid-portion.
