This feature relates to the overall shape of cheilocystidia, in side view, irrespective of the shape of the apex (Cheilocystidia apex shape) and any branching (Cheilocystidia branched). The different shape states are simply based on where the widest point is, and the length/width ratio.

If the shape is described with modifiers such as 'narrowly' clavate or 'broadly' clavate, choose the state being modified (in this example, clavate). However, if the shape is described as 'slightly' clavate or 'subclavate', chose the state that otherwise matches (which will usually be cylindrical).

More than one shape can be present.

Choose this state if: the widest point is near the base. Other terms for this state are ampulliform, flask-shaped, conical and utriform.
