Lamellulae are short lamellae which do not extend fully from the edge of the pileus to the stipe (or point of attachment, if a stipe is lacking). They are often located between the main lamellae in regular series of different lengths. One series might extend half-way from the pileus margin towards the stipe, another a quarter of the way, and so on.

Choose this state if: there are no lamellulae, and all lamellae extend from the edge of the pileus to the stipe or point of attachment. This is not a common state for agarics, occurring in Russula and a few other genera.
