Discussion

The prominently prorulose laminal cells and well-differentiated cells of the leaf base distinguish Anacolia laevisphaera from A. menziesii. When sterile, Bartramia stricta may be mistaken for A. laevisphaera. The basal laminal cells of this species are subquadrate, to short-rectangular toward the margins, and 20 × 10–12 µm.
