Discussion
The tiny but often fruiting Tortula lanceola is uncommon in the flora area. The bulging, rounded cells of the adaxial costal pad have the distinctive appearance of cows’ udders, and viewed laterally have the appearance of longitudinal ridges. H. A. Crum and L. E. Anderson (1981) pointed out that the antheridia are borne naked in axillary clusters, but occasionally bracts, albeit rudimentary, are present. Tortula acaulon has much the same gametophyte, but the sporophyte is reduced and cleistocarpic. Tortula atrovirens and Crossidium aberrans have a somewhat similar leaf section but the former lacks an awn, and the latter has a short awn, and the adaxial costal pad is of low 1–2-celled filaments.
