Rigid Beard-moss - Didymodon rigidulus

Alternative names
Barbula rigidula

This is the commonest Didymodon species on calcareous stone. Its shoots form dark green tufts, 0.5 to 1 cm tall. The narrow leaves are about 1.5 to 3 mm long, taper gradually to the tip, and have more prominent nerves than other Didymodon species. Oval-oblong capsules occasionally develop between autumn and spring. These have short peristome teeth that are not or only slightly twisted.
