A somewhat diminutive moss, male and female reproductive parts occur on the same plant. The 6-10 leaves, arranged in 3-5 pairs are 1.5-2.5 cm long and 0.3-0.4 mm wide. Leaves are similar in appearance whether wet or dry and partly folded to the base (another distinctive characteristic of this genus). These folded portions average one-half to two-thirds the length of the leaf. The leaf mid-rib ends 6–15 cells below the apex (most other moss species have longer mid-ribs). The spore capsules are at the end of a 2-3 mm stalk which is yellow when young, becoming reddish with age. Capsules are ovoid to oblong-ovoid and inclined to slightly bent.
