Description:Species Description - Plants small, pale-green or whitish, densely tufted. Stems erect or slightly curved, simple or forked. Leaves erect-incurved or loosely flexuose to subsecund, channeled, narrowly oblong-lanceolate, gradually narrowed from the base, rounded-obtuse or acute, not or somewhat apiculate, the lamina very narrow (less than 6 cells wide), restricted to the leaf base; chlorocysts quadrangular in section, in surface view about 2:1 and arranged in a network; leucocysts rectangular in surface view, in 1 layer above and below the chlorocysts throughout the leaf. Gemmae commonly produced on brownish rhizoids at back of leaves (especially toward the apex), green, multicellular, ellipsoidal. Dioicous. Setae short (up to about 1.5 mm long); capsules immersed or barely exserted, smooth, hemispheric, becoming obconic and wide-mouthed when dry and empty; operculum very long-rostrate, straight; peristome none. Calyptrae very long-rostrate from a short, mitrate, coarsely ciliate-fringed base.
The immersed or barely exserted, wide-mouthed capsules lacking a peristome and the long, straight beak o n both operculum and calyptra are highly distinctive. The calyptra is shortly and coarsely cihate-fringed.
The genus has recently been revised by Allen (1992).
