Description
Species Description - Plants about 0.5-1.5 cm (rarely as much as 7 cm) high, Stems black, flexuose, sometimes bearing dark-red, globose brood bodies in leaf axils or on radicles and protonemata, regularly producing minute, reddish club hairs in axils of upper leaves. Upper leaves 4-5 mm long, long-setaceous, sometimes denticulate near the apex. Synoicous (or sometimes dioicous). Setae 10-45 mm long, red-yellow or orange-brown; capsules 1.7-2.5 mm long, brown or yellow-brown, horizontal to pendulous; cilia of endostome in 3s (occasionally in 4s). Spores 9-13 µm, smooth or very finely papillose.

The narrow, almost setaceous leaves are anomalous in the Bryaceae, but the pear-shaped capsules and the nature ofthe peristome leave no question of relationship. Leptobryum wilsonii (Mitt.) Broth, of South America has gametophytes scarcely distinguishable from those of many Pohlia species.
