Bryum clavatum is a small cushion-forming moss, with the bright-green new growth contrasting with the dark, often silt-impregnated older and lower stem regions. The nerve length is variable and may fail before the leaf tip or extend to form a stout point. The capsules are distinctive: often very long (2.5-5 mm), curved, dark purple when mature and borne on short stalks (setae) only about 1 cm long.
Widespread in New Zealand on wet soil banks or dripping rock faces.
