C. cuspidata (Pointed spear-moss) is a relatively common weft-forming moss of roadsides or grasslands.

Depending on the conditions, plants can range from being olive-green to bronze coloured. The stems are irregularly pinnate. The side branches and the main shoots are typically pointed like spears, thereby the common appellation for the moss.

The leaves roughly triangular in shape and are slightly U-shaped in cross-section. The double nerve is faint and practically invisible under a handlens. Under a microscope, the inflated hyaline alar cells are characteristic.

This species can be mistaken for Wijkia extenuata in it's general habit but the latter species has a very obvious hairpoint. It can also be mistaken for Acrocladium chlamydophyllum but this species has more concave leaves which tend to be less wide spreading from the stem and is also more sparsely branched. 

The species was previously under the family Calliergonaceae.
