Barbula unguiculata is a yellow-green moss that forms cushions up to 5 mm high. The leaves are spreading and 1-2 mm in length with recurved margins and protruding tips (excurrent as a sharp spike). The leaves are strongly curled when dry. Its much shorter setae (6-10 mm) distinguish it from B. calycina.
Widespread in New Zealand on exposed rock, walls and dry earth.
