Bird's-claw Beard-moss

Barbula unguiculata

Barbula unguiculata, also called as Bird's-claw Beard-moss is a species of moss belonging to the family Pottiaceae. Its color is usually distinctive, a kind of bright yellow-green shared by few similar acrocarps such as Trichostomum species. Its leaves always look opaque, thanks to its densely papillose leaf cells. In dry conditions, the leaves frequently twist or curl around the stem, whereas they spread outward when moist. Each leaf is parallel-sided for most of its lengths.
