Bartramia nothostricta is a species of mosses in the family Bertramiaceae and is endemic to the south-east of Australia.

It grows in small colonies in moist places, and is recognised by its leaves which look like a shaving brush and by its bright green, spherical, lollipop-like capsules.

Bartramia nothostricta moss plants are 5–10 mm (0.2–0.4 in) tall and form dense clusters or "turfs" which are bright green above and brownish below.

[1][2] Bartramia nothostricta was first formally described in 1987 by David Catcheside and the description was published in Memoirs of the New York Botanic Garden.
