Schistidium antarctici

Schistidium antarctici is a species of moss found in Antarctica and subantarctic islands. It can be found in compact clumps or as continuous beds of moss. It is quite variable in color from brown to dark green. It grows on both soil and rocks, but reproduces more often when growing on rocks. In the Windmill Islands area of Wilkes Land, Schistidium antarctici is the most common bryophyte. If its habitat supplies ample moisture, it may form a "carpet-like" growth, but if its habitat is dry, it forms a short "cushion-like" growth....read more on Wikipedia.
