Emerald

This green moss is commonly found blanketing giant areas In moorlands, In rainy mountain ranges, and In heathlands.
It is modest-sized, growing up to 3 inches (8 cm) tall. It forms in extensive patches and they overwhelm an area rapidly, and is extremely light; it struggles more than most during dry spells.
When mature, emerald oval-shaped capsules grow at the end of elongated, lime green sporophytes, eventually opening up during the mid-autumn to release dozens of spores.
