Emerald

This slate or green moss is commonly found blanketing giant areas In moorlands, In heathlands, and In bogs.
It is modest-sized, growing up to 5 inches (13 cm) tall. It forms in extensive patches and they spread and grow quickly, and is overwhelmingly tough.
When mature, emerald V-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the early autumn to release dozens of spores.
