Emerald

This lime green moss is commonly found growing in large clumps In marshes, and In heathlands.
It is modest-sized, growing up to 6 inches (15 cm) tall. It forms in small clumps and they overwhelm an area rapidly, and is very strong.
When mature, emerald kidney-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the early autumn to release millions of spores; it does not cause any allergic reactions.
