Copper

This copper moss is commonly found growing in small clumps In moorlands, and In heathlands.
It is average-sized, growing up to 6 inches (15 cm) tall. It forms in small clumps and they overwhelm an area rapidly, and is extremely robust; it can easily endure being trodden on.
When mature, emerald crescent-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the early autumn to release millions of spores; it does not cause any allergic reactions.
