Copper

This copper moss is commonly found blanketing giant areas In heathlands, On rotten logs, and In bogs.
It is enormous, growing up to 1.3 feet (38 cm) tall. It forms in thin clumps and they are exceptionally hardy, and is slightly resistant.
When mature, emerald kidney-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the late autumn to release millions of spores; it can cause severe allergic reactions.
