Copper Moss

This copper moss is commonly found blanketing giant areas In marshes.
It is short, growing up to 3 inches (8 cm) tall. It forms in thin clumps and they are slow to spread and grow, and is very flexible; it can easily endure being trodden on.
When mature, emerald triangular 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 allergic reactions.
