Copper Moss

This copper moss is commonly found growing in large clumps In marshes.
It is average-sized, growing up to 5 inches (13 cm) tall. It forms in extensive patches, and is slightly light; it burns easily in strong sunlight.
When mature, emerald teardrop-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the mid-summer to release millions of spores; it can cause allergic reactions.
