Emerald

This gray-green moss is commonly found growing in large clumps In rainforests, In bogs, and In rainy mountain ranges.
It is modest-sized, growing up to 6 inches (15 cm) tall. It forms in small clumps, and is very rigid; it takes a lot of damage when trodden on.
When mature, emerald spiral capsules grow at the end of short, lime green sporophytes, eventually opening up during the early summer to release millions of spores; it does not cause any allergic reactions.
