Emerald

This gray-green moss is commonly found growing in medium-sized clumps In rainy mountain ranges, and In bogs.
It is big, growing up to 9 inches (23 cm) tall. It forms in large clumps, and is overwhelmingly durable.
When mature, emerald oblong capsules grow at the end of elongated, lime green sporophytes, eventually opening up during the mid-autumn to release thousands of spores; it does not cause many allergic reactions.
