Emerald

This gray-green moss is commonly found blanketing giant areas In bogs, and In rainy mountain ranges.
It is short, growing up to 1 inch (3 cm) tall. It forms in thick clumps, and is very light.
When mature, emerald triangular capsules grow at the end of short, lime green sporophytes, eventually opening up during the early winter to release millions of spores; it does not cause any allergic reactions.
