Emerald

This yellow-green moss is commonly found blanketing tiny areas In damp forests, In rainy mountain ranges, and On trees.
It is small, growing up to 1 inch (3 cm) tall. It forms in small clumps and they spread and grow quickly, and is slightly flimsy; it struggles more than most during dry spells.
When mature, emerald teardrop-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the late autumn to release hundred of spores; it does not cause any allergic reactions.
