Emerald

This gray-green moss is commonly found blanketing giant areas On trees, In rainforests, and In rainy mountain ranges.
It is average-sized, growing up to 4 inches (10 cm) tall. It forms in small clumps and they spread and grow quickly, and is very durable; it can easily endure being trodden on.
When mature, emerald kidney-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the mid-autumn to release hundred of spores.
