Emerald

This moss green moss is commonly found blanketing small areas In heathlands, In bogs, and In rainforests.
It is small, growing up to 1 inch (3 cm) tall. It forms in thin clumps and they overwhelm an area rapidly, and is extremely resistant; it can easily endure being trodden on.
When mature, emerald triangular capsules grow at the end of long, lime green sporophytes, eventually opening up during the early autumn to release millions of spores.
