Emerald

This yellow-green moss is commonly found growing in tiny clumps In rainforests, In heathlands, and In damp forests.
It is average-sized, growing up to 5 inches (13 cm) tall. It forms in thin clumps and they spread and grow quickly, and is extremely strong.
When mature, emerald triangular capsules grow at the end of short, lime green sporophytes, eventually opening up during the late autumn to release dozens of spores.
