Emerald Clump Moss

This green moss is commonly found growing in medium-sized clumps In rainy mountain ranges, On trees, and In heathlands.
It is average-sized, growing up to 6 inches (15 cm) tall. It forms in thick clumps and they are slow to spread and grow, and is slightly resilient; it is very difficult to kill.
When mature, emerald circular capsules grow at the end of long, lime green sporophytes, eventually opening up during the late autumn to release thousands of spores; it does not cause any allergic reactions.
