Emerald Clump Moss

This green and lime green moss is commonly found growing in giant clumps In rainforests, In moorlands, and On trees.
It is large, growing up to 7 inches (18 cm) tall. It forms in thin clumps and they spread and grow quickly, and is overwhelmingly tough; it is very difficult to kill.
When mature, emerald oval-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the early autumn to release millions of spores; it can cause severe allergic reactions.
