Emerald

This yellow-green moss is commonly found growing in medium-sized clumps In moorlands, In marshes, and In rainforests.
It is short, growing up to 3 inches (8 cm) tall. It forms in sparse patches and they spread and grow quickly, and is overwhelmingly strong.
When mature, emerald cylindrical capsules grow at the end of elongated, lime green sporophytes, eventually opening up during the mid-summer to release millions of spores; it can cause severe allergic reactions.
