Emerald

This yellow-green moss is commonly found blanketing tiny areas In moorlands.
It is enormous, growing up to 1.2 feet (36 cm) tall. It forms in thin clumps, and is slightly resistant; it can easily endure flooding and draughts.
When mature, emerald V-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the early winter to release dozens of spores; it does not cause many allergic reactions.
