Emerald

This lime moss is commonly found blanketing medium-sized areas In marshes, and On trees.
It is modest-sized, growing up to 3 inches (8 cm) tall. It forms in large clumps, and is very light; it takes a lot of damage when trodden on.
When mature, emerald crescent-shaped capsules grow at the end of elongated, lime green sporophytes, eventually opening up during the early autumn to release millions of spores; it does not cause many allergic reactions.
