Marshy Emerald Moss

This yellow-green moss is commonly found blanketing tiny areas In marshes.
It is average-sized, growing up to 5 inches (13 cm) tall. It forms in small clumps and they are slow to spread and grow, and is slightly flimsy.
When mature, emerald oblong capsules grow at the end of short, lime green sporophytes, eventually opening up during the early summer to release dozens of spores; it does not cause any allergic reactions.
