Emerald Marsh Moss

This gray-green moss is commonly found blanketing medium-sized areas On trees, and In marshes.
It is average-sized, growing up to 5 inches (13 cm) tall. It forms in sparse patches and they are exceptionally hardy, and is overwhelmingly flimsy; it struggles more than most during dry spells.
When mature, emerald oval-shaped capsules grow at the end of elongated, lime green sporophytes, eventually opening up during the late summer to release thousands of spores; it does not cause many allergic reactions.
