Emerald

This gray-green moss is commonly found blanketing medium-sized areas On rotten logs, On trees, and In rainforests.
It is short, growing up to 2 inches (5 cm) tall. It forms in thick clumps, and is overwhelmingly frail; it struggles more than most during dry spells.
When mature, emerald spiral capsules grow at the end of elongated, lime green sporophytes, eventually opening up during the mid-autumn to release thousands of spores.
