Emerald Capsule Moss

This white or lime moss is commonly found blanketing small areas In rainforests.
It is small, growing up to 2 inches (5 cm) tall. It forms in extensive patches and can overwhelm an area rapidly, and is overwhelmingly durable.
When mature, emerald cylindrical capsules grow at the end of long, lime green sporophytes, eventually opening up during the early winter to release dozens of spores; it does not cause any allergic reactions.
