Emerald

This emerald moss is commonly found growing in small clumps In heathlands, In marshes, and In rainy mountain ranges.
It is short, growing up to 2 inches (5 cm) tall. It forms in thick clumps, and is very frail; it struggles more than most during dry spells.
When mature, emerald kidney-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the mid-summer to release thousands of spores; it can cause allergic reactions.
