Emerald

This lime green moss is commonly found growing in tiny clumps In damp forests, and In rainy mountain ranges.
It is small, growing up to 1 inch (3 cm) tall. It forms in large clumps, and is overwhelmingly sturdy.
When mature, emerald oval-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the late autumn to release thousands of spores; it can cause severe allergic reactions.
