Emerald

This slate moss is commonly found growing in tiny clumps In marshes, and In moorlands.
It is average-sized, growing up to 4 inches (10 cm) tall. It forms in thick clumps and they spread and grow quickly, and is slightly resistant.
When mature, emerald triangular capsules grow at the end of short, lime green sporophytes, eventually opening up during the mid-summer to release thousands of spores; it does not cause many allergic reactions.
