Silverfern

This silver moss is commonly found growing in giant clumps In rainforests, On trees, and In moorlands.
It is small, growing up to 2 inches (5 cm) tall. It forms in large clumps, and is extremely flimsy; it dislikes being stepped on.
When mature, emerald shield-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the late autumn to release thousands of spores.
