White Glowfern

This white moss is commonly found blanketing large areas In moorlands.
It is average-sized, growing up to 5 inches (13 cm) tall. It forms in small clumps and they are slow to spread and grow, and is very light; it burns easily in strong sunlight.
When mature, emerald triangular capsules grow at the end of short, lime green sporophytes, eventually opening up during the early autumn to release thousands of spores.
