Golden Moss

This orange-yellow moss is commonly found blanketing small areas On trees, and In damp forests.
It is modest-sized, growing up to 5 inches (13 cm) tall. It forms in sparse patches and they overwhelm an area rapidly, and is very robust.
When mature, emerald shield-shaped capsules grow at the end of elongated, lime green sporophytes, eventually opening up during the late autumn to release thousands of spores.
