Sunburst Moss

This yellow moss is commonly found growing in tiny clumps In heathlands, and On rotten logs.
It is large, growing up to 8 inches (20 cm) tall. It forms in sparse patches, and is overwhelmingly delicate.
When mature, emerald heart-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the mid-autumn to release thousands of spores.
