Sunset Moss

This orange-yellow moss is commonly found growing in medium-sized clumps In bogs.
It is huge, growing up to 1.0 foot (30 cm) tall. It forms in thick clumps and they overwhelm an area rapidly, and is slightly resilient.
When mature, emerald heart-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the mid-summer to release thousands of spores; it can cause severe allergic reactions.
