Embermoss

This orange moss is commonly found growing in medium-sized clumps In bogs.
It is small, growing up to 2 inches (5 cm) tall. It forms in thick clumps and they overwhelm an area rapidly, and is overwhelmingly sturdy; it can easily endure flooding and draughts.
When mature, emerald circular capsules grow at the end of short, lime green sporophytes, eventually opening up during the early summer to release thousands of spores; it can cause severe allergic reactions.
