This copper moss is commonly found growing in large clumps In rainforests, On rotten logs, and In rainy mountain ranges.
It is massive, growing up to 1.5 feet (46 cm) tall. It forms in large clumps and they overwhelm an area rapidly, and is very strong.
When mature, emerald spiral capsules grow at the end of long, lime green sporophytes, eventually opening up during the early summer to release dozens of spores.
