Chestnut

This brown moss is commonly found blanketing tiny areas In marshes, and In rainforests.
It is enormous, growing up to 1.3 feet (41 cm) tall. It forms in extensive patches, and is overwhelmingly flimsy; it burns easily in strong sunlight.
When mature, emerald crescent-shaped capsules grow at the end of short, lime green sporophytes, eventually opening up during the early summer to release millions of spores.
