Brown Velvet Moss

This brown moss is commonly found blanketing medium-sized areas On trees, In bogs, and In heathlands.
It is big, growing up to 10 inches (25 cm) tall. It forms in sparse patches and they spread and grow quickly, and is overwhelmingly frail.
When mature, emerald oval-shaped capsules grow at the end of long, lime green sporophytes, eventually opening up during the late summer to release hundred of spores; it can cause severe allergic reactions.
