Polytrichastrum formosum

Polytrichastrum formosum, commonly known as the bank haircap moss, is a species of moss belonging to the family Polytrichaceae. It has a cosmopolitan distribution, found mostly in temperate latitudes in the Northern Hemisphere and especially dominant in Europe and North America. However, it has also been identified in India, China, Nepal, Japan, Algeria, Australia, New Zealand, Russia, Turkey, Syria, and the Atlantic islands (i.e. Iceland). This species was previously called Polytrichum formosum but has been reclassified as Polytrichastrum formosum due to distinct sporangial features. Recent molecular studies suggest that it should be moved back to its original genus (Polytrichum), however bryologists have not yet reached a consensus....read more on Wikipedia.
