Common Haircap

The common haircap, <em>Polytrichum commune</em>, is a moss belonging to the family Polytrichaceae, one of the largest and most structurally complex families within the division Bryophyta. This species is widely distributed across Asia, Europe, North America, and South America, making it one of the most cosmopolitan mosses in the world. <em>Polytrichum commune</em> is typically found in moist to wet habitats including bogs, fens, wet heathlands, and the margins of streams and woodland ponds. It is characterized by its tall, upright gametophytes, which can reach several centimeters in height, and its distinctive star-shaped arrangement of leaves when dry. The species is assessed as Least Concern on the IUCN Red List. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
