Polytrichum piliferum, the bristly haircap, is an evergreen perennial species of moss in the family Polytrichaceae.[2] The bristly haircap moss is small-sized to medium-sized and forms loose tufts[3] with wine-reddish stems.[4] It is an acrocarpous moss that appears bluish-green to grey.[5] This moss grows in clumps on erect shoots and becomes a red-brown colour as it grows older.[6] The most distinguishing feature of P. piliferum is the long, white awn at the tips of the leaves, which also give this moss its grey colour.[5] It is the only species in its genus where the awn is completely hyaline.[6]
