It is widespread in Canada, Alaska, the northeastern United States, Greenland, Iceland, and northern Europe occasionally as far south as northern Italy.[3][4][5] DescriptionPtilidium ciliare grows in loose, reddish-brown to yellow-green tufts, with individual shoots up to 3 mm wide. Its stems are pinnate or bipinnate, with short stubby branching clusters of dense with overlapping leaves covering its stem. The leaves are up to 2.8 mm wide and 2.3 mm long, and the leaves are finely serrated or ciliated, the margins extended as fringe-like rows of thin teeth. The teeth make it difficult to see that the leaves are bilobed. Sexual reproductive structures are very rarely observed on this species.[5][6]HabitatPtilidium ciliare is commonly found in lowland to upland habitats such as acidic grassland, rocky slopes, cliff ledges, screes, wall tops, dwarf shrub heaths, bogs, sand dunes and heathy woodlands. It is usually seen growing amongst a mixture of other bryophyte species. Well-drained and acidic substrates are the preferred growth medium of this species. It rarely grows on fallen logs and branches.[5][6]Similar speciesStunted forms of P. ciliare could be mistaken for the species P. pulcherrimum, but P. pulcherrimum is smaller, and more compact, almost always growing closely to bark. Mastigophora woodsii is a more robust plant, with longer, attenuated branches on which the leaf size gradually tapers towards the tips.[6] References1. ^{{cite web|url=http://www.theplantlist.org/tpl/record/tro-35185906|title=Ptilidium ciliare (L.)
