Pohlia wahlenbergii Pale Glaucous Thread-moss

A very pale, glaucous-green, dioicous acrcarpous moss which grows in damp or wet places along tracks, ditches and on rocks particularly if they are irrigated by trickles of water. The pale, sometimes almost white, loose cushions with reddish stems are usually very distinctive but it is sometimes confused with Pohlia melanodon, although that species is never glaucous. It is found throughout western and northern Britain but it is much less common in the east. It is very common in Wales and in the uplands of West Glamorgan, where it is found frequently in the moist, gritty edges of forest roads. Sporophyte capsules are rare.
