Woolly Fringe-moss - Racomitrium lanuginosum

Found on Dartmoor this common species is quite forward to identify. Under the microscope the long wavy cells identify the group as Racomitrium. Grimmia also has wavy cells but these are short. Racomitrium lanuginosum has 90 degree projections on the white hair point which is visible with a high powered magnifying glass.
