Taller and seems to stand up straighter than Wood Hair-Moss.

Stems rigid rather than floppy, with long narrow leaves tapering to a point. The moss is surrounded by the lime-green/yellow feathery moss called Step Moss.

It has a two tier nature, with new growth growing out of the 'cup' on older brown growth from previous year(s). Note the 'cup' atop the new growth also. Can it be three tiered?

Leaves in whorls up the stem. They stick out straight when moist, and close to the stem when dry. Male 'flower' atop.

 The male 'flower' forms from modified leaves at the top of the plant and has pentagonal symmetry. It is light green, un-like the purple/red ones of Bristly Haircap Moss.

A brief stop on a very long walk from Ravenglass to Silecroft over as many hills and bogs as could be found on the way. These were in a marshy saddle between two summits.

The capsules are cylindrical with pointy tops and conical bottoms.

The capsules are covered in very fine yellowish hairs.

Each leafy stalk seems to have a tapered axle protruding from the top: two leaves back to back pointing straight upwards.


Some similarities to : Wood Hair-Moss but that is less tall, is more floppy, with leaves of unequal length and closer together, and its leaves are more curved when moist and they do not have light glossy sheaths.

No relation to : Moss Campion or Mossy Saxifrage [plants with similar names].

Marsh Hair-Moss inhabits wet woodland in particular, but also wet heaths, bogs and damp moors. It often grows with Sphagnum Moss (but not in these photographs) and beside watercourses in woodlands.
