Springy Turf-moss (Rhytidiadelphus squarrosus)

Observation - Springy Turf-moss (Rhytidiadelphus squarrosus). Description: Can anyone help, please, with an ID for this moss? Growing on the ground. The grass (probably Poa annua) gives an idea of scale. Edit: Changed to match markwilson's ID. Many thanks.
