Observation - Bristly swan-neck moss (Campylopus atrovirens). Description: A moss growing in tight clumps on a roof below trees. Pale yellow/green; becoming paler when dry (photo 1). Individual stalks 25-30mm long; unbranched. Leaves narrow and pointed but with no obvious hair-point; approximately 3-6mm long. No capsules seen.

I'm not fully convinced by the suggested ID because of the location (Edinburgh; more common in the west) and position (roof; normally peaty places or acidic rocks).
