Some similarities to : Common Haircap Moss aka Marsh Hair-Moss, but that doesn't have orange/red capsules, amongst other differences.

Bristly Haircap Moss prefers a drier acidic environment than Common Haircap Moss, and grows on boulders, disturbed acidic sands and gravels and on heaths in lowlands. It is common in upland areas with stony substrates such as the edges of paths, scree slopes, mountain ridge tops, singly river borders and lake or tarn margins.

The ripe capsules (not shown) are produced in summer and are 4/5-angled born on reddish sets 1 to 3cm long.
