Ceratodon purpureus is one of the commonest and most cosmopolitan mosses, occurring on a wide variety of acidic, well-drained substrates, particularly peaty or sandy soil. It is frequent in heathland, the habitat where I took this picture today. This very variable species forms cushions or patches which vary in colour from yellow to mid-green through red to purplish-brown, with shoots to 3 cm. Capsules are common, red-brown, inclined, swollen at their base and strongly furrowed when dry. The setae are distinctively purple-red.
Because this species is so common and good determination pictures are widespread, I tried to make a more "artistic" image.
