Redshank Moss - Ceratodon purpureus

    Description

    This very variable species forms cushions or patches which vary from yellow to mid-green through red to purplish-brown, with shoots to 3 cm. The leaves are typically 1.5 to 2 mm long, narrowly triangular, the lower ones appressed to the stem, the upper somewhat twisted and wavy when dry, normally held away from the stem or slightly reflexed when moist. The leaf margins are recurved almost from the base to the tip. The nerve is stout and ends in the tip of the acutely pointed leaf, which usually has a few coarse teeth. Capsules are common, red-brown, inclined when mature, swollen at the base and strongly furrowed when dry. The setae are distinctively purple-red.
