Bog Groove-moss - Aulacomnium palustre

    Description

    Aulacomnium palustre forms tufts 3 to12 cm tall, with pale yellow-green leaves that contrast strongly with the ginger-brown, felt-like rhizoids which cover the stem. Shoots occasionally terminate in an elongated stalk with a terminal cluster of gemmae. When dry, the leaves become somewhat crisped and twisted. The leaves are 4 to 6 mm long near the top of the shoot, but shorter below, spearhead-shaped, shortly pointed, matt and pale yellow-green. Curved, furrowed capsules 2.5 mm long are produced occasionally.
