Trichostomum , also called hair mouth Moose, is a genus of mosses from the family pottiaceae .
description
The plants of this genus are about 0.5 to 4 centimeters tall and form loose to dense lawns. They grow upright and are simple or branched. The leaves are lanceolate to tongue-shaped, blunt to pointed, the leaf margins entire to crenulated, flat or in the upper part of the leaf upright to inflected. The strong vein extends to the tip of the leaf or emerges as a short spike tip. When moist, the leaves are upright to protruding, and when dry, they are crinkled. The leaf cells are rectangular, smooth and transparent at the base, square round to short rectangular in the upper leaf section, papillary and opaque.
The species are usually diocesan . An upright seta carries the mostly upright, rarely slightly inclined, cylindrical to ellipsoidal spore capsule. The thread-like peristome teeth are upright or slightly twisted. The kalyptra is hood-shaped, the capsule lid is tapered to beaked. In a few species the spore capsule is celistocarp or the peristome is rudimentary to absent.
