Status: Native
Synonyms:
Didymodon brachydontius (Bruch) Wilson
Mollia brachydontia (Bruch) Lindb.
Tortella brachydontia (Bruch) C.E.O. Jensen
Tortula brachydontia (Bruch) Mitt.
Trichostomum does not have the wide bands of hyaline cells running up the margin above
the base as in Tortella. Differentiating Trichostomum from Weissia can be
difficult. Trichostomum generally has longer leaves and are frequently
somewhat undulate along the margin. Trichostomum brachydontium in particular has a very
stout mucro that can consist of more than 6 cells. It does not have a dilated base.
Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp, and Dina Clark for permitting
us to photograph this specimen.
