Discussion

Weissia inoperculata is known only from the type specimen (Stanford University, Santa Clara County). It has a gametophyte much like that of Trichostomum brachydontium and may prove better placed in Trichostomum. The operculum is weakly marked off by a ring of several rows of small cells.
