    The erect, fragile leaves differ from those of O. erectifolium in being dull and considerably shorter. The costa is elliptic rather than terete in section.

    The genus Leucophanes Brid. occurs in Costa Rica, as L. calymperatum C. Müll. (syn. L. mitteniiCard. ex Par.) and can be expected in Mexico. The plants are similar to Leucobryum but quite shiny when dry, and the leaves have a median, costa-like stereid band as well as a thickened stereid border. [It may be that this species should be referred to the African L. molleri C. Müll.]
