Discussion:

Pseudopohlia is a genus four species, three of which Andrews (1950) suggested may be identical. The genus has an unusual peristome. Its exostome teeth are pale, papillose below, vertically striate above, and united in pairs. The endostome is irregularly developed with a low basal membrane and poorly differentiated cilia and segments. Other distinctive features of Pseudopohlia include the presence of bulbil-form gemmae in the leaf axils, well-differentiated basal leaf cells, long, flexuose setae, low (nearly flat) opercula, and coarsely papillose spores.  Pseudopohlia is gametophytically and sporophytically close to Pohlia subgenus Nyholmiella.
