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.
