Discussion
Myrinia pulvinata may be mistaken for species of Leskea because of similar habitat and leaf shape. Plants of Leskea generally have a much stronger costa as well as papillose laminal cells. When sporophytes are present, the cross striolate external exostome surface in Myrinia is distinctive. Myrinia pulvinata and Leskea polycarpa are often found growing intertwined.
