Discussion
A locally abundant (T. T. McIntosh 1989) western species, Pterygoneurum kozlovii commonly grows mixed with other species of the genus. Although the gametophyte is much the same as that of P. subsessile, the brown, spheric cleistocarpous capsules with no annulus are unique for the genus. Perigonia are borne terminally on short lateral or basal branches.
