Seligeria recurvata is disjunct in Washington and southern British Columbia to eastern Canada south to Tennessee and west to Michigan. It is distinguished by the combination of cyneous seta, oblong rather narrow capsules, and subulate leaves with the costa filling the apex. Seligeria campylopoda has similar sporophytic features, but has broader leaves with the costa ending in, but not filling, the apex. The spores of both species are small.
