Fissidens limbatus[4] commonly known as Herzog's pocket-moss, is a moss in the family Fissidentaceae.

This species is found growing in high elevations in tropical America (especially along the coastal regions of Bolivia[5]) in addition to the US, Mexico and Canada.

[6] The sporangium capsule is very tiny 0.6–1 mm long that is erect or sometimes lightly curved, resembling a shape of an ellipsoid.

The immature capsule of F. limbatus is green, and the operculum is fully and prominently enlarged above the annulus.

[6] Peristomal teeth are present with 21–55.5 μm width at the opening of the capsule with filaments that are somewhat papillose and helical thickenings[6] The species grows in shaded, basic to slightly acidic environment on banks or mineral soil.

F. limbatus sometimes grows directly on rocks in sheltered but not wet sites at elevations up to about 1000m.

[10] In North America, this moss can be found along the western coast of the US, Canada and Mexico.
