Archegoniate plants of 1-stratose, ovate to ovatelanceolate leaves, leaves with ciliate or jagged margins. Seta erect, rough, redbrown when mature, 3–15 mm, bulging where it joins the oblique capsule.

Distribution

North America, Europe, Asia, Pacific Islands (New Zealand), Australia

Discussion

Species 12 (4 in the flora).

Buxbaumia plants are unlikely to be seen unless sporophytes are present. No other genus in North America is likely to be confused with it, as the characteristic obliquely oriented sporangium on erect rough seta makes it distinctive. Sporophytes appear in fall, capsules mature in spring.

Selected References

None.
