Species description: Species name meaning of the marshes, in reference to the usual habitat.
Reproduction: Sporophytes sporadic in occurrence, maturing in spring to summer, reddish-brown and grooved when mature; gemmiferous plants frequent through most of the year.
Distinguishing characteristics: The whitish midrib that is shiny on the back of the leaf is distinctive in dried plants; the leaves are somewhat contorted when dry.
Habit: Forming extensive dense, yellow-green turfs of erect shoots, often interwoven with red rhizoids.
Similar Species: Differs from A. androgynum in habitat and size. From A. turgidum, the contorted leaves and the less turgid shoots are useful distinguishing features; A. turgidum also occurs in drier sites. A. acuminatum has pointed leaves but the plants are turgid and leaves do not become contorted when dry.
Habitat / Range
Frequent in swampy, boggy, or seepage sites; on lake and pond margins and on cliff shelves; occasionally on rotten logs, from sea level to alpine elevations
