Calypogeia neesiana


Calypogeia neesiana is a rare leafy-liverwort. It is distinguished from other species in the genus by the leaf apices, which are truncate; in other words, they look like the tips were cut off.

Habitat and Distribution

Calypogeia neesiana can be found on acid substrates, such as peat (amongst Sphagnum), humus and decaying logs.

Calypogeia neesiana has been reported from Gloucester and Kings Counties in New Brunswick, but the Kings county record may have been a misidentification of a mixed colony (including C. muelleriana and C. fissa); no other records are currently archived at an indexed herbarium. While it is apparently rare, it is also likely underreported, due to the combination of diminuitive size, and because it is sometimes found growing intermixed with other members of the genus. It is also reported from Quebec (Faubert 2012), Maine (Schuster 1969), and Nova Scotia (Brown 1936).
