Leucobryaceae is a family of haplolepideous mosses (Dicranidae) in the order Dicranales.[1][2]

Description[]

Members of the family grow small to large cushions. Species are characterized by having thick, whitish leaves with a large, expanded costa.[3] It has been suggested that the characteristic pale color exhibited by some species is caused by air bubbles in the , and the presence of air in the leaf is assumed characteristic of the Leucobryaceae.[4]

Classification[]

The Leucobryaceae have been sometimes included in the Dicranaceae because of similar costa and peristome structures.[3]

The number of genera assigned to the family has been subject to much debate and has ranged from one to fourteen.[3][5] Some genera previous assigned to Leucobryaceae have been split off into the family Calymperaceae, while molecular analyses have led to other changes, with other genera from Dicranaceae included.[5]

The family currently includes twelve genera:[1][2]
