Leucobryum is a genus of haplolepideous mosses (Dicranidae) in the family Leucobryaceae. The name comes from the Greek leukos, meaning white, and bryon, meaning moss.[1]

Description[]

Leucobryum species are in found in erect, dense, and often rounded cushions. Their color varies from white to grayish or bluish-green. Species are characterized by having thick, whitish leaves with a large, expanded costa.[1] It has been suggested that the characteristic pale color exhibited by some species is caused by air bubbles in the . The bubbles are theorized to be necessary for the function of the for the purpose of gas exchange.[2]

Species are dioecious, with male plants stunted and found growing among the leaves of the female plants. Sporophytes are rare.[3]

There are approximately 122 species of Leucobryum worldwide. Only two species are known to occur in North America.[1]
