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]
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 leucocysts. The bubbles are theorized to be necessary for the function of the chlorocysts 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]

Funaria is a genus of approximately 210 species of moss. Funaria hygrometrica is the most common species. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. The name is derived from the Latin word “funis”, meaning "a rope". In funaria root like structures called rhizoids are present.
Dicranum is a genus of mosses, also called wind-blown mosses or fork mosses. These mosses form in densely packed clumps. Stems may fork, but do not branch. In general, upright stems will be single but packed together. Dicranum is distributed globally. In North America these are commonly found in Jack pine or Red pine stands.
Lepidopilum is a genus of moss in family Pilotrichaceae. There are over 200 species in the genus.
Dicranaceae is a family of haplolepideous mosses (Dicranidae) in class Bryopsida. Species within this family are dioicous. Genera in this family include Dicranum, Dicranoloma, and Mitrobryum.
Leucobryaceae is a family of haplolepideous mosses (Dicranidae) in the order Dicranales.
Grimmia is a genus of mosses (Bryophyta), originally named by Jakob Friedrich Ehrhart in honour of Johann Friedrich Carl Grimm, a physician and botanist from Gotha, Germany.
Barbula is a genus of mosses in the family Pottiaceae.
Ditrichum is a genus of haplolepideous mosses (Dicranidae) in the family Ditrichaceae.
Campylopus is a genus of 180 species of haplolepideous mosses (Dicranidae) in the family Leucobryaceae. The name comes from the Greek campylos, meaning curved, and pous, meaning foot, referring to the setae which curve downwards.
Thuidium is a genus of moss in the family Thuidiaceae. The name comes from the genus Thuja and the Latin suffix -idium, meaning diminutive. This is due to its resemblance to small cedar trees.
Neckera is a large genus of mosses belonging to the family Neckeraceae. The genus was first described by Johann Hedwig. The genus has a cosmopolitan distribution.
Rhynchostegium is a genus of pleurocarpous mosses belonging to the family Brachytheciaceae. The genus has a cosmopolitan distribution across different climatological regions except the polar regions, mostly in tropic to north temperate regions. The genus contains both aquatic and terrestrial species. The genus was named for their rostrate opercula. The type species of this genus is Rhynchostegium confertum (Dicks.) Schimp.
Isothecium is a genus of mosses belonging to the family Lembophyllaceae. The genus has a cosmopolitan distribution.
