Pottiaceae

Belongs within: Dicranideae.Contains: Trichostomum, Tortella, Bryoerythrophylleae, Leptodontieae, Barbula, Didymodon, Weissia, Hyophileae, Tortula, Acaulon, Phascum, Pottia, Syntrichia. The Pottiaceae is a large, diverse family of mosses found worldwide, divided between about eighty genera. Members of the family are commonly small and found in harsh environments such as rocks and disturbed soil, primarily in calcareous habitats. Members of… Continue reading Pottiaceae

Campylopus

Belongs within: Dicranaceae. Campylopus is a large genus of mosses found worldwide, with their highest diversity in mountainous regions of southern and tropical parts of the world. They are often robust and grow in wide patches, with relatively straight, rigid leaves (Dixon 1924). Species of the genus are often morphologically variable, making identification difficult. Features… Continue reading Campylopus

Fissidentaceae

Belongs within: Dicranideae.Contains: Fissidens section Fissidens, Fissidens section Serridium. Fissidentaceae is a family of mosses distinguished by the arrangement of the leaves, in two rows on opposite sides of the stem and overlapping at the base. Members of the genus Nanobryum were previously classified into a separate family, but are now regarded as reduced relatives… Continue reading Fissidentaceae

Dicranella

Belongs within: Dicranaceae. Dicranella is a genus of mosses found worldwide, most species of which are small with narrow, silky leaves (Dixon 1924). They can be distinguished from members of the related genus Dicranum by the relatively undifferentiated alar cells in their leaves. Characters (from Smith 2004): Usually dioicous. Leaves narrow, differentiated in sheathing base… Continue reading Dicranella

Leucobryum

Belongs within: Dicranideae. Leucobryum is a large genus of mostly tropical mosses that grow as compact cushions. The genus name (‘white moss’) is derived from the whitish appearance of the plants when dry, resulting from the presence of rows of colourless cells in the edge of the leaf. Notable species include L. albidum and L.… Continue reading Leucobryum

Erpodiaceae

Belongs within: Dicranideae. The Erpodiaceae are a family of mosses found primarily in tropical and subtropical parts of the world. Characters (from Pursell & Allen 2007): Plants small, prostrate, usually freely branched, usually in mats. Stems smooth, radiculose, rhizoids smooth, in clusters contiguous to leaf insertion on abaxial side; axillary hairs minute, 2-3 cells in… Continue reading Erpodiaceae

Ditrichaceae

Belongs within: Dicranideae. The Ditrichaceae are a family of mosses that are usually found growing directly on soil. They are distinguished from related families primarily by features of the peristome, the ring of teeth around the opening of the spore capsule, with the teeth generally divided into terete filaments and lacking pit-striations (Seppelt 2007). However,… Continue reading Ditrichaceae

Ephemeraceae

Belongs within: Dicranideae. The Ephemeraceae are a family of minute, morphologically reduced mosses, consisting of persistent protonemata from which the ephemeral plants grow when conditions permit. They are usually found in habitats that are marginal for other mosses, such as sunny patches (Bryan 2007). The capsule may be cleistocarpous as in species of Ephemerum or… Continue reading Ephemeraceae

Calymperaceae

Belongs within: Dicranideae. The Calymperaceae are a family of mosses found around the world, with their highest diversity in the tropics and subtropics. Calymperaceous mosses most often grow epiphytically or epixylically (on wood), but may also grow on rocks or on the ground. Major genera within the Calymperaceae include Calymperes, in which the calyptra is… Continue reading Calymperaceae

Dicranideae

Belongs within: Bryophyta.Contains: Pottiaceae, Erpodiaceae, Calymperaceae, Ephemeraceae, Fissidentaceae, Leucobryum, Dicranaceae, Ditrichaceae, Rhabdoweisiaceae, Trematodon, Seligeriaceae, Racomitrioideae, Grimmia, Schistidium. The Grimmiales is an order of mosses found growing on rocks. A close relationship between Ptychomitrium and Grimmiaceae, but not Scouleriaceae, is supported by molecular phylogenetic analysis (La Farge et al. 2000). Members of the Grimmiaceae usually grow in dense… Continue reading Dicranideae
