Bryopsida
The Bryopsida constitute the largest class of mosses, containing 95% of all moss species. It consists of approximately 11,500 species, common throughout the whole world. The group is distinguished by having spore capsules with teeth that are ''arthrodontous''; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule.Buck, William R. & Bernard Goffinet. (2000) "Morphology and classification of mosses", pages 71-123 ''in'' A. Jonathan Shaw & Bernard Goffinet (Eds.), ''Bryophyte Biology''. (Cambridge: Cambridge University Press). Consequently, mosses in the Class Bryopsida are commonly known as the “joint-toothed” or “arthrodontous” mosses. These teeth are exposed when the covering operculum falls off. In other groups of mosses, the capsule is either ''nematodontous'' with an attached operculum, or else splits open without operculum or teeth. Morphological groups The Bryopsida can be simplified into three groups: the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buxbaumiidae
''Buxbaumia'' (bug moss, bug-on-a-stick, humpbacked elves, or elf-cap moss) is a genus of twelve species of moss (Bryophyta). It was first named in 1742 by Albrecht von Haller and later brought into modern botanical nomenclature in 1801 by Johann Hedwig to commemorate Johann Christian Buxbaum, a German physician and botanist who discovered the moss in 1712 at the mouth of the Volga River. The moss is microscopic for most of its existence, and plants are noticeable only after they begin to produce their reproductive structures. The asymmetrical spore capsule has a distinctive shape and structure, some features of which appear to be transitional from those in primitive mosses to most modern mosses. Description Plants of ''Buxbaumia'' have a much reduced gametophyte, bearing a sporophyte that is enormous by comparison. In most mosses, the gametophyte stage of the life cycle is both green and leafy, and is substantially larger than the spore-producing stage. Unlike these other mos ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dicranidae
The Dicranidae are a widespread and diverse subclass of mosses in class Bryopsida, with many species of dry or disturbed areas. They are distinguished by their spores; the peristome Peristome (from the Greek ''peri'', meaning 'around' or 'about', and ''stoma'', 'mouth') is an anatomical feature that surrounds an opening to an organ or structure. Some plants, fungi, and shelled gastropods have peristomes. In mosses In mosses, ... teeth are haplolepideous with a 4:2:3 formula, and an exostome is absent.

Funariidae
The Funariidae are a widespread group of mosses in class Bryopsida.Buck, William R. & Bernard Goffinet. 2000. "Morphology and classification of mosses", pages 71-123 ''in'' A. Jonathan Shaw & Bernard Goffinet (Eds.), ''Bryophyte Biology''. (Cambridge: Cambridge University Press). . The majority of species belong to the genera '' Funaria'' (c. 200 species) and '' Physcomitrium'' (c. 80 species). Classification The Funariidae include three monotypic orders, with around 350 species, most of which belong either to the genus ''Funaria'' or ''Physcomitrium''. : Order Encalyptales :: Family Encalyptaceae (2 genera, 35 species) : : Order Funariales :: Family Funariaceae (14 genera, ca. 300 species) : : Order Disceliales :: Family Disceliaceae (1 species ''Discelium nudum'') Description Species in the subclass Funariidae typically live on or near the ground.

Diphysciidae
''Diphyscium'' is a genus of mosses in the family Diphysciaceae. Members of this genus are small, perennial plants. The capsule does not elongate much, and remains buried among surrounding leaves. There are fifteen species of ''Diphyscium''. However, two of these species formerly were placed in the southeast Asian genus ''Theriotia'', and one species, from Chile Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east a ..., formerly was segregated in the monotypic genus ''Muscoflorschuetzia''. In 2003, Magombo proposed reclassifying all fifteen species as belonging to the single genus ''Diphyscium''. References Moss genera Bryopsida {{Bryophyte-stub ...

Polytrichopsida
Polytrichaceae is a common family of mosses. Members of this family tend to be larger than other mosses with a thickened central stem and a rhizome. The leaves have a midrib that bears photosynthetic lamellae on the upper surface. Species in this group are dioicous. Another characteristic that identifies them is that they have from 32 to 64 peristome teeth in their sporangium.

Tetraphidopsida
Tetraphidaceae is a family of mosses. It includes only the two genera '' Tetraphis'' and '' Tetrodontium'', each with two species. The defining feature of the family is the 4-toothed peristome. Range This family of mosses is most commonly found in northern latitudes. ''Tetraphis'' ''Tetraphis pellucida'' is the most common species in the family and is usually found in deciduous forests. Its leaves become wider in colder climates, which often leads to a misclassification of the species. ''Tetraphis geniculata'' is less commonly found and also appears in northern latitudes. The species often grows alongside the only other species in the genus, ''T. pellucida''. Both ''Tetraphis'' species are found growing on moist sedimentary rocks and also on soil with high organic content, but the genus is mostly found growing on rotting logs. ''Tetrodontium'' '' Tetrodontium brownianum'' grows most frequently on wet and shady rocks, of either granite or sandstone. The species normally ...

Oedipodiopsida
''Oedipodium'' is the only genus of moss in the family Oedipodiaceae. It contains the single species ''Oedipodium griffithianum'', the gouty-moss or Griffith's oedipodium moss. This species is distributed in cooler climates of Eurasia, as well as from Alaska, Washington state, British Columbia, Yukon, Greenland, Newfoundland, Tierra del Fuego and the Falkland Islands. The relationship of ''Oedipodium'' to other mosses has been much debated. Previously, the taxon has been included with the Funariales or the Splachnales. However, characteristics of the protonema A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage of development of the gametophyte (the haploid phase) in the life cycle of mosses. When a moss first grows from a spore, it starts as a ''germ tube'', ...ta and asexual propagation, along with molecular evidence, point to a closer relationship with the Tetraphidaceae.
