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 ...

Moss
Mosses are small, non-vascular plant, non-vascular flowerless plants in the taxonomic phylum, division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Wilhelm Philippe Schimper, Schimp. 1879) may also refer to the parent group bryophytes, which comprise Marchantiophyta, liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaf, leaves that are generally only one cell thick, attached to a plant stem, stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing sporangium, spores. They are typically tall, though some species ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Their stems typically have a central strand differentiated from the surrounding cells. The peristome teeth of their sporang ...

Timmiales
''Timmia'' is a genus of moss. It is the only genus in the family Timmiaceae and order Timmiales.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 genus is named in honor of the 18th-century German botanist Joachim Christian Timm Joachim Christian Timm (7 December 1734 – 3 February 1805) was a German apothecary, mayor of Malchin, and a botanist with a particular interest in cryptograms.

Peristome
Peristome (from the Greek language, 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, the peristome is a specialized structure in the sporangium that allows for gradual spore discharge, instead of releasing them all at once. Most mosses produce a capsule with a lid (the operculum (botany), operculum) which falls off when the spores inside are mature and thus ready to be dispersed. The opening thus revealed is called the ''stoma'' (meaning "mouth") and is surrounded by one or two peristomes. Each peristome is a ring of triangular "teeth" formed from the remnants of dead cells with thickened cell walls. There are usually 16 such teeth in a single peristome, separate from each other and able to both fold in to cover the stoma as well as fold back to open the stoma. This articulation of the teeth is term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diphysciales
''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 western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes, Andes Mountains and the Paci ..., 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 {{Bryopsida-stub ...

''Catoscopium'' is a genus of haplolepidous mosses (Dicranidae) in the monotypic family Catoscopiaceae and order Catoscopiales. It contains only a single species, ''Catoscopium nigritum''. Taxonomy The family Catoscopiaceae has traditionally been considered part order Bryales. However, phylogenetic analyses have found ''Catoscopium'' to be the earliest branching group in Dicranidae, as part of a grade of protohaplolepidous lineages.

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 teeth are haplolepideous with a 4:2:3 formula, and an exostome is absent. Systematics Traditionally, the Dricanidae comprised about six to eight orders. However, phylogenetic analysis using molecular markers suggested that Dicranales was paraphyletic with respect to Pottiales Pottiales is an order (biology), order of mosses in the subclass Dicranidae. Classification The following families are recognised in ''Bryophyte Biology'': *Pottiaceae *Pleurophascaceae *Serpotortellaceae *Mitteniaceae Some other families .... A recently phylogenomic analysis led to a break-up of Dicranales and creation of a number of new small orders. The phylogenetic relationships recovered within Dicranidae are shown in the cladogram below. The orders Bryoxiphiales, Pseudoditrichales and Mitteniales were not ...
