Pseudoditrichales
Pseudoditrichales is an order of haplolepideous mosses in the subclass Dicranidae. It comprises two families, Pseudoditrichaceae and Chrysoblastellaceae. Pseudoditrichaceae was previously placed in Bryales, while Chrysoblastellaceae is a new family erected for ''Chrysoblastella'', which was previously placed in Ditrichaceae Ditrichaceae is a family of haplolepideous mosses (Dicranidae) in the order Dicranales.

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.

Pseudoditrichaceae
''Pseudoditrichum'' is a rare North American genus of haplolepideous moss (Dicranidae). It is the only known genus in its family (Pseudoditrichaceae), and there is only one species in the genus. ''Pseudoditrichum mirabile'' has been found only in a small area along the Sloan River near Great Bear Lake Great Bear Lake ( den, Sahtú; french: Grand lac de l'Ours) is a lake in the boreal forest of Canada. It is the largest lake entirely in Canada (Lake Superior and Lake Huron are larger but straddle the Canada–US border), the fourth-largest .... This is in the Northwest Territory in northern Canada, only a few kilometers south of the Arctic Circle. ''Pseudoditrichum mirabile'' is unusual in that the combination of the gametophyte features and the sporophyte morphology do not match any other moss family. The entire plant is a mere 3 mm tall, growing on moist silt, generally underneath '' Populus''. It spreads vegetatively by means of spherical underground tubers as w ...

Chrysoblastellaceae
''Chrysoblastella'' is an genus of Peristome#In_mosses, haplolepideous mosses (Dicranidae) in the monotypic family Chrysoblastellaceae. The genus was previously placed in the family Ditrichaceae.

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

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, 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) 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 termed arthrodontous and is found in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise 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 leaves that are generally only one cell thick, attached to a 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 spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Bryales
Bryales is an order (biology), order of mosses. Taxonomy The order Bryales includes the following five family (biology), families: * Bryaceae * Leptostomataceae * Mniaceae * Phyllodrepaniaceae * Pulchrinodaceae The order used to be defined broadly to include the Rhizogoniales, but is now used in a narrower sense.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). . A species of the Mniaceae genus ''Rhizomnium'', ''Rhizomnium dentatum'', was described from fossil gametophytes preserved in Baltic amber. The families Catoscopiaceae and Pseudoditrichaceae were previously placed in Bryales, but are now placed in Dicranidae as part of an early branching grade.
