Pleurozium Schreberi
''Pleurozium schreberi'', the red-stemmed feathermoss or Schreber's big red stem moss, is a moss with a loose growth pattern. The root name ''pleuro'' comes from the Latin for ribs, possibly describing how the parts branch from the stem. The species occurs on the floor of the boreal forests of Canada, Scandinavia and northern Russia; an example of this occurrence is within the black spruce/feathermoss climax forest, sometimes having moderately dense overstory canopy and featuring a forest floor of feathermosses including, ''Hylocomium splendens'' and ''Ptilium crista-castrensis''.C. Michael Hogan. 2008''Black Spruce: Picea mariana'', GlobalTwitcher.com, ed.

Hypnales
Hypnales is the botanical name of an order of Bryophyta or leafy mosses. This group is sometimes called feather mosses, referring to their freely branched stems. The order includes more than 40 families and more than 4,000 species, making them the largest order of mosses. Description Hypnales are mosses with pinnately or irregularly branched, reclining stems, with varying appearances. The stem contains only a reduced central vascular bundle, which is seen as a recent derived trait in mosses. The stems are covered with paraphyllia or pseudoparaphyllia, reduced filamentous or scaly leaves. The ordinary stem leaves are ovate to lanceolate, often with leaf wing cells. The midvein is often limited to the lower half of the leaf blade, or has completely disappeared. The cells of the leaf blade are prosenchymatic, many times longer than wide, with pointed ends interlocking. The sporophyte consists of a regularly shaped sporangium on a long stalk or seta. The spores are distribut ...

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 ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
