Neckera Pennata
''Neckera pennata'' is a species of moss belonging to the family Neckeraceae. It has 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 ext .... Feather flat moss can be an indicator of late successional and old-growth hardwood forests, because it usually grows on sugar maples in the Northeast that are at least 120 years old.

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 ...

Neckeraceae
Neckeraceae is a moss family in the order Hypnales. There are about 200 species native to temperate and tropical regions. Most grow on rocks, or other plants. Description Members of the family are usually large and glossy plants with creeping stolons that bear small leaves and tufts of rhizoids. Stems are generally frondose, but may rarely be dendroid. Leaf cell shape is almost always smooth, short, and firm-walled. Marginal cells are typically quadrate to short-rectangular in few to several rows. The sporophyte features are variable between genera. Species are epiphytic, epilithic, or aquatic.Olsson, S, Buchbender, V, Enroth, J, Huttunen, S, Hedenäs, L & Quandt, D 2009, 'Evolution of the Neckeraceae (Bryophyta): resolving the backbone phylogeny', Systematics and Biodiversity, vol 7, no. 4, pp. 419-432. Classification The Neckeraceae were originally placed within the Leucodontales. However, they are now included in the Hypnales. The following genera Genus ( plural genera ) ...

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 ...
