Polytrichum
''Polytrichum'' is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that cover a cosmopolitan distribution. The genus ''Polytrichum'' has a number of closely related sporophytic characters. The scientific name is derived from the Ancient Greek words ''polys'', meaning "many", and ''thrix'', meaning "hair". This name was used in ancient times to refer to plants with fine, hairlike parts, including mosses, but this application specifically refers to the hairy calyptras found on young sporophytes. A similar naming related to hair appears in Old Norse, ''haddr silfjar'', "hair of Sif", goddess from Norse Mythology, wife of the god Thor. There are two major sections of ''Polytrichum'' species. The first — section ''Polytrichum'' — has narrow, toothed, and relatively erect leaf margins. The other — section ''Juniperifolia'' — has broad, entire, and sharply inflexed leaf margins that enclose the lamellae on the upper lea ...

Polytrichum Commune
''Polytrichum commune'' (also known as common haircap, great golden maidenhair, great goldilocks, common haircap moss, or common hair moss) is a species of moss found in many regions with high humidity and rainfall. The species can be exceptionally tall for a moss with stems often exceeding though rarely reaching , but it is most commonly found at shorter lengths of . It is widely distributed throughout temperate and boreal latitudes in the Northern Hemisphere and also found in Mexico, several Pacific Islands including New Zealand, and also in Australia. It typically grows in bogs, wet heathland and along forest streams. Description ''Polytrichum commune'' is a medium to large moss. It is dark green in colour, but becomes brownish with age. The stems can occur in either loose or quite dense tufts, often forming extensive colonies. The stems are most typically found at lengths of 5 to 10 cm, but can be as short as 2 cm or as long as 70 cm. They range in stiffness f ...

Polytrichum Formosum
''Polytrichastrum formosum'', commonly known as the bank haircap moss, is a species of moss belonging to the family Polytrichaceae. It has a cosmopolitan distribution, found mostly in temperate latitudes in the Northern Hemisphere and especially dominant in Europe and North America. However, it has also been identified in India, China, Nepal, Japan, Algeria, Australia, New Zealand, Russia, Turkey, Syria, and the Atlantic islands (i.e. Iceland). This species was previously called ''Polytrichum formosum'' but has been reclassified as ''Polytrichastrum formosum'' due to distinct sporangial features. Recent molecular studies suggest that it should be moved back to its original genus (''Polytrichum''), however Bryology, bryologists have not yet reached a consensus.   Habitat ''Polytrichastrum formosum'' generally inhabits shaded, poor soils and humus in damp coniferous forests and cool temperate rainforests. This species is most common in Europe and grows in grasslands, lowland h ...

Polytrichum Alpinum
''Polytrichum alpinum'', also known as Alpine haircap, is a species of moss from the family Polytrichaceae. It is widely distributed and may be found growing among other moss species. Description ''Polytrichum alpinum'' grows to form a loose, muddy green or bluish-green to brownish lawn. Typically, it grows up to high. The upright to erect stems often carry tufted branches of equal length above. In the lower part of the stems, leaves are small and scale-like, but become larger in the upper stem section – usually 7–10 mm long. The broad-oval, yellowish to brownish sheath at the leaf base is linear-lanceolate and occupies less than a third of the total leaf length. Leaf edges are serrated, fitting together when dry and bending back and protruding when wet. The leaf rib is cut in the upper part, emerging from the back as a short spike from the blade tip. The spreading part of the leaf is covered with numerous lamellae (up to 40), these are in the middle of the leaf, ...

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 ...
