Fissidens adianthoides, the maidenhair pocketmoss, is a moss in the family Fissidentaceae. It was first collected by Hedwig in 1801.
Harold Ernest Robinson was an American botanist and entomologist.
Ionactis, common name stiff-leaved asters or ankle-asters, is a small genus of plants belonging to the family Asteraceae. These aster-like plants are endemic to North America. One species is widespread across much of the eastern half of the continent, while two others are rare endemics with very restricted ranges.
Polytrichum commune 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 30 cm (12 in) though rarely reaching 70 cm (27.5 in), but it is most commonly found at shorter lengths of 5 to 10 cm. 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. Additionally, class Polytrichopsida has been shown to thrive in partially open habitats that have been recently disturbed by human activities or even livestock.
Meesia uliginosa, the broad-nerved hump-moss, is a rare moss of the Western U.S. It occurs all around the northern hemisphere in higher latitudes, and in some places is not as rare as in the Western U.S.
The Funariidae are a widespread group of mosses in class Bryopsida. The majority of species belong to the genera Funaria and Physcomitrium.
Tetraphidaceae is a family of mosses. It includes only the two genera Tetraphis and Tetrodontium, each with two species. The defining feature of the family is the 4-toothed peristome.
Bryaceae is a family of mosses.
Polytrichum is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that have 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 leaf surface.
Ptilidium is a genus of liverwort, and is the only genus in family Ptilidiaceae. It includes only three species: Ptilidium californicum, Ptilidium ciliare, and Ptilidium pulcherrimum. The genus is distributed throughout the arctic and subarctic, with disjunct populations in New Zealand and Tierra del Fuego. Molecular analysis suggests that the genus has few close relatives and diverged from other leafy liverworts early in their evolution.
Anomobryum julaceum, the slender silver-moss, is a species of bryophyte native to all continents except South America and Antarctica. A. julaceum is found widespread in the temperate regions of the Northern and Southern Hemispheres. Its capsules mature beginning in late fall and through the spring. It is most commonly found in wet crevices and on sandstone cliffs. Additional micro-habitats include tussock tundra with seeps and late snow melt areas and on granitic outcrops. In eastern North America it appears to be restricted to acid habitats, in the wet crevices of sandstone cliffs or other seepy niches. Overall, A. julaceum resembles species of the genus Pohlia, and its leaves are similar to those of Bryum argenteum; it can only be separated from Pohlia and Bryum using a microscope. Anomobryum julaceum can be distinguished from Bryum argenteum by its strongly julaceous, shiny leaves.
Plagiomnium affine, the many-fruited thyme-moss, is a species of thyme-moss found in old-growth boreal forests in North America, Europe and Asia, growing in moist, but not wet, basic to slightly acidic micro-habitats in woodland and in turf.
Splachnaceae is a family of mosses, containing around 70 species in 6 genera. Around half of those species are entomophilous, using insects to disperse their spores, a characteristic found in no other seedless land plants.
Pogonatum urnigerum is a species of moss in the family Polytrichaceae, commonly called urn haircap. The name comes from "urna" meaning "urn" and "gerere" meaning "to bear" which is believed to be a reference made towards the plant's wide-mouthed capsule. It can be found on gravelly banks or similar habitats and can be identified by the blue tinge to the overall green colour. The stem of this moss is wine red and it has rhizoids that keep the moss anchored to substrates. It is an acrocarpous moss that grows vertically with an archegonium borne at the top of each fertilized female gametophyte shoot which develops an erect sporophyte.
Warnstorfia exannulata is a leafy branching wetland moss in the genus Warnstorfia within the family Amblystegiaceae and class Bryopsida. This bryopsida moss is also known as ringless-hook moss or Warnstorfia moss. It is the most common species of the genus in wetland environments and can be difficult to distinguish from others within the genus. It grows in acidic soils like fens and bogs, or in freshwater pools and lakes.
Bartramia is a genus of mosses in the family Bartramiaceae. The genus was first formally described by Johann Hedwig in 1801. There are about 72 species, usually growing on soil, sometimes on rocks, in many habitats in many parts of the world, although tropical species are only found at high altitudes. Nine species occur in Australia but only three of these are endemic to that continent.
Bryum argenteum, the silvergreen bryum moss or silvery thread moss, is a species of moss in the family Bryaceae. It is one of the most common mosses of urban areas and can be easily recognized without a microscope.
Ptychostomum pseudotriquetrum, commonly known as marsh bryum, is a species of moss belonging to the family Bryaceae.
Polytrichastrum formosum, commonly known as the bank haircap moss, is a species of moss belonging to the family Polytrichaceae.
