Plagiomnium affine | |
Plagiomnium affine, the many-fruited thyme-moss, [1] 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. ('Plagio' = oblique, 'Mnium' = genus of thyme-moss)
Forming low lawns, stems are usually some 2 cm long, with densely packed leaves, though 10 cm long trailing infertile stems have only sparse leaves, smaller than those on fertile stems. Leaves strongly curled when dry, spreading plane when moist, the basal leaves broadly elliptic to rounded, those at the apex mucronate. Leaf edges of bases decurrent on stem, the upper leaves oblong to lingulate and constricted at base, toothed. [2] The leaf cells are arranged in diagonal rows and are easily discerned with a lens. [3]
Experiments to determine the efficacy of cryoprotectants show that the leaf covering is relatively impermeable to sugars, proline, and polyethylene glycols, but that dimethylsulfoxide is readily absorbed. Even so, it was found that frost hardiness is accompanied by a steep rise in cell sucrose concentration. [4] Cryoprotective compounds may play a major role in the frost tolerance of bryophytes. [5]
Helodium blandowii, also known as Blandow's helodium moss, Blandow's tamarisk-moss, Blandow's bogmoss, and Blandow's feathermoss, is a rare plant in the Western U.S., including Oregon and California. It occurs all around the northern hemisphere in higher latitudes, and in some places is not as rare as in the Western U.S.
Meesia triquetra, the three-ranked hump-moss, is a moss that occurs all around the northern hemisphere in higher latitudes.
Bryum warneum, known as sea bryum or Warne's threadmoss, is a protected moss found in sandy coastal areas in temperate regions of Europe and is also recorded to have been found in the Himalaya, the Altai Mountains and in Quebec, Canada.
Tayloria lingulata, commonly known as lingulate dung moss, tongue-leaved gland-moss, or marsh collar-moss, is a moss found in montane habitats in the Northern Hemisphere including Europe, Asia and North America.
Plagiomnium medium, commonly known as Alpine thyme-moss or intermediate plagiomnium moss, is a moss found in montane habitats in the Northern Hemisphere.
Funaria hygrometrica, the bonfire moss or common cord-moss, is a type of water moss which grows on shady, moist soil. It can also be found on moist walls and the crevices of rocks and places where recent fires have taken place. It has been reported to grow in Niagara Cave, an artificially illuminated cave devoid of natural light. Under such conditions, its growth form changes so that the internodes lengthen and the leaves become longer and narrower.
Dicranum scoparium, the broom forkmoss, is a species of dicranid moss, native to most of the northern hemisphere as well as Oceania. It usually forms tufts or mats on soil in dry to moist forested areas. As with many types of moss Broom moss grows in clumps with Broom mosses as well as other mosses. It can be distinguished by its leaves, which strongly curve to one side.
Bartramia pomiformis, the common apple-moss, is a species of moss in the Bartramiaceae family. It is typically green or glaucous in hue, although sometimes it can appear yellowish. The stems extend from a half cm to 8 cm, with narrowly lanceolate to linear-lanceolate leaves 4 - 9 mm long. The leaves have a nerve and are toothed. They are curled when dry but stick out when moist.
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.
Polytrichum juniperinum, commonly known as juniper haircap or juniper polytrichum moss, is an evergreen and perennial species of moss that is widely distributed, growing on every continent including Antarctica.
Tortula acaulon, formerly Phascum cuspidatum, the cuspidate earth-moss or toothed phascum moss, is a moss with 3 mm leaves which forms green patches. It is very common and has a number of varieties in a wide range of habitats. The variety piliferum occurs on sandy soils near the sea.
Mnium stellare, the starry thyme-moss or stellar calcareous moss, is a moss species in the genus Mnium.
Sphagnum cuspidatum, the feathery bogmoss, toothed sphagnum, or toothed peat moss, is a peat moss found commonly in Great Britain, Norway, Sweden, the eastern coast of the United States, and in Colombia.
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.
Rhizomnium punctatum, also called dotted thyme-moss, is a small species in the genus Rhizomnium.
Plagiomnium is a genus of mosses in the family Mniaceae. It was formerly a part of a more encompassing genus Mnium and in 1968 Finish bryologist Timo Juhani Koponen justified splitting the genus into a number of smaller genera.
Plagiomnium cuspidatum, also known as toothed or “baby-tooth” plagiomnium moss and woodsy thyme-moss, is a species of thyme-moss that originated in North America, but can now also be found throughout Middle America, Africa, Northern and Southern Asia, and Europe.
Polytrichastrum formosum, commonly known as the bank haircap moss, is a species of moss belonging to the family Polytrichaceae.
Mnium hornum, also known by the common names horn calcareous moss or swan's-neck thyme-moss, is a species of moss in the genus Mnium.
