Grimmia pulvinata, otherwise known as grey-cushioned grimmia [1] or pulvinate dry rock moss, [2] is a bryophyte moss common in temperate climates worldwide.
Grimmia pulvinata grows in small cushion-like shaped, around 1-2 centimeters tall. Its color ranges from a grey-green to an orange-yellow. [3] Its leaves are lanceolate, being broad and oval shaped at the base and very narrow toward the tip. [4] They may show a silvery hue near the tip in some specimens. Its capsules are oval shaped, and bend back into the leaves when the plant is dry, and stand out when it is moist. [3]
Grimmia pulvinata colonizes a variety of surfaces including rocks, concrete, and tree trunks. It is tolerant of a wide range of PH levels on surfaces, allowing it to live on many types of rock. [5]
However, it prefers surfaces such as old mortar and tree trunks. [6]
Grimmia pulvinata is the most common species in the genus Grimmia , with a nearly worldwide distribution. [5] It is particularly common in Britain [7] and the west coast of North America. [8] It primarily lives in temperate regions, from sea level to elevations up to 9800 feet. [5]
Grimmia pulvinata is a pioneer species, meaning it is among the first organisms to colonize habitat which has been disturbed by an event such as a forest fire. [4] In addition, its resistance to pollution allows it to colonize urban areas such as roofs, walls, and tarmac. [3]
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.
Schistostega pennata, also called goblin gold, Dragon's gold,luminous moss or luminescent moss, is a haplolepideous moss (Dicranidae) known for its glowing appearance in dark places. It is the only member of the family Schistostegaceae.
Meesia triquetra, the three-ranked hump-moss, is a moss that occurs all around the northern hemisphere in higher latitudes.
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.
Ceratodon purpureus is a dioicous moss with a color ranging from yellow-green to red. The height amounts to 3 centimeters. It is found worldwide, mainly in urban areas and next to roads on dry sand soils. It can grow in a very wide variety of habitats, from polluted highway shoulders and mine tailings to areas recently denuded by wildfire to the bright slopes of Antarctica. Its common names include redshank, purple forkmoss, ceratodon moss, fire moss, and purple horn toothed moss.
Hypnum cupressiforme, the cypress-leaved plaitmoss or hypnum moss, is a common and widespread species of moss belonging to the genus Hypnum. It is found in all continents except Antarctica and occurs in a wide variety of habitats and climatic zones. It typically grows on tree trunks, logs, walls, rocks and other surfaces. It prefers acidic environments and is fairly tolerant of pollution. It was formerly used as a filling for pillows and mattresses; the association with sleep is the origin of the genus name Hypnum.
Campylopus introflexus, also known as the heath star moss, is a species of moss. The first description of the species was made by Johannes Hedwig as Dicranum introflexum in 1801.
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.
Sphagnum capillifolium, the red bogmoss or small red peat moss, is a species of peat moss native to Canada, the northern United States, Greenland and Europe. Small red peat can be distinguished by its sweeping, outward-curving branches that resemble tresses.
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.
Calliergon cordifolium is a species of moss in the Calliergonaceae family, commonly known as the calliergon moss or heart-leaved spearmoss. The species is abundant in the right habitat, and grows in marshes and wet woodland, especially woodland of alder (Alnus) or willow (Salix), as well as around streams, ditches and pools. The species grows in tufts among other moss species. Calliergon cordifolium requires a wet environment to grow, and often grows completely submerged in water. It typically prefers lowland, but has been recorded as high as 910 metres (1,000 yd) above sea level in Inverness, Scotland. The species has a circumpolar Boreo-temperate distribution. It is found throughout Europe. It has been recorded in north and central Asia, as well as Turkey and Japan, throughout North America and in New Zealand.
Racomitrium lanuginosum is a widespread species of moss found in montane and arctic tundra across the Northern and Southern hemispheres. It grows as large mats on exposed rock and in boulder scree, particularly on acidic rocks. Its leaves have a characteristically decurrent and toothed hair-point, which gives rise to its regional common names woolly fringemoss, hoary rock-moss and woolly moss.
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.
Polytrichum strictum, commonly known as bog haircap moss or strict haircap, is an evergreen and perennial species of moss native to Sphagnum bogs and other moist habitats in temperate climates. It has a circumboreal distribution, and is also found in South America and Antarctica.
Andreaea rothii, or Roth's andreaea moss, is a species of moss in the family Andreaeaceae native to North America and parts of Europe. This plant was described in 1807 by Weber and Mohr.
Fissidens limbatus commonly known as Herzog’s pocket-moss, is a moss in the family Fissidentaceae. This species is found growing in high elevations in tropical america in addition to the USA, Mexico and Canada. Montagne first collected F. crispus in 1838.
Plagiomnium venustum, also known as magnificent leafy moss, is a species of moss belonging to the family Mniaceae. It is found mainly in western North America along the coastal region. This moss can be identified from other members of the Plagiomnium genus by dark coloured stomata guide cells and the absence of sterile stems. It is most commonly found growing as a mat on a variety of substrate, but mainly on humus and moist soil.
Orthotrichum lyellii, also known as Lyell's bristle moss, is a species of acrocarpous moss belonging to the family Orthotrichaceae. O. lyellii can be found throughout western North America and Europe. It is found most commonly growing epiphytically on a variety of trees, and less commonly on rocks or boulder substrates.
Andreaea rupestris is a species of moss in the class Andreaeopsida, are commonly referred to as the "lantern mosses" due to the appearance of their dehisced sporangia. It is typically found on smooth, acidic, exposed rock in the Northern hemisphere. It exhibits the common features of the genus Andreaea such as being acrocarpous, having dark pigmentation, lacking a seta, and bearing 4 lines of dehiscence in its mature sporangia, but can be further identified upon careful examination of its gametophytic leaves which have an ovate base to a more blunt apex compared to other similar species.
