Orthotrichum Lyellii

	Orthotrichum Lyellii ''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. Description ''Orthotrichum lyellii'' is generally described as forming green and yellow mats, with loose tufts reaching lengths of 3 to 4 cm forming mound-like structures. Its leaves are sharply pointed with a single costa and lanceolate linear leaf morphology, being very slender and reaching lengths of 2.5 to 6.5 mm. Tufts can reach lengths ranging from 10 to 13 cm, and often are found lying prostrate to the ground. The lamina cells of its leaves are papillose, and the entire leaf surface can often be found dusted with brown asexual propagules ( gemmae) which may help to distinguish it from similar species such as '' Orthotrichum papillosum.''

picture info	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 ...

	Gemma (botany) A gemma (plural ''gemmae'') is a single cell, or a mass of cells, or a modified bud of tissue, that detaches from the parent and develops into a new individual. This type of asexual reproduction is referred to as fragmentation. It is a means of asexual propagation in plants. These structures are commonly found in fungi, algae, liverworts and mosses, but also in some flowering plants such as pygmy sundews and some species of butterworts. Vascular plants have many other methods of asexual reproduction including bulbils and turions. In mosses and liverworts The production of gemmae is a widespread means of asexual reproduction in both liverworts and mosses. In liverworts such as ''Marchantia'', the flattened plant body or thallus is a haploid gametophyte A gametophyte () is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Bryopsida The Bryopsida constitute the largest class of mosses, containing 95% of all moss species. It consists of approximately 11,500 species, common throughout the whole world. The group is distinguished by having spore capsules with teeth that are ''arthrodontous''; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule.Buck, William R. & Bernard Goffinet. (2000) "Morphology and classification of mosses", pages 71-123 ''in'' A. Jonathan Shaw & Bernard Goffinet (Eds.), ''Bryophyte Biology''. (Cambridge: Cambridge University Press). Consequently, mosses in the Class Bryopsida are commonly known as the “joint-toothed” or “arthrodontous” mosses. These teeth are exposed when the covering operculum falls off. In other groups of mosses, the capsule is either ''nematodontous'' with an attached operculum, or else splits open without operculum or teeth. Morphological groups The Bryopsida can be simplified into three groups: the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
