Lichinodium
''Lichinodium'' is a genus of filamentous lichens. It is the only genus in the family Lichinodiaceae, itself the only member of the order Lichinodiales. ''Lichinodium'' has four species. Previously considered part of the class Lichinomycetes, molecular phylogenetic analysis revealed that ''Lichinodium'' represents a unique lineage in the Leotiomycetes—the first known group of lichen-forming fungi in this class. Taxonomy The genus ''Lichinodium'' is typified by ''Lichinodium sirosiphoideum'', first described in 1875 by William Nylander. Aino Henssen added three species to the genus about a century later. ''Lichinodium'' used to be classified in the Lichinomycetes, but molecular phylogenetic analysis published in 2018 showed that the genus was incorrectly classified there, and that instead it represents a new lichen-forming lineage in the superclass Sordariomyceta (containing the (Leotiomycetes, Laboulbeniomycetes, and the Sordariomycetes), a major fungal group that was not pre ...

Lichinodium Canadense
''Lichinodium canadense'' is a species of minute fruticose (bushy) cyanolichen in the family Lichinodiaceae. It is found in British Columbia, Canada, where it grows on conifer bark. Taxonomy ''Lichinodium canadense'' was formally described as a new species in 1968 by Norwegian lichenologist Aino Henssen. The type specimen was collected in the Fraser River basin along Highway 1; here, in a mixed forest along a riverbank, the lichen was found growing on the bark of western redcedar (''Thuja plicata''), along with a then-undescribed species of ''Parmeliella''. The specific epithet ''canadense'' refers to the country in which it was first found. The species has also been recorded from the Incomappleux River valley in southeastern British Columbia. Description ''Lichinodium canadense'' has a brownish to blackish coloured, gelatinous thallus that occurs as single rosettes with a diameter of . The individual lobes comprising the thallus are 0.4–0.8 mm long and 0.04–0.06 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leotiomycetes
The Leotiomycetes are a class of ascomycete fungi. Many of them cause serious plant diseases. Systematics The class Leotiomycetes contains numerous species with an anamorph placed within the ''fungi imperfecti'' (deuteromycota), that have only recently found their place in the phylogenetic system. The older classifications placed Leotiomycetes into the Discomycetes clade ( inoperculate Discomycetes). Molecular studies have recently shed some new light to the still obscure systematics. Most scholars consider Leotiomycetes a sister taxon to Sordariomycetes in the phylogenetic tree of Pezizomycotina. Its division into subclasses have received strong support by the molecular data, but the overall monophyly of Leotiomycetes is dubious. The order Lichinodiales and family Lichinodiaceae, newly circumscribed in 2019 to contain the genus cyanolichen genus '' Lichinodium'', is the first known group of lichen-forming fungi in the Leotiomycetes.

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

Nostocaceae
The Nostocaceae are a family of cyanobacteria that forms filament-shaped colonies enclosed in mucus or a gelatinous sheath. Some genera in this family are found primarily in fresh water (such as ''Nostoc''), while others are found primarily in salt water (such as '' Nodularia''). Other genera (e.g. ''Anabaena'') may be found in both fresh and salt water. Most benthic algae of the order Nostocales belong to this family. Like other cyanobacteria, these bacteria sometimes contain photosynthetic pigments in their cytoplasm to perform photosynthesis. The particular pigments they contain gives the cells a bluish-green color. Species of the Nostocaceae are particularly known for their nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern, cycads, and hornworts. The cyanobacteria provide nitrogen to their hosts. Certain species of ''Anabaena'' have been used on rice paddy fields. Mosquito ferns carrying the cyanobacteria grow ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission Electron Microscopy
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device. Transmission electron microscopes are capable of imaging at a significantly higher resolution than light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope. Transmission electron microscopy is a major analytical method i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conidiomata
Conidiomata (singular: Conidioma) are blister-like fruiting structures produced by a specific type of fungus called a coelomycete. They are formed as a means of dispersing asexual spores call conidia, which they accomplish by creating the blister-like formations which then rupture to release the contained spores. Structure Conidiomata mainly consist of a mass of densely packed hypha which develops below the surface of the host cuticle, and the fungus may or may not use some of the host’s own tissue to construct the structure. Development of these structures can either occur just below the cuticle or below the epidermal layer of the tissue. Formation on the differing levels is dependent upon the type of conidiomata being formed. Five types of conidioma have been found and are classified as acervuli, pycnidia, sporodochia, synnemata and corenima. Types Acervuli Acervuli is one of the two major groups of conidiomata (the other being pycnidia). Conidiomata of this type form ju ...
