Bryoria Alaskana
''Bryoria'' is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. The genus has a widespread distribution, especially in boreal and cool temperate areas. Taxonomy ''Bryoria'' was circumscribed in 1977 by lichenologists Irwin Brodo and David Hawksworth, with '' Bryoria trichodes'' as the type species. Description ''Bryoria'' species are fruticose, slender and hair-like, tending to grow hanging (pendent) or like a small bush. They range in colour from dark brown to pale greyish brown to grey in some species. Ascospores are colourless, ellipsoid, numbering eight per ascus. Other hair-like lichens that may be confused with ''Bryoria'' include dark brown species of ''Bryocaulon'', '' Nodobryoria'', ''Pseudephebe'', '' Alectoria'', or ''Cetraria''. Habitat and distribution Found almost exclusively on conifers, or on tundra soil, ''Bryoria'' collectively has a widespread distribution, especially in boreal and cool tem ...

Ascus
An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. '' Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. '' Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some '' Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bou ...

Bryoria Araucana
''Bryoria araucana'' is a species of lichen in the genus ''Bryoria''. Etymology ''Bryoria araucana'' was named after the IX Región de la Araucanía in Chile, which is the only known area for the species, as was the case in the name ''Araucaria araucana''. Description Thallus pendent to subpendent, 6–12 cm long; isotomic to anisotomic dichotomously branched, angles between dichotomies mainly obtuse, rarely acute; branches terete, even, main branches at base 0.2–0.4 mm diameter, tips to 0.1 mm diameter; terminal portions with few lateral branchlets acutely inserted. Surface dark grey to dark greyish brown, shiny, base ordinarily black; cortex prosoplectenchymatous. Soralia and isidia are lacking. The pseudocyphellae are inconspicuous, depressed, fusiform, concolorous to slightly darker than the thallus, sometimes faintly pruinose, straight or twisted, up to 1.5 mm long. The photobiont is trebouxioid. Apothecia and conidiomata are unknown. Chemistry. Inner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conifer
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and 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 ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime ada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetraria
''Cetraria'' is a genus of fruticose lichens that associate with green algae as photobionts. Most species are found at high latitudes, occurring on sand or heath. Species have a characteristic "strap-like" form, with spiny lobe edges. ''Cetraria islandica'', Iceland moss, is one of the few culinary lichens, ground and eaten by Northern Europeans in times of famine. Another species is used today as a "bulking" agent in garam masala of traditional Indian cuisine.
