Trichia Decipiens
''Trichia decipiens'' is a worldwide widespread slime mould species from the order Trichiida. Characteristics The plasmodium is white, becoming pink to red at maturity. The small- to large-group-forming fruiting bodies are shiny olive to yellow-olive or brown, and bear mainly stalked, rarely sessile sporangia. These are conical to peak-shaped and are up to 3 mm high and 0.6 to 0.8 (rarely up to 1.3) mm wide. The shiny, membraneous hypothallus is wide, and pale to brown in colour. The cylindrical stem is wrinkled, dark brown at the base and becoming gradually lighter toward the top, and is filled with up to 1 mm-long, spore-like bodies. The solid or membranous peridium is yellow, often transparent on thin areas, thickened and deeper beneath, surviving as an initially shallow calyculus. The capillitium from the mass is olive to olive-yellow and is composed of non-overgrown, simple or branched, deeply olive-yellow, 5 to 6 µm thick elaters, which stand in reli ...

Christiaan Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to dona ...

Capillitium
Capillitium (pl. capillitia) is a mass of sterile fibers within a fruit body interspersed among spores. It is found in Mycetozoa (slime molds) and gasteroid fungi of the fungal subdivision Agaricomycotina The subdivision Agaricomycotina, also known as the hymenomycetes, is one of three taxa of the fungal division Basidiomycota (fungi bearing spores on basidia). The Agaricomycotina contain some 20,000 species, and about 98% of these are in the cla .... In the fungi, the form of the capillitia, including shape, size, branching patterns, presence or absence of slits or pores, thickness of the walls, and color, are features that can be used to identify certain species or genera.

Chemnitz
Chemnitz (; from 1953 to 1990: Karl-Marx-Stadt , ) is the third-largest city in the German state of Saxony after Leipzig and Dresden. It is the 28th largest city of Germany as well as the fourth largest city in the area of former East Germany after (East) Berlin, Leipzig and Dresden. The city is part of the Central German Metropolitan Region, and lies in the middle of a string of cities sitting in the densely populated northern foreland of the Elster and Ore Mountains, stretching from Plauen in the southwest via Zwickau, Chemnitz and Freiberg to Dresden in the northeast. Located in the Ore Mountain Basin, the city is surrounded by the Ore Mountains to the south and the Central Saxon Hill Country to the north. The city stands on the Chemnitz River (progression: ), which is formed through the confluence of the rivers Zwönitz and Würschnitz in the borough of Altchemnitz. The name of the city as well as the names of the rivers are of Slavic origin. Chemnitz is the third larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stemonitis Typhina
''Stemonitis'' is a distinctive genus of slime moulds found throughout the world (except Antarctica). They are characterised by the tall brown sporangia, supported on slender stalks, which grow in clusters on rotting wood. The genus was first described by German botanist Johann Gottlieb Gleditsch in 1753. A 2014 estimate suggests that there are 18 species in the genus. Identification within the genus is difficult, and can only be performed with confidence using a microscope or by DNA sequencing. A fossil specimen (in Burmese amber) is known from the mid-Cretaceous (99 ma). Species The following species are accepted by ''Species Fungorum'': *'' Stemonitis axifera'' (Bull.) T.Macbr.

Lycogala Epidendrum
''Lycogala epidendrum'', commonly known as wolf's milk or groening's slime, is a cosmopolitan species of myxogastrid amoeba which is often mistaken for a fungus. The aethalia, or fruiting bodies, occur either scattered or in groups on damp rotten wood, especially on large logs, from June to November. These aethalia are small, pink to brown cushion-like blobs. They may ooze a pink "paste" if the outer wall is broken before maturity. When mature, the colour tends to become more brownish. When not fruiting, single celled individuals move about as very small, red amoeba-like organisms called plasmodia, masses of protoplasm that engulf bacteria, as well as fungal and plant spores, protozoa, and particles of non-living organic matter through phagocytosis (see slime mould for more information). Description During the plasmodial stage, individuals are reddish in colour, but these are almost never seen. When conditions change, the individuals aggregate by means of chemical signalling ...

Cribraria
''Cribraria'' is a genus of slime molds from the group of Myxogastria. It comprises about 30 species, some of which are extremely difficult to distinguish. Features The fruiting bodies are usually pedunculated sporangia, a calyculus may be present or absent. The delicate peridium The peridium is the protective layer that encloses a mass of spores in fungi. This outer covering is a distinctive feature of gasteroid fungi.

Broadleaf Tree
A broad-leaved, broad-leaf, or broadleaf tree is any tree within the diverse botanical group of angiosperms that has flat leaves and produces seeds inside of fruits. It is one of two general types of trees, the other being a conifer, a tree with needle-like or scale-like leaves and seeds borne in woody cones. Broad-leaved trees are sometimes known as hardwoods. Most deciduous trees are broad-leavedLee, S. and A. RafloTrees and Water. Virginia Water Resources Research Center. Virginia Tech. but some are coniferous, like larches.

Conifers
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 adaptations. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elater
An elater is a cell (or structure attached to a cell) that is hygroscopic, and therefore will change shape in response to changes in moisture in the environment. Elaters come in a variety of forms, but are always associated with plant spores. In many plants that do not have seeds, they function in dispersing the spores to a new location. Mosses do not have elaters, but peristomes which change shape with changes in humidity or moisture to allow for a gradual release of spores. Horsetail elaters In the horsetails, elaters are four ribbon-like appendages attached to the spores. These appendages develop from an outer spiral layer of the spore wall. At maturity, the four strips peel away from the inner wall, except at a single point on the spore where all four strips are attached. Under moist conditions, the elaters curl tightly around the spore. The wet spores tend to stick to each other and to nearby surfaces because of surface tension. When conditions are dry, the spores no long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
