Bovista Dermoxantha
''Bovista dermoxantha'' is a small, white, nearly round puffball, recognized when young by a cottony-felty outer surface that becomes inconspicuously warted, eventually leaving fine, pallid, scales on an ochre to brown endoperidium. ''Bovista plumbea'' is similar, but has a smoother surface when young, and lacks a basal mycelial cord. In age it is distinguished by a dull greyish endoperidium. Large specimens of ''Bovista dermoxantha'' may also be mistaken for '' Bovista pila''. Both have a mycelial cord attachment to the substrate, but ''Bovista pila'' differs in releasing spores through tears or splits in the endoperidium rather than by an apical pore. Description The fruiting body of the sporocarp is 1.5-3.0 (4.0) cm broad, subglobose, and attached to the substrate by a white mycelial cord. The exoperidium, which is white, felty, and shrivels in age, leaving buff to light-brown, grows up to 1.0 mm thick. There are furfuraceous scales or low warts on the endoperidium, w ...

Christian Hendrik Persoon
Christiaan Hendrik Persoon (31 December 1761 – 16 November 1836) was a Cape Colony mycologist who is recognized as one of the founders of mycology, mycological Taxonomy (biology), taxonomy. Early life Persoon was born in Cape Colony at the Cape of Good Hope, the third child of an immigrant Pomeranian father, Christiaan Daniel Persoon, and Netherlands, Dutch mother, Wilhelmina Elizabeth Groenwald. His mother died soon after he was born. In 1775, at the age of thirteen, he was sent to Europe for his education. His father died a year later in 1776. Education Initially a student of theology at University of Halle-Wittenberg, Halle, Persoon switched his studies to medicine, which he pursued in Leiden and then Göttingen. He received a doctorate from the German National Academy of Sciences Leopoldina, Deutsche Akademie der Naturforscher in Erlangen 1799. Later years He moved to Paris by 1803, where he spent the rest of his life, renting the upper floor of a house in a poor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taste
The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste. Taste is the perception stimulated when a substance in the mouth biochemistry, reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with olfaction, the sense of smell and trigeminal nerve stimulation (registering texture, pain, and temperature), determines Flavoring, flavors of food and other substances. Humans have taste receptors on taste buds and other areas, including the upper surface of the tongue and the epiglottis. The gustatory cortex is responsible for the perception of taste. The tongue is covered with thousands of small bumps called lingual papillae, papillae, which are visible to the naked eye. Within each papilla are hundreds of taste buds. The exceptions to this is the filiform papillae that do not contain taste buds. There are between 2000 and 5000Boron, W.F., E.L. Boulpaep. 200 ...

Insects
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the b ...

Conocybe Lactea
''Conocybe apala'' is a basidiomycete fungus and a member of the genus ''Conocybe''. The species has been taxonomically reclassified a number of times. Until recently, it was also commonly called ''Conocybe lactea'' or ''Conocybe albipes'' and is Colloquialism, colloquially known as the white dunce cap or the milky conecap. It is a fairly common fungus, both in North America and Europe, found growing among short green grass. Taxonomy The basionym ''Agaricus apalus'' was described by the Swedish mycologist Elias Magnus Fries in 1818. It was placed in the genus ''Bolbitius'' as ''B. albipes'' by G.H. Otth (1871), then reclassified as ''Pluteolus apalus'' by the French mycologist Lucien Quélet in 1886. This was reclassified as ''Galera hapala'' (or ''Galera apala'') in 1887 by Pier Andrea Saccardo, then as ''Bolbitius apalus'' in 1891 by Julien Noël Costantin and Léon Jean Marie Dufour and finally as ''Derminus apalus'' in 1898 by Paul Christoph Hennings.

Summer
Summer or summertime is the hottest and brightest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, daylight hours are the longest and darkness hours are the shortest, with day length decreasing as the season progresses after the solstice. The earliest sunrises and latest sunsets also occur near the date of the solstice. The date of the beginning of summer varies according to definition, climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Etymology The modern English ''summer'' derives from the Middle English ''somer'', via the Old English ''sumor''. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with 21 June or 21 December.

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperature
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measurement, measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), with the third being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible ...

Bovista
''Bovista'' is a genus of fungi commonly known as the true puffballs. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the species of ''Bovista'' are now placed in the family Agaricaceae of the order Agaricales. ''Bovista'' species have a collectively widespread distribution, and are found largely in temperate regions of the world. Various species have historically been used in homeopathic preparations. Description Fruit bodies are oval to spherical to pear-shaped, and typically in diameter with a white or light-colored thin and fragile exoperidium (outer layer of the peridium). Depending on the species, the exoperidium in a young specimen may be smooth, granular, or finely echinulate. This exoperidium sloughs off at maturity to expose a smooth endoperidium with a single apical pore (ostiole). The fruit bodies may be attached to the ground by fine rhiz ...

Capillitium
Capillitium (pl. capillitia) is a mass of sterile fibers within a fruit body interspersed among spores. It is found in Mycetozoa Mycetozoa is a polyphyletic grouping of slime molds. It was originally thought to be a monophyletic clade, but in 2010 it was discovered that protostelia are a polyphyletic group within Conosa. Classification It can be divided into dictyoste ... (slime molds) and gasteroid fungi of the fungal subdivision Agaricomycotina. 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.

Micrometre
The micrometre (English in the Commonwealth of Nations, Commonwealth English as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI Unit, SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cell (biology), cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of str ...
