Karl Friedrich Wilhelm Wallroth
Karl Friedrich Wilhelm Wallroth (13 March 1792 in Breitenstein, Saxony-Anhalt – 22 March 1857 in Nordhausen, Thuringia, Nordhausen) was a German botanist. His name is abbreviated Wallr. as a taxon authority. He attended classes in medicine and botany at the University of Halle, afterwards continuing his studies in Göttingen, where he was a pupil of botanist Heinrich Schrader (botanist), Heinrich Adolf Schrader (1767-1836). In 1816 he obtained his medical doctorate at the University of Göttingen. In 1822 he was appointed district physician to the city of Nordhausen, Thuringia, Nordhausen, where along with his duties as a doctor, he performed botanical research. Among his writings were a treatise on cryptogams native to Germany, ''Flora Cryptogamica Germaniae'' (1831–33), and a study on the biology of lichens, titled ''Naturgeschichte der Flechten'' (1825 and 1827). Wallroth is credited for introducing the terms "" and "" to explain two distinct forms of lichen thallus, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chrysomyxa
''Chrysomyxa'' is a genus of rust fungi in the family Coleosporiaceae. The genus, widespread in the Northern Hemisphere, contains about 23 species. Rust fungi in the genus ''Chrysomyxa'' occur in boreal forests of the northern hemisphere on Pinaceae, (mostly ''Picea''), and most species alternate to angiosperm hosts in the Ericaceae The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it th ....Crane, P.E. 2001.

Spruce
A spruce is a tree of the genus ''Picea'' (), a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Earth. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine family by their needles (leaves), which are four-sided and attached singly to small persistent peg-like structures (pulvini or sterigmata) on the branches, and by their cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species, such as the eastern spruce budwo ...

Angelfire
Angelfire is an Internet service that offers website services. It is owned by Lycos, which also owns Tripod.com. Angelfire operates separately from Tripod.com and includes features such as blog building and a photo gallery builder. Free webpages are no longer available to new registrants and have been replaced by paid services. History Angelfire was founded in 1996 and was originally a combination Web site building and medical transcription service. Eventually the site dropped the transcription service and focused solely on website hosting, offering only paid memberships. The site was bought by Mountain View, California–based WhoWhere on October 20, 1997, which, in turn, was subsequently purchased by the search engine company Lycos on August 11, 1998 for US$133 million. Since Lycos already offered free website hosting with advertising through its acquisition of Tripod.com, Angelfire's offering was modified to also have parity with Tripod, including the addition of an increas ...

Pustule
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions result ...

Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from el, ὑάλινος, translit=hyálinos, lit=transparent, and el, ὕαλος, translit=hýalos, lit=crystal, glass, label=none. Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology, ''hyaline'' denotes a colorless, transparent substance, such as unpigmented fins of fishes or clear insect wings. Resh, Vincent H. and R. T.

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular sep ...

Teliospore
Teliospore (sometimes called teleutospore) is the thick-walled resting spore of some fungi ( rusts and smuts), from which the basidium arises. Development They develop in '' telia'' (sing. ''telium'' or ''teliosorus''). The telial host is the primary host in heteroecious rusts. The aecial host is the alternate host (look for pycnia and aecia). These terms apply when two hosts are required by a heteroecious rust fungus to complete its life cycle. Morphology Teliospores consist of one, two or more dikaryote cells. Teliospores are often dark-coloured and thick-walled, especially in species where they overwinter (acting as chlamydospores). Two-celled teliospores formerly defined the genus ''Puccinia''. Here the wall is particularly thick at the tip of the terminal cell which extends into a beak in some species. Teliospores consist of dikaryote cells. As the teliospore cells germinate, the nuclei undergo karyogamy and thereafter meiosis, giving rise to a four-celled basidiu ...

Magical creatures are an aspect of the fictional Wizarding World contained in the ''Harry Potter'' series and connected media, all created by British author J. K. Rowling. Throughout the seven main books of the series, Harry Potter (character), Harry and his friends encounter many of these creatures on their adventures in Hogwarts, the Forbidden Forest (Harry Potter), Forbidden Forest, or other locations throughout the Wizarding World. In addition, students learn to take care of creatures such as hippogriffs and unicorns in the Care of Magical Creatures class at Hogwarts. Rowling has also written ''Fantastic Beasts and Where to Find Them'', a guide to the magical beasts found in the series, and based on the fictional textbook of the same name written by Newt Scamander and used by students at Hogwarts. Many of these creatures are derived primarily from Greek mythology and other folklore, namely English folklore, British and Scandinavian folklore. Many of the legends surrounding th ...
