Boletus Russelli
''Aureoboletus russellii'', commonly known as the Russell's bolete, or jagged-stemmed bolete, is a species of bolete fungus in the family Boletaceae. An edible species, it is found in Asia and eastern North America, where it grows in a mycorrhizal association with oak, hemlock, and pine trees. Fruit bodies of the fungus are characterized by their coarsely shaggy stem. The yellow-brown to reddish-brown caps are initially velvety, but become cracked into patches with age. Taxonomy Originally named ''Boletus russellii'' by Charles Christopher Frost in 1878 from collections made in New England, the species was transferred to ''Boletellus'' by Edouard-Jean Gilbert in 1931. It was then transferred to '' Aureoboletus'' by Gang Wu and Zhu L. Yang in 2016. The specific epithet ''russellii'' honors American botanist and Unitarian minister John Lewis Russell, the first collector of the species. Common names given to the mushroom include shagnet, jagged-stem bolete, and Russell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Christopher Frost
Charles Christopher Frost (November 11, 1805 – March 16, 1880) was an American mycologist. He described several species of fungi from the New England area of the United States. In one paper, Frost described 22 new species of boletes, and he was later credited with the discovery of three additional species. His personal herbarium of specimens were given to the University of Vermont in 1902. Portions of his collection today are distributed between the Farlow Herbarium at Harvard University, the New York State Museum, the Bell Museum of Natural History, and the Buffalo Museum of Science. Early life Frost was born in Brattleboro, Vermont, on November 11, 1805. His parents were shoemaker James Frost and Elizabeth Stewart, daughter of an officer in the American Revolution. When he was fifteen, Frost left school after being hit with a ruler by a teacher, and assisted his father with his business. Although Frost had developed a prior interest in the natural sciences, his interest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Assembly Of Unitarian And Free Christian Churches
The General Assembly of Unitarian and Free Christian Churches (GAUFCC or colloquially British Unitarians) is the umbrella organisation for Unitarian, Free Christians, and other liberal religious congregations in the United Kingdom and Ireland. It was formed in 1928, with denominational roots going back to the Great Ejection of 1662. Its headquarters is Essex Hall in central London, on the site of the first avowedly Unitarian chapel in England, set up in 1774. The GAUFCC brought together various strands and traditions besides Unitarianism, including English Presbyterianism, General Baptist, Methodism, Liberal Christianity, Christian Universalism, Religious Humanism, and Unitarian Universalism. Unitarians are now an open-faith community celebrating diverse beliefs; some of its members would describe themselves as Buddhists, Pagans, or Jewish, while many others are humanists, agnostics, or atheists. History Early Modern Britain Christopher Hill states that ideas such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aureoboletus Betula
''Aureoboletus betula'' is a species of mushroom producing fungus in the family Boletaceae. It is commonly known as the Shaggy Stalked Bolete. Taxonomy It was first described in 1822 by the German-American mycologist Lewis David de Schweinitz and classified as ''Boletus betula.'' It has been reclassified many times over the years and is still sometimes referred to by the 2004 classification ''Heimioporus betula'' as given to it by the Austrian mycologist Egon Horak. In 2020 it was reclassified as ''Aureoboletus betula'' by the mycologists Michael Kuo and Beatriz Ortiz-Santana. Description ''Aureoboletus betula'' features finely pitted spores. It is found under oaks, or in mixed woods of pine and oak, primarily in the southern Appalachians. This bolete has a stem that is deeply, coarsely reticulate and, when the mushroom is in the "button" stage, often as wide as, or even wider than, the cap. With development the stem stretches out dramatically, becoming notably long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a 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 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 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 . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it ...

Mushroom Hunting
Mushroom hunting, mushrooming, mushroom picking, mushroom foraging, and similar terms describe the activity of gathering mushrooms in the wild, typically for culinary use. This practice is popular throughout most of Europe, Australia, Japan, Korea, parts of the Middle East, and the Indian subcontinent, as well as the temperate climate, temperate regions of Canada and the United States. Identifying mushrooms Morphological characteristics of the caps of mushroom, such as those illustrated in the above chart, are essential for correct visual mushroom identification. Numerous field guides on mushrooms are available and recommended to help distinguish safe, edible mushrooms from the many poisonous or inedible species. A spore print is a mushroom identification technique commonly used by mycologists and mushroom hunters to help identify the genus of a specimen and differentiate between similar looking species. Knowing where and when to search for mushrooms is an important iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guide A field guide is a book designed to help the reader identify wildlife (flora or fauna) or other objects of natural occurrence (e.g. rocks and minerals). It is generally designed to be brought into the "field" or local area where such objects exi ...s and on identification websites. Ring descriptions The way in which the structure and appea ...

Partial Veil
In mycology, a partial veil (also called an inner veil, to differentiate it from the "outer", or universal veil) is a temporary structure of tissue found on the fruiting bodies of some basidiomycete fungi, typically agarics. Its role is to isolate and protect the developing spore-producing surface, represented by gills or tubes, found on the lower surface of the cap. A partial veil, in contrast to a universal veil, extends from the stem surface to the cap edge. The partial veil later disintegrates, once the fruiting body has matured and the spores are ready for dispersal. It might then give rise to a stem ring, or fragments attached to the stem or cap edge. In some mushrooms, both a partial veil and a universal veil may be present. Structure In the immature fruit bodies of some basidiomycete fungi, the partial veil extends from the stem surface to the cap margin and shields the gills during development, and later breaks to expose the mature gills.
