Mordecai Cubitt Cooke
Mordecai Cubitt Cooke (12 July 1825, in Horning, Norfolk – 12 November 1914, in Southsea, Hampshire) was an English botanist and mycologist who was, at various points, a London schoolteacher, a Kew mycologist, curator at the India Museum, journalist and author, .Mary P. English (1987), ''Mordecai Cubitt Cooke: Victorian naturalist, mycologist, teacher & eccentric''. Biopress, Bristol, ] Cooke was the elder brother of the art-education reformer Ebenezer Cooke (art education reformer), Ebenezer Cooke (1837–1913) and father of the book illustrator and watercolour painter William Cubitt Cooke (1866–1951). Life Cooke, from a mercantile family in Horning, Norfolk, was apprenticed to a fabric merchant before becoming a clerk in a law firm, but his chief interest was botany. He founded the ''Society of Amateur Botanists'' in 1862 while teaching natural history at Holy Trinity National School, Lambeth, and working as a curator at the India Museum at India Office from 1860. In 1879, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leif Ryvarden
Leif Randulff Ryvarden (born 9 August 1935) is a Norwegian mycologist. Early life and education Leif Ryvarden was born in Bergen as a son of Einar Norberg Johansen (1900–1959) and Hjørdis Randulff (1912–1975). He finished his secondary education at Berg in 1954 and took basic military education from 1957 to 1958 and in 1956 he changed his last name from Johansen to Ryvarden. He studied chemistry at the Norwegian Institute of Technology. In 1961 he ran for election as chairman of Student Society in Trondheim, albeit unsuccessfully. In 1963, he graduated with the siv.ing. degree , and later majored in botany at the University of Oslo, taking a cand.real. degree. He also studied in London from 1971 to 1972, a stay that sparked his interest in mycology. Academic career Ryvarden conducted field work in about eighty countries, mostly in a tropical environment.

Curtis Gates Lloyd
Curtis Gates Lloyd (July 17, 1859 – November 11, 1926) was an American mycologist known for both his research on the gasteroid and polypore fungi, as well as his controversial views on naming conventions in taxonomy. He had a herbarium with about 60,000 fungal specimens, and described over a thousand new species of fungi. Along with his two brothers John Uri Lloyd and Nelson Ashley Lloyd, he founded the Lloyd Library and Museum in Cincinnati. Early life Born on July 17, 1859 in Florence, Kentucky, Curtis Gates Lloyd was the third son of Nelson Marvin and Sophia Webster Lloyd. He and his family moved to Crittenden, Kentucky, in 1867, where Lloyd lived until he was 18. He moved to Cincinnati and was employed as an apprentice in Johnson's pharmacy. This was where he met Dr. John King, physician and editor of the ''American Dispensatory''; the close friendship they formed helped to fuel Lloyd's interest in botany. Lloyd earned his pharmacy certificate while working at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypore
Polypores are a group of fungi that form large fruiting bodies with pores or tubes on the underside (see Delimitation for exceptions). They are a morphological group of basidiomycetes-like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi or shelf fungi, and they characteristically produce woody, shelf- or bracket-shaped or occasionally circular fruiting bodies that are called conks. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and the related corticioid fungi are the most important agents of wood decay, playing a very significant role in nutrient cycling and aiding carbon dioxide absorption by forest ecosystems. Over one thousand polypore species have been described to science, but a large part of the diversity is still unknown even in relatively well-studied temperate areas. Polypores are much more ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rigidoporus
''Rigidoporus'' is a genus of fungi in the family Meripilaceae. Many of the species in this genus are plant pathogens. The widespread genus, which contains about forty species, was originally circumscribed by American mycologist William Alphonso Murrill in 1905. The generic name combines the Latin word ''rigidus'' ("rigid") with the Ancient Greek word ("pore").

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood-decay Fungus
A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as '' Armillaria'' (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil. Wood-decay fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.Viitanen, T. et al. (2010). Towards modelling of decay risk of wooden materials. European Journal of Wood and Wood Products 68:303-313. Wood-decay fungi can be classified according to the type of decay that they cause. The best-known types are brown rot, soft rot, and wh ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of Flowering plant, flowering trees, shrubs or Mallee (habit), mallees in the Myrtaceae, myrtle Family (biology), family, Myrtaceae. Along with several other genera in the Tribe (biology), tribe Eucalypteae, including ''Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil Gland (botany), glands, and sepals and petals that are fused to form a "cap" or Operculum (botany), operculum over the stamens. The fruit is a woody Capsule (botany), capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are Indigenous (ecology), native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which sur ...

Fungi Described In 1883
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Of Australia
The Fungi of Australia form an enormous and phenomenally diverse group, a huge range of freshwater, marine and terrestrial habitats with many ecological roles, for example as saprobes, parasites and mutualistic symbionts of algae, animals and plants, and as agents of biodeterioration. Where plants produce, and animals consume, the fungi recycle, and as such they ensure the sustainability of ecosystems. Knowledge about the fungi of Australia is meagre. Little is known about aboriginal cultural traditions involving fungi, or about aboriginal use of fungi apart from a few species such as Blackfellow's bread ('' Laccocephalum mylittae''). Humans who came to Australia over the past couple of centuries brought no strong fungal cultural traditions of their own. Fungi have also been largely overlooked in the scientific exploration of Australia. Since 1788, research on Australian fungi, initially by botanists and later by mycologists, has been spasmodic and intermittent. At governmental l ...
