Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidiomycota
Basidiomycota () is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. More specifically, Basidiomycota includes these groups: mushrooms, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars, smuts, bunts, rusts, mirror yeasts, and ''Cryptococcus'', the human pathogenic yeast. Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores. However, some Basidiomycota are obligate asexual reproducers. Basidiomycota that reproduce asexually (discussed below) can typically be recognized as members of this division by gross similarity to others, by the form ...

Agaricomycetes
The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes (alternatively called holobasidiomycetes) by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as ''Auricularia'', are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales ...

Polyporales
The Polyporales are an order of about 1800 species of fungi in the division Basidiomycota. The order includes some (but not all) polypores as well as many corticioid fungi and a few agarics (mainly in the genus ''Lentinus''). Many species within the order are saprotrophic, most of them wood-rotters. Some genera, such as ''Ganoderma'' and ''Fomes'', contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially cultivated and marketed for use as food items or in traditional Chinese medicine. Taxonomy History The order was originally proposed in 1926 by Swiss mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota producing basidiocarps (fruit bodies) showing a gymnocapous mode of development (forming the spore-bearing surface ext ...

Meruliaceae
The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. , Index Fungorum accepts 645 species in the family. Taxonomy The family was formally circumscribed by English mycologist Carleton Rea in 1922, with ''Merulius'' as the type genus. He also included the genera ''Phlebia'', '' Coniophora'' (now placed in the Coniophoraceae), and ''Coniophorella'' (now considered a synonym of ''Coniophora''). His description of the Meruliaceae was as follows: "Hymenium spread over veins, anastomosing pores, or quite smooth; ''edge of veins or pores fertile.''" Several genera formerly classified in the Meruliaceae were moved to the family Steccherinaceae based on molecular evidence. Description Meruliaceae species are crust-like or polyporoid, and often have a waxy appearance when dry. Their hyphal systems are monomitic (containing only tightly arranged generative hyphae), and these hyphae have clamp connec ...

Irpex
''Irpex'' is a genus of corticioid fungi in the order Polyporales. Species produce fruit bodies that grow as a crust on the surface of dead hardwoods. The crust features an irpicioid spore-bearing surface (for which the genus is named), meaning it has irregular and flattened teeth. ''Irpex'' is distinguished from the similar genera '' Junghuhnia'' and ''Steccherinum'' by the simple septa found in the generative hyphae. Classification Although ''Irpex'' has been classified in the family Steccherinaceae, or the Meruliaceae, phylogenetic analysis has shown that its type species, '' Irpex lacteus'', is more closely related to ''Byssomerulius'' in the Phanerochaetaceae. Justo and colleagues support a 2003 proposal that places ''Irpex'' as the type genus of family Irpicaceae The Irpicaceae are a family of mostly polypores and crust fungi in the order Polyporales. Taxonomy The family was circumscribed in 2003 by mycologists Viacheslav Spirin and Ivan Zmitrovich. The type genus is '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Petch
Thomas Petch (born Hornsea, Yorkshire, 11 March 1870; died King's Lynn, Norfolk, 24 December 1948) was a prolific English mycologist and plant pathologist best remembered for his work on the interaction between fungi and insects. Biography Petch was educated at the choir school of Holy Trinity at Hull, and taught at the King's Lynn Grammar School and Leyton Technical Institute while preparing for external degrees at the University of London. Petch had an early interest in natural history, but Charles Plowright, a doctor and mycologist in King's Lynn, encouraged him to study fungi. Through a friendship with George Massee of the Royal Botanical Gardens Petch was appointed Mycologist to the Government of Ceylon in 1905. He returned to England briefly to marry Edith Mary Plowright (b. 1875), Charles' daughter, in 1908. Petch held this position until 1924. After a leave to visit England, he returned to Ceylon as the founding director of the Tea Research Institute. In 1928 he reti ...

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 populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
