Botryobasidiaceae
The Botryobasidiaceae are a family of fungi in the order Cantharellales. The family contains a group of corticioid fungi that form thin, web-like basidiocarps. Some species form asexual anamorphs producing chlamydospores. All are believed to be wood-rotting or litter-rotting saprotrophs. None is known to be of any economic importance. Taxonomy History The name Botryobasidioideae was first introduced as a subfamily of the Corticiaceae in 1958 by Swedish mycologist John Eriksson, but was not fully described and validly published until taken up by Estonian mycologist Erast Parmasto in 1968. Parmasto placed the genera '' Botryobasidium'' (together with the anamorphic genus ''Oidium'') and '' Uthatobasidium'' within the subfamily, noting that they shared certain "primitive" characters linking them to the Ceratobasidiaceae and Tulasnellaceae. In 1982 Jülich raised the subfamily to the rank of family, as the Botryobasidiaceae, and placed it in a new order, the Botryobasidiales (whi ...

Cantharellales
The Cantharellales are an order of fungi in the class Agaricomycetes. The order includes not only the chanterelles (Cantharellaceae), but also some of the tooth fungi (Hydnaceae), clavarioid fungi ( Aphelariaceae and Clavulinaceae), and corticioid fungi ( Botryobasidiaceae). Species within the order are variously ectomycorrhizal, saprotrophic, associated with orchids, or facultative plant pathogens. Those of economic importance include edible and commercially collected ''Cantharellus'', ''Craterellus'', and ''Hydnum'' species as well as crop pathogens in the genera '' Ceratobasidium'' and '' Thanatephorus'' (''Rhizoctonia''). Taxonomy The order was originally proposed in 1926 by German mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota having "stichic" basidia (basidia with nuclear spindles arranged longitudinally). On this basis, he included three families within the Cantharellales: the Cantharellaceae (including the Hydnaceae), the Clavul ...

Erast Parmasto
Erast Parmasto (28 October 1928 – 24 April 2012) was a noted Estonian mycologist, bioscientist and botanist and onetime director of the Estonian Institute of Zoology and Botany. Parmasto was born in Nõmme. He became a member of the Estonian Institute of Zoology and Botany in 1950 and served as its director from 1985 to 1990. His establishment of a mushroom herbarium in 1950 has since seen recognition of 160,000 samples, 37,000 of which Parmasto himself collected. Parmasto published more than 150 papers and 200 articles during his academic career and his works are commonly used in popular scientific and academic journals in Estonia. His expertise in the field of mycology has resulted in him being nicknamed "Seenevana", or the "grand old man of mushrooms". As a mycologist, the field with which Parmasto was most associated, he was best known for his establishment and enhancement of databases for species of mushrooms within Estonia. He was also the author of the first Estonian-la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uthatobasidium
''Rhizoctonia'' is a genus of fungi in the order Cantharellales. Species form thin, effused, corticioid basidiocarps (fruit bodies), but are most frequently found in their sterile, anamorphic state. ''Rhizoctonia'' species are saprotrophic, but some are also facultative plant pathogens, causing commercially important crop diseases. Some are also endomycorrhizal associates of orchids. The genus name was formerly used to accommodate many superficially similar, but unrelated fungi. Taxonomy History Anamorphs ''Rhizoctonia'' was introduced in 1815 by French mycologist Augustin Pyramus de Candolle for anamorphic plant pathogenic fungi that produce both hyphae and sclerotia. The name is derived from Ancient Greek, ῥίζα (''rhiza'', "root") + κτόνος (''ktonos'', "murder"), and de Candolle's original species, ''Rhizoctonia crocorum'' ( teleomorph ''Helicobasidium purpureum''), is the causal agent of violet root rot of carrots and other root vegetables.

Hymenochaetales
The Hymenochaetales are an order of fungi in the class Agaricomycetes. The order in its current sense is based on molecular research and not on any unifying morphological characteristics. According to one 2008 estimate, the Hymenochaetales contain around 600 species worldwide, mostly corticioid fungi and poroid fungi, but also including several clavarioid fungi and agarics. Species of economic importance include wood decay fungi in the genera '' Phellinus'' and ''Inonotus'' sensu lato, some of which may cause losses in forestry. Therapeutic properties are claimed for ''Inonotus obliquus'' ("chaga") and ''Phellinus linteus'', both of which are now commercially marketed. Taxonomy History The order was proposed in 1977 to recognize the family Hymenochaetaceae at a higher taxonomic rank. As originally conceived, species within the Hymenochaetales had several morphological features in common, notably brown or brownish basidiocarps (fruit bodies) that turn black in alkali, hyphae l ...

Corticiales
The Corticiales are an order of fungi in the class Agaricomycetes. The order is composed of corticioid fungi. Species within the order are generally saprotrophic, most of them wood-rotters, but several are parasitic on grasses or lichens. Plant pathogens of economic importance include '' Erythricium salmonicolor'', ''Laetisaria fuciformis'', '' Waitea circinata'', '' Waitea oryzae'', and '' Waitea zeae''. Taxonomy The order was established in 2007 by Swedish mycologist Karl-Henrik Larsson, based on molecular phylogenetic research. It includes the Corticiaceae (the type family) as well as the Dendrominiaceae, Punctulariaceae, and Vuilleminiaceae. Habitat and distribution The order is cosmopolitan and contains around 150 species of fungi worldwide. The majority of species in the Corticiales are saprotrophs, most of them wood-rotters, typically found on dead attached branches. Some species of ''Laetisaria'' are facultative or obligate parasites of grasses; some species o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Sequences
A nucleic acid sequence is a succession of bases signified by a series of a set of five different letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence has capacity to represent information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as ''primary sequence''. Conversely, there is no parallel concept of secondary or tertiary sequence. Nucleotides Nucleic acids consis ...

Cladistic
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Stereales
The Russulales are an order of the Agaricomycetes, (which include the agaric genera '' Russula'' and ''Lactarius'' and their polyporoid and corticioid relatives). According to the ''Dictionary of the Fungi'' (10th edition, 2008), the order consists of 12 families, 80 genera, and 1767 species. According to ''Species Fungorum'' (January 2016), the order contains 13 families, 117 genera (16 not assigned to a family), and 3,060 species. Russuloid agarics represent an independent evolutionary line of agarics, not directly related to the Agaricales. This group also includes a number of russuloid hypogeous fungi, polypores such as ''Bondarzewia'', some tooth fungi (e.g. ''Auriscalpium vulgare''), and club fungi e.g. ''Artomyces''. Basidiospores in this group are typically ornamented with amyloid warts or reticulation but a few exceptions are known, e.g. ''Heterobasidion annosum''. The genus '' Clavicorona'' was often treated in the Russulales, but its type species, '' C. taxophila'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Waitea
''Waitea'' is a genus of fungi in the family Corticiaceae. Basidiocarps (fruit bodies) are corticioid, thin, effused, and web-like, but species are more frequently encountered in their similar but sterile anamorphic states. Several species are plant pathogens, causing commercially significant damage to cereal crops and amenity turf grass A lawn is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawnmower (or sometimes grazing animals) and used for aesthetic and recreational purposes.

Candelabrochaete
''Candelabrochaete'' is a genus of crust fungi in the family Phanerochaetaceae. Taxonomy The genus was circumscribed by French mycologist Jacques Boidin in 1970. He originally included two species, '' C. langloisii'', and the type, '' C. africana''. Description Similar to the genus ''Phanerochaete'', ''Candelabrochaete'' features simple septa in the subicular hyphae and at the base of the basidia, and hyaline, thin-walled, nonamyloid spores. Several features distinguish ''Candelabrochaete'' from ''Phanerochaete''. These include small, cylindrical to club-shaped (clavate) basidia, septate cystidia, a loosely interwoven subiculum (a mat of hyphae from which the fruitbody arises), and a loosely organized hymenium. This latter characteristic gives a farinaceous to woolly appearance to the fruitbodies. Species , Index Fungorum accepts 12 species in ''Candelabrochaete'': *'' Candelabrochaete adnata'' Hjortstam (1995) – Brazil *'' Candelabrochaete africana'' Boidin (197 ...
