Tulasnellaceae
The Tulasnellaceae are a family of fungi in the order Cantharellales. The family comprises mainly effused (patch-forming) fungi formerly referred to the " jelly fungi" or heterobasidiomycetes. Species are wood- or litter-rotting saprotrophs, but many are also endomycorrhizal associates of orchids and some have also been thought to form ectomycorrhizal associations with trees and other plants. Taxonomy History The family was described in 1897 by the Swedish botanist and mycologist Hans Oscar Juel to accommodate species of fungi producing basidiocarps (fruit bodies) having distinctive basidia with grossly swollen sterigmata. He included two genera: '' Tulasnella'' itself and the poroid genus ''Muciporus'' (the latter subsequently found to be no more than ''Tulasnella'' species growing over the surface of old polypores). In 1900, the French mycologist Narcisse Patouillard included the Tulasnellaceae within the heterobasidiomycetes or " jelly fungi" and in 1922 British m ...

Tulasnella Violea
''Tulasnella violea'' is a species of fungus in the order Cantharellales. Basidiocarps (fruit bodies) are typically smooth, ceraceous (waxy), violet-pink or lilaceous to grey, and occur on the underside of fallen branches and logs. It is one of the more conspicuous ''Tulasnella'' species and appears to be distributed worldwide. Though normally saprotrophic, ''Tulasnella violea'' can form a mycorrhizal association with orchids. Taxonomy The species was originally described in 1883 by French mycologist Lucien Quélet who emphasized the lilac-pink colour of the fruit bodies and gave basidiospore measurements, but failed to notice the distinctive basidia and placed it among the corticioid fungi in the old form genus ''Hypochnus''. The species was transferred to ''Tulasnella'' by French mycologists Hubert Bourdot and Amédée Galzin in 1909. In his 1933 review of the Tulasnellaceae American mycologist Donald P. Rogers extended the concept of ''T. violea'', which he considered "highl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tulasnella
''Tulasnella'' is a genus of effused (patch-forming) fungi in the order Cantharellales. Basidiocarps (fruit bodies), when visible, are typically smooth, ceraceous (waxy) to subgelatinous, frequently lilaceous to violet-grey, and formed on the underside of fallen branches and logs. They are microscopically distinct in having basidia with grossly swollen sterigmata (or epibasidia) on which basidiospores are formed. One atypical species, '' Tulasnella aurantiaca'', produces orange to red, gelatinous, pustular anamorphs on wood. Some species form facultative mycorrhizas with orchids and liverworts. Around 80 species of ''Tulasnella'' are known worldwide. Taxonomy History ''Tulasnella'' was originally circumscribed by German mycologist Joseph Schröter in 1888, partly based on an earlier illustration by Charles Tulasne, after whom the new genus was named. Schröter believed the unusual basidia sufficiently distinct to warrant the creation of a new genus which he considered intermedi ...

Cantharellales
The Cantharellales are an order (biology), order of fungi in the class (biology), 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 pathology, plant pathogens. Those of economic importance include edible mushroom, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genera
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineag ...

Cosmopolitan Distribution
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales ( orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon (usually a species) is said to have a ''cosmopolitan'' distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove (commonly referred to as a ' pigeon'), in addition to having been bred domestically for centuries, now occurs in most urban areas around the world. The extreme opposite of a cosmopolitan species is an endemic (native) species, or one foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphytic
An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. In some cases, a rainforest tree's epiphytes may total "several tonnes" (several long tons). They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corticioid Fungi
The corticioid fungi are a group of fungi in the Basidiomycota typically having effused, smooth basidiocarps (fruit bodies) that are formed on the undersides of dead tree trunks or branches. They are sometimes colloquially called crust fungi or patch fungi. Originally such fungi were referred to the genus '' Corticium'' ("corticioid" means ''Corticium''-like) and subsequently to the family ''Corticiaceae'', but it is now known that all corticioid species are not necessarily closely related. The fact that they look similar is an example of convergent evolution. Since they are often studied as a group, it is convenient to retain the informal (non-taxonomic) name of "corticioid fungi" and this term is frequently used in research papersLarsson K-H, Larsson E, Koljalg U. (2004). High phylogenetic diversity among corticioid homobasidiomycetes. ''Mycological Research'' 108: 983–1002. and other texts.

Ceratobasidiaceae
The Ceratobasidiaceae are a family of fungi in the order Cantharellales. All species within the family have basidiocarps (fruit bodies) that are thin and effused. They have sometimes been included within the corticioid fungi or alternatively within the " heterobasidiomycetes". Species are saprotrophic, but some are also facultative plant pathogens or are associated with orchid mycorrhiza. Genera of economic importance include ''Ceratobasidium'' and ''Rhizoctonia'', both of which contain plant pathogenic species causing diseases of commercial crops and turf grass. Taxonomy The family was created in 1948 by American mycologist G.W. Martin to accommodate species of corticioid fungi with heterobasidiomycete features (elongated sterigmata and basidiospores that give rise to secondary spores). He restricted the Ceratobasidiaceae to the genus ''Ceratobasidium'', though including within the genus species later placed in '' Thanatephorus'' and '' Oliveonia''. In 1981, Jülich created ...

DNA Sequences
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, 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 represents genetic 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladistic
Cladistics ( ; from Ancient Greek 'branch') 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 ...
