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.

Waitea Circinata
''Waitea circinata'' is a species of fungus in the family Corticiaceae. Basidiocarps (fruit bodies) are corticioid, thin, effused, and web-like, but the fungus is more frequently encountered in its similar but sterile anamorphic state. ''Waitea circinata'' is best known as a plant pathogen, causing commercially significant damage ( brown ring patch) to amenity turf grass. Taxonomy ''Waitea circinata'' was originally described from Australia in 1962, where it was found growing on the undersides of clods of earth in a wheat field. The new genus ''Waitea'', named after the Waite Agricultural Research Institute in Adelaide, was created to accommodate the species. Because of its morphological similarity to species of ''Rhizoctonia'', ''Waitea circinata'' was presumed to belong within the Ceratobasidiaceae, but phylogenetic analysis of DNA sequences has shown that it actually belongs in the Corticiaceae and is close to species of ''Laetisaria'' (which are also grass pathogens).

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] |
Waitea Oryzae
''Waitea oryzae'' is a species of fungus in the family Corticiaceae. Basidiocarps (fruit bodies) are corticioid, thin, effused, and web-like, but the fungus is more frequently encountered in its similar but sterile anamorphic state. ''Waitea oryzae'' is best known as a plant pathogen, causing commercially significant leaf and sheath spots of rice and other cereals. Taxonomy ''Rhizoctonia oryzae'' was originally described on ''Oryza sativa'' (rice) from Louisiana in 1938, but was invalidly published. It was later considered to be the anamorph (asexual state) of ''Waitea circinata ''Waitea circinata'' is a species of fungus in the family Corticiaceae.

Corticiaceae
The Corticiaceae are a family of fungi in the order Corticiales. The family formerly included almost all the corticioid (patch- or crust-forming) fungi, whether they were related or not, and as such was highly artificial. In its current sense, however, the name Corticiaceae is restricted to a comparatively small group of corticioid genera within the Corticiales. Taxonomy History The German mycologist Wilhelm Gustav Franz Herter first published the Corticiaceae in 1910 to accommodate species of hymenomycetes that produced basidiocarps (fruit bodies) which were effused (spread out and patch-like) and had a more or less smooth hymenophore (spore-bearing surface). Since this definition was vague, superficial, and covered a large range of unrelated fungi, the Corticiaceae, though widely adopted, were also widely recognized as an unnatural grouping. Indeed, in a 1964 survey of families, Donk considered the Corticiaceae to be "a nice example of how extremely artificial taxa can be". ...

Waitea Zeae
''Waitea zeae'' is a species of fungus in the family Corticiaceae. Basidiocarps (fruit bodies) are corticioid, thin, effused, and web-like, but the fungus is more frequently encountered in its similar but sterile anamorphic state. ''Waitea zeae'' is best known as a plant pathogen, causing commercially significant damage to cereals, grasses, and a wide range of other plants. Taxonomy ''Rhizoctonia zeae'' was originally described from Florida in 1934. It was later considered to be the anamorph (asexual state) of ''Waitea circinata ''Waitea circinata'' is a species of fungus in the family Corticiaceae.

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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 motility, 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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidiocarps
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye (especially those with a more or less agaricoid morphology) are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles. Structure All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi. In more complex basidiocarps, there is differentiation into a stipe, a pileus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
