Tilletiales
The Tilletiales are an order of smut fungi in the class Exobasidiomycetes. It is a monotypic order, consisting of a single family, the Tilletiaceae, which contains seven genera. The roughly 150 species in the Tilletiales all infect hosts of the grass family, except for species of '' Erratomyces'', which occur on legumes A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock fo ....

Salmacisia
''Salmacisia'' is a fungal genus in the family Tilletiaceae. It is a monotypic genus, containing the single species ''Salmacisia buchloëana'', first described as ''Tilletia buchloëana'' in 1889, and renamed in 2008. Plants infected by the fungus undergo a phenomenon known as "parasitically induced hermaphroditism", whereby ovary development is induced in otherwise male plants. Because of the pistil-inducing effects of the fungus, the authors have named the species pistil smut; it is the only species in the order Tilletiales known to have hermaphroditic effects. Taxonomy and history In 1889 American mycologist William Ashbrook Kellerman and his student Walter T. Swingle discovered a species of smut that was able to change the sex of its host; the host plant, in this case buffalograss (''Buchloë dactyloides''), produced ovaries in flowers of plants that were otherwise male. They named the fungus ''Tilletia buchloëana'', a generic placement they considered apt because of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exobasidiomycetes
The Exobasidiomycetes are a class of fungi sometimes associated with the abnormal outgrowths of plant tissues known as galls. The class includes ''Exobasidium camelliae'' Shirai, the camellia leaf gall and ''Exobasidium vaccinii'' Erikss, the leaf and flower gall. There are eight orders in the Exobasidiomycetes, including the Ceraceosorales, Doassansiales, Entylomatales, Exobasidiales, Georgefischeriales, Malasseziales, Microstromatales and the Tilletiales. Four of the eight orders include smut fungi. The families Ceraceosoraceae and Malasseziaceae ''Malassezia'' (formerly known as ''Pityrosporum'') is a genus of fungi. It is the sole genus in family (biology), family Malasseziaceae, which is the only family in order (biology), order Malasseziales, itself the single member of class (biology ... were formally validated in 2009 for the orders Ceraceosorales and Malasseziales, respectively.

Karnal Bunt
Karnal bunt (also known as partial bunt) is a fungal disease of wheat, durum wheat, and triticale. The smut fungus ''Tilletia indica'', a basidiomycete, invades the kernels and obtains nutrients from the endosperm, leaving behind waste products with a disagreeable odor that makes bunted kernels too unpalatable for use in flour or pasta. While Karnal bunt generally does not lead to devastating crop losses, it has the potential to dramatically decrease yield and poses additional economic concerns through quarantines which limit the export of suspected infectious wheat products from certain areas, including the U.S. Several chemical control methods exist for Karnal bunt of wheat, but much work remains to be done in identifying resistant host varieties. Morphology Teliospore Teliospore ultrastructure was characterized by electron microscopy by Roberson & Luttrell in 1987. Hosts and symptoms Karnal bunt attacks durum wheat, rye, and triticale, a hybrid of wheat and rye. Despite it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ustilaginomycotina
The Ustilaginomycotina is a subdivision within the division Basidiomycota of the kingdom Fungi. It consists of the classes Ustilaginomycetes and Exobasidiomycetes, and in 2014 the subdivision was reclassified and the two additional classes Malasseziomycetes and Moniliellomycetes added. The name was first published by Doweld in 2001; Bauer and colleagues later published it in 2006 as an isonym. Ustilagomycotina and Agaricomycotina are considered to be sister groups, and they are in turn sister groups to the subdivision Pucciniomycotina. Ustilaginomycotina comprises 115 genera with more than 1700 species. The subdivision is mostly plant parasites on vascular plants, and the distribution of the subdivision is therefore restricted to the distribution of the host. The group is also called the true smut fungi because of the production of teliospores. The name smut is still used as a term since it circumscribes the organization and life cycle of Ustilaginomycotina, but it is not a tax ...

Conidiosporomyces
''Conidiosporomyces'' is a genus of fungi in the smut family Tilletiaceae. The genus was described in 1992 to accommodate the species formerly known as ''Tilletia ayresii'', first described by British naturalist Miles Joseph Berkeley in 1899. The species ''C. verruculosus'' (formerly ''Ustilago verruculosa'') was described in 1993. Species in the genus are plant pathogens that affect various grasses. Description The fruiting structures (technically called sori) of ''Conidiosporomyces'' species grow in the ovaries of various grass species. They are swollen masses of spores with an apical opening, surrounded by a sac-like membrane comprising tissue of both host and fungal origin. The structure supports a central semi-powdery mass made of spores, sterile cells, and balls of conidia. The fruiting structure lacks a sterile central axis known as a columella. The spores are thick-walled, spherical or broadly elliptical, buff colored, with surface ornamentations, and dimensions of ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 taxonomy (biology), 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 ...

Monotypic Fungus Taxa
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Basidiomycota Orders
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 forma ...
