Exobasidium
''Exobasidium'' is a genus of fungi in the family Exobasidiaceae. The genus has a widespread distribution, especially in northern temperate regions, and contains about 50 species. Many of the species in this genus are plant pathogens that grow on Ericaceae. The comprising fungi are parasitic in nature, especially on various heath plants where they cause galls.

Exobasidium Vaccinii
''Exobasidium vaccinii'', commonly known as “red leaf disease,” or “Azalea Gall,” is a biotrophic species of fungus that causes galls on ericaceous plant species, such as blueberry and azalea (''Vaccinium'' and ''Rhododendron'' spp.). As a member of the Ustilagomycota, it is a basidiomycete closely related to smut fungi. Karl Wilhelm Gottlieb Leopold Fuckel first described the species in 1861 under the basionym ''Fusidium vaccinii,'' but in 1867 Mikhail Stepanovich Voronin (often cited as “Woronin”) later placed it in the genus ''Exobasidium''. The type specimen is from Germany, and it is held in the Swedish Museum of Natural History. Morphology In its pathogenic state, ''E. vacinnii'' causes discoloration and, depending on the host, may cause hypertrophy and hyperplasia on the leaves and meristem, often forming flower-like structures (i.e. “pseudoflowers”). It may also cause green spots on blueberry fruits, which are sometimes tinted red and have occasional w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exobasidium Vexans
''Exobasidium vexans'' is a plant pathogen affecting tea. Blister blight caused by ''Exobasidium vexans'' is a devastating leaf disease in tea (''Camellia sinensis ''Camellia sinensis'' is a species of evergreen shrub or small tree in the flowering plant family Theaceae. Its leaves and leaf buds are used to produce the popular beverage, tea. Common names include tea plant, tea shrub, and tea tree (not to ...'') in almost all tea growing regions in Asia. This disease causes serious crop losses under inclement weather conditions besides affecting quality of made tea. Although tea cultivars show varying degrees of resistance/susceptibility to blister blight, a cultivar showing total resistance to blister blight has not yet been identified. The mature two-celled basidiospores are very easily dislodged from the sterigmata and are usually to be found on the surface of the blister.

Rhododendron Hirsutum
''Rhododendron hirsutum'', commonly known as the hairy alpenrose is one of the species of ''Rhododendron'' native to the mountains of Europe. It occurs widely in the Alps except for the southwestern region (approximately south and west of the Matterhorn), and has become naturalised in parts of the Carpathians. It grows on carbonate-rich soils, whereas its close relative '' R. ferrugineum'' grows on acid soils; where the two occur together, they frequently produce the hybrid Hybrid may refer to: Science * Hybrid (biology), an offspring resulting from cross-breeding ** Hybrid grape, grape varieties produced by cross-breeding two ''Vitis'' species ** Hybridity, the property of a hybrid plant which is a union of two dif ...

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 ...
