Chaconiaceae
The Chaconiaceae are a family of rust fungi in the order Pucciniales. The family contained 8 genera and 75 species in 2008. By 2020, there were 8 genera and 84 species. Most species have a tropical distribution. '' Maravalia cryptostegiae'' has been used with success as a biocontrol agent against rubber vine in Australia.

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidiomycota
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: agarics, 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 ...

Pucciniomycetes
Pucciniomycetes (formerly known as Urediniomycetidae) is a diverse class of fungi in the subphylum Pucciniomycotina of phylum Basidiomycota. The class contains 5 orders, 21 families, 190 genera, and approximately 8,016 species. It has been estimated that this class contains about one third of all teleomorphic basidiomycetes. Pucciniomycetes contains many economically important plant pathogenic fungal rusts; the order Pucciniales (formerly Uredinales) is the largest clade in this class, representing approximately 7,000 species. Pucciniomycetes are cosmopolitan and can be found in both terrestrial and aquatic environments, although aquatic species are poorly understood. Characteristics Species in the class Pucciniomycetes develop no basidiocarp, karyogamy occurs in a thick-walled resting spore (teliospore), and meiosis occurs upon germination of the teliospore. They have simple septal pores without membrane caps, and disc-like spindle pole bodies. Except for a few species, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pucciniales
Rusts are fungal plant pathogens of the order Pucciniales (previously known as Uredinales) causing plant fungal diseases. An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus '' Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be grown easily in pure culture. Most species of rust fungi are able to infect two different plant hosts in different stages of their life cycle, and may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinia, telia, and basidia in successive stages of reproduction. Each spore type is very host-specific, and can typically infect only one kind of plant. Rust fungi a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monotypic
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. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Anemone Flaccida
''Anemonastrum flaccidum'', the flaccid anemone or soft windflower, is a plant species in the family Ranunculaceae. It is a perennial growing to 0.1 m (0ft 4in). Features Depending on the region, it flowers between March and June. The flowers are about 2 cm in diameter with white calyx. Many stems have two flower stalks characteristically extending from one stem, and this is the origin of the plant's Japanese name (literally, 'two-flowered plant'). The plant spreads with rhizomes, and so it often forms communities. Range ''Anemonastrum flaccidum'' occurs naturally along the Amur River; in Sakhalin; in central, eastern and southern China; in Korea and in Japan. It is sometimes grown as an ornamental plant Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars th ... in places such as Sweden. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elaeagnus Umbellata
''Elaeagnus umbellata'' is known as Japanese silverberry, umbellata oleaster, autumn olive, autumn elaeagnus, spreading oleaster, autumnberry, or autumn berry. The species is indigenous to eastern Asia and ranges from the Himalayas eastwards to Japan. It is a hardy, aggressive invasive species able to readily colonize barren land, becoming a troublesome plant in the central and northeastern United States and Europe. Description ''Elaeagnus umbellata'' grows as a deciduous shrub or small tree, typically up to tall, with a dense crown.Parmar, C. and M.K. Kaushal. 1982. ''Elaeagnus umbellata''. p. 23–25.

Taxa Described In 1984
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
