Botryorhiza hippocrateae Whetzel & Olive (1917) |
Botryorhiza is a genus of rust fungi in the Chaconiaceae family. The genus is monotypic, containing the single species Botryorhiza hippocrateae, which grows on Hippocratea plants in Brazil and the Caribbean. [2]
Basidiomycota is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya 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 and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores. These specialized spores are called basidiospores. However, some Basidiomycota are obligate asexual reproducers. Basidiomycota that reproduce asexually can typically be recognized as members of this division by gross similarity to others, by the formation of a distinctive anatomical feature, cell wall components, and definitively by phylogenetic molecular analysis of DNA sequence data.
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa.
Gymnosporangium is a genus of heteroecious plant-pathogenic fungi which alternately infect members of the family Cupressaceae, primarily species in the genus Juniperus (junipers), and members of the family Rosaceae in the subfamily Amygdaloideae. The common name cedar-apple rusts has been used for these fungi. According to the Dictionary of the Fungi, there are about 57 species in the genus.
Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales.
Oomycota forms a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms, called oomycetes. They are filamentous and heterotrophic, and can reproduce both sexually and asexually. Sexual reproduction of an oospore is the result of contact between hyphae of male antheridia and female oogonia; these spores can overwinter and are known as resting spores. Asexual reproduction involves the formation of chlamydospores and sporangia, producing motile zoospores. Oomycetes occupy both saprophytic and pathogenic lifestyles, and include some of the most notorious pathogens of plants, causing devastating diseases such as late blight of potato and sudden oak death. One oomycete, the mycoparasite Pythium oligandrum, is used for biocontrol, attacking plant pathogenic fungi. The oomycetes are also often referred to as water molds, although the water-preferring nature which led to that name is not true of most species, which are terrestrial pathogens.
Teliospore is the thick-walled resting spore of some fungi, from which the basidium arises.
The Fungi of Australia form an enormous and phenomenally diverse group, a huge range of freshwater, marine and terrestrial habitats with many ecological roles, for example as saprobes, parasites and mutualistic symbionts of algae, animals and plants, and as agents of biodeterioration. Where plants produce, and animals consume, the fungi recycle, and as such they ensure the sustainability of ecosystems.
Puccinia is a genus of fungi. All species in this genus are obligate plant pathogens and are known as rusts. The genus contains about 4000 species.
Julius Oscar Brefeld, usually just Oscar Brefeld, was a German botanist and mycologist.
The Auriculariales are an order of fungi in the class Agaricomycetes. Species within the order were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps that produce spores on septate basidia. Around 200 species are known worldwide, placed in six or more families, though the status of these families is currently uncertain. All species in the Auriculariales are believed to be saprotrophic, most growing on dead wood. Fruit bodies of several Auricularia species are cultivated for food on a commercial scale, especially in China.
Vladimir Andreevich Tranzschel was a Russian botanist, mycologist and plant pathologist, especially an expert on rust fungi.
Arthuriomyces is a genus of rust fungi in the family Phragmidiaceae. The genus contains three species that are found in North America, Russia, China, and Japan. The genus is named in honor of American botanist Joseph Charles Arthur, noted for his research on rust fungi.
Frommeella (Frommeëlla) is a genus of rust fungi in the family Phragmidiaceae. The widespread genus contains two species.
Chrysomyxa is a genus of rust fungi in the family Coleosporiaceae. The genus, widespread in the Northern Hemisphere, contains about 23 species. Rust fungi in the genus Chrysomyxa occur in boreal forests of the northern hemisphere on Pinaceae,, and most species alternate to angiosperm hosts in the Ericaceae.
Edwin Butterworth Mains (1890–1968) was an American mycologist. He was known for his taxonomic research on the rust fungi (Pucciniomycetes), the genus Cordyceps, and the earth tongues (Geoglossaceae).
Ernst Albert Gäumann was a Swiss botanist and mycologist. Born in Lyss, Canton of Bern, he obtained his early education in Biel, where he experienced both German and French languages and cultures. Studying with Eduard Fischer at the University of Bern, Gäumann received his PhD in 1917 for his research on Peronospora, a genus of water molds. After travels and study in Sweden, the United States, and the East Indies, Gäumann worked as a plant pathologist in Buitenzorg, Java, from 1919 to 1922, and then as a botanist in Zurich for several years. He held a position at the Swiss Federal Institute of Technology from 1927 until his death.
Uromycladium is a genus of rust fungi in the family Pileolariaceae. It was circumscribed by mycologist Daniel McAlpine in 1905. The genus was established by McAlpine for rusts on Acacia with teliospores that clustered at the top of a pedicel.
Frank Dunn Kern was an American plant pathologist and university administrator. He was a faculty member at Pennsylvania State University, holding appointments as Head of the Department of Botany and Dean of the Graduate School. He was an expert on the Pucciniales.
Pucciniosira is a genus of rust fungi belonging to the family Pucciniosiraceae.
