Phyllosticta Concava
''Phyllosticta concava'', also known as opuntia dry rot or prickly pear brown spot, is a species of fungus that infects opuntia cactus, leaving discolored circular depressions in the pads. The species was first formally described by the mycologist Fred Jay Seaver Fred Jay Seaver (14 March 1877 – 21 December 1970) was an American mycologist. He worked at the New York Botanical Garden for 40 years, initially as the Director of Laboratories (1908–1911), then as the Curator (1912–1943), and finally as He ... in 1922.

Saguaro National Park
Saguaro National Park is a List of national parks of the United States, national park of the United States in southeastern Arizona. The park consists of two separate areas—the Tucson Mountain District (TMD), about west of Tucson, Arizona, Tucson, and the Rincon Mountain District (RMD), about east of the city. Both districts preserve Sonoran Desert landscapes, fauna, and flora, including the giant saguaro cactus. The volcanic rocks on the surface of the Tucson Mountain District differ greatly from the surface rocks of the Rincon Mountain District; over the past 30 million years, crustal stretching displaced rocks from beneath the Tucson Mountains of the Tucson Mountain District to form the Rincon Mountains of the Rincon Mountain District. Uplifted, domed, and eroded, the Rincon Mountains are significantly higher and wetter than the Tucson Mountains. The Rincons, as one of the Madrean Sky Islands between the southern Rocky Mountains and the Sierra Madre Oriental in Mexico, su ...

Fred Jay Seaver (14 March 1877 – 21 December 1970) was an American mycologist. He worked at the New York Botanical Garden for 40 years, initially as the Director of Laboratories (1908–1911), then as the Curator (1912–1943), and finally as Head Curator (1943–1948). Between 1907 and 1909 he issued two exsiccatae, ''North Dakota Fungi'' and ''Ascomycetes and lower fungi'', the later with G. W.

He was also an editor of the journal ''Mycologia'' between 1909 and 1947. In 1928, Seaver published ''North American Cup-fungi (Operculates)'', which was expanded with a supplement in 1942 and a second volume in 1951, titled ''North American Cup-fungi (Inoperculates)''. Botanist Herbert Hice Whetzel published '' Seaverinia'' in 1945, named after Seaver, which is a genus of fungi in the family Sclerotiniacea ...

Fungus
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] |
Opuntia
''Opuntia'', commonly called the prickly pear cactus, is a genus of flowering plants in the cactus family Cactaceae, many known for their flavorful fruit and showy flowers. Cacti are native to the Americas, and are well adapted to arid climates; however, they are still vulnerable to alterations in precipitation and temperature driven by climate change. The plant has been introduced to parts of Australia, southern Europe, the Middle East, and northern Africa. ''Prickly pear'' alone is more commonly used to refer exclusively to the fruit, but may also be used for the plant itself; in addition, other names given to the plant and its specific parts include ''tuna'' (fruit), ''sabra'', ''sabbar'', '' nopal'' (pads, plural ''nopales'') from the Nahuatl word , nostle (fruit) from the Nahuatl word , and paddle cactus. The genus is named for the Ancient Greek city of Opus. The fruit and leaves are edible. The most common culinary species is the "Barbary fig" ('' Opuntia ficus-indica ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botryosphaeriaceae
The Botryosphaeriaceae are a family of sac fungi (Ascomycetes), which is the type representative of the order Botryosphaeriales. According to a 2008 estimate, the family contains 26 genera and over 1500 species. Members of this order include notable plant pathogens. Genera This is a list of the genera in the Botryosphaeriaceae, based on a 2022 review and summary of fungal classification by Wijayawardene and colleagues. Following the genus name is the taxonomic authority In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon), and these groups are given ... (those who first circumscribed the genus; standardized author abbreviations are used), year of publication, and the number of species: *'' Alanphillipsia'' – 5 spp. *'' Barriopsis'' – 5 spp. *'' Botryobambusa'' – 2 spp. *'' Botryosphaeria'' – 9 spp. *' ...
