Harvey Willson Harkness
Harvey Willson Harkness (May 25, 1821 – July 10, 1901) was an American mycologist and natural historian best known for his early descriptions of California fungal species. Born and raised in Massachusetts and trained as a physician, Harkness came to California during the Gold Rush in 1849. He first set up a medical practice in the mining camp at Bidwell's Bar but moved to Sacramento in 1851. He rose to prominence as physician, educator, real estate developer, and newspaper editor in Sacramento, becoming part of the social circle of early California notables such as Leland Stanford, Charles Crocker, Collis Huntington, and Mark Hopkins. His active interest in school education led to his election as the first president of the Sacramento board of education in 1853. Harkness was a participant in the ceremony in May 1869 that marked the completion of the First transcontinental railroad, representing California and bearing the Golden Spike that was driven in by Leland Stanford ma ...

Pelham, Massachusetts
Pelham is a town in Hampshire County, Massachusetts, United States. The population was 1,280 at the 2020 census. Its ZIP Code is shared with Amherst. Pelham is part of the Springfield, Massachusetts Metropolitan Statistical Area. History Pelham (pronounced "PEL-am"; the "h" is silent) was part of the Equivalent Lands compromise, and was first settled in 1738 by mostly Presbyterian Scotch-Irish immigrants. It was officially incorporated in 1743. The town is named for the Pelham family; Henry Pelham was Prime Minister of the United Kingdom at the time of the town's incorporation. The town is best known as being home to Daniel Shays, leader of Shays' Rebellion, a series of protests against crushing austerity measures in Massachusetts during 1786 and 1787. The rebellion, planned in Conkey's Tavern in town, drew support from many towns in central and western Massachusetts, but it met its practical end when the angry farmers' force refused to fight Governor Bowdoin's army and the ...

Carson City, Nevada
Carson City is an independent city and the capital of the U.S. state of Nevada. As of the 2020 census, the population was 58,639, making it the sixth largest city in Nevada. The majority of the city's population lives in Eagle Valley, on the eastern edge of the Carson Range, a branch of the Sierra Nevada, about south of Reno. The city is named after the mountain man Kit Carson. The town began as a stopover for California-bound immigrants, but developed into a city with the Comstock Lode, a silver strike in the mountains to the northeast. The city has served as Nevada's capital since statehood in 1864; for much of its history it was a hub for the Virginia and Truckee Railroad, although the tracks were removed in 1950. Before 1969, Carson City was the county seat of Ormsby County. That year the state legislature abolished the county and included its territory into a revised city charter for a Consolidated Municipality of Carson City. With the consolidation, the city limits ...

Lassen Peak
Lassen Peak ( ), commonly referred to as Mount Lassen, is a lava dome volcano and the southernmost active volcano in the Cascade Range of the Western United States. Located in the Shasta Cascade region of Northern California, it is part of the Cascade Volcanic Arc, which stretches from southwestern British Columbia to northern California. Lassen Peak reaches an elevation of , standing above the northern Sacramento Valley. It supports many flora and fauna among its diverse habitats, which are subject to frequent snowfall and reach high elevations. Lassen Peak has a volume of , making it one of the largest lava domes on Earth. The volcano arose from the former northern flank of now-eroded Mount Tehama about 27,000 years ago, from a series of eruptions over the course of a few years. The mountain has been significantly eroded by glaciers over the last 25,000 years, and is now covered in talus deposits. On May 22, 1915, a powerful explosive eruption at Lassen Peak devastated near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vascular Plants
Vascular plants (), also called tracheophytes () or collectively Tracheophyta (), form a large group of land plants ( accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants", as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harknessiella Purpurea
''Harknessiella'' is a genus of fungi in the class Dothideomycetes. The relationship of this taxon to other taxa within the class is unknown (''incertae sedis''). This is a monotypic genus, containing the single species ''Harknessiella purpurea''. It was named after Harvey Willson “H.W.” Harkness. The genus was circumscribed by Pier Andrea Saccardo Pier Andrea Saccardo (23 April 1845 in Treviso, Treviso – 12 February 1920 in Padua) was an Italian botanist and mycologist.

Ascomycete
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomycetes ...

Phytopathogenic
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
