Henry Curtis Beardslee
Henry Curtis Beardslee (28 September 1865 – 1 January 1948) was an American mycologist. He published several works with William Chambers Coker, and did a lot of work in Florida with Gertrude Simmons Burlingham after they both retired there. Beardslee graduated from Painesville High School, in Painesville, Ohio in 1883. He graduated from Western Reserve University in 1889. He was an instructor at Asheville School for boys. Beardslee's father, also named Henry Curtis Beardslee (1807–1884), was also a botanist.

Painesville, Ohio
Painesville is a city in and the county seat of Lake County, Ohio, United States, located along the Grand River northeast of Cleveland. Its population was 19,563 at the 2010 census. Painesville is the home of Lake Erie College, Morley Library, and the Historic Downtown Painesville Recreation Area. History Painesville was settled shortly after the Revolutionary War. It was still considered part of the Connecticut Western Reserve. General Edward Paine (1746–1841), a native of Bolton, Connecticut, who had served as a captain in the Connecticut militia during the war, and John Walworth arrived in 1800 with a party of sixty-six settlers, among the first in the Western Reserve. General Paine later represented the region in the territorial legislature of the Northwest Territory. In 1800 the Western Reserve became Trumbull County and at the first Court of Quarter Sessions, the county was divided into eight townships. The smallest of these townships was named Painesvill ...

Lactarius Floridanus
''Lactarius'' is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus ''Russula'', their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus ''Lactifluus'' has been separated from ''Lactarius'' based on molecular phylogenetic evidence. Systematics and taxonomy The genus ''Lactarius'' was described by Christian Hendrik Persoon in 1797 with '' L. piperatus'' as the original type species. In 2011, '' L. torminosus'' was accepted as the new type of the genus after the splitting-off of ''Lactifluus'' as separate genus. The name "''Lactarius''" is derived from the Latin ''lac'', "milk". Placement within Russulaceae Molecular phylogenetics uncovered that, while macromorphologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russula Flava
''Russula'' is a very large genus composed of around 750 worldwide species of ectomycorrhizal mushrooms. They are typically common, fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include usually brightly coloured caps, a white to dark yellow spore print, brittle, attached gills, an absence of latex, and absence of partial veil or volva tissue on the stem. Microscopically, the genus is characterised by the amyloid ornamented spores and flesh (trama) composed of spherocysts. Members of the related genus ''Lactarius'' have similar characteristics but emit a milky latex when their gills are broken. The genus was described by Christian Hendrik Persoon in 1796. Taxonomy Christian Hendrik Persoon first circumscribed the genus ''Russula'' in his 1796 work ''Observationes Mycologicae'', and considered the defining characteristics to be the fleshy fruit bodies, depressed ...

Mycena Glutinosa
''Mycena'' is a large genus of small saprotrophic mushrooms that are rarely more than a few centimeters in width. They are characterized by a white spore print, a small conical or bell-shaped cap, and a thin fragile stem. Most are gray or brown, but a few species have brighter colors. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like ''Mycena haematopus'', exude a latex when the stem is broken, and many species have a chlorine or radish-like odor. Overview ''Mycenas'' are hard to identify to species and some are distinguishable only by microscopic features such as the shape of the cystidia. Some species are edible, while others contain toxins, but the edibility of most is not known, as they are likely too small to be useful in cooking. ''Mycena pura'' contains the mycotoxin muscarine, but the medical significance of this is unknown. Over 58 species are known to be bioluminescent, ...

Lepiota Parva
''Lepiota'' is a genus of gilled mushrooms in the family Agaricaceae. All ''Lepiota'' species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps (fruit bodies) are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of ''Lepiota'' are currently recognized worldwide. Many species are poisonous, some lethally so. Taxonomy History ''Agaricus'' section ''Lepiota'' was originally published in 1797 by South African-born mycologist Christian Hendrik Persoon. It was subsequently raised to the rank of genus by Samuel Frederick Gray. As originally conceived, the genus was a mix of agarics with rings on their stems, including species now placed in ''Armillaria'', ''Cortinarius'', and ''Pholiota''. In 1822, however, the influential Swedish mycologist Elias Magnus Fries restricted ''Lepiota'' to white-spored, ringed agarics. Based on macro- and micromorphology, later authors gradually refined the gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
