Job Bicknell Ellis
Job Bicknell Ellis (January 21, 1829 – December 30, 1905) was a pioneering North American mycologist known for his study of ascomycetes, especially the grouping of fungi called the Pyrenomycetes (known today as the Sordariomycetes). Born and raised in New York, he worked as a teacher and farmer before developing an interest in mycology. He collected specimens extensively, and together with his wife, prepared 200,000 sets of dried fungal samples that were sent out to subscribers in series between 1878 and 1894. Together with colleagues William A. Kellerman and Benjamin Matlack Everhart, he founded the ''Journal of Mycology'' in 1885, forerunner to the modern journal ''Mycologia''. He described over 4000 species of fungi, and his collection of over 100,000 specimens is currently housed at the herbarium of the New York Botanical Gardens. Ellis had over 100 taxa of fungi named in his honor. Life Ellis was born in Potsdam, New York on January 21, 1829 to parents Freeman Ellis and S ...

Benjamin Matlack Everhart
Benjamin Matlack Everhart (born 24 April 1818; died 22 September 1904) was a United States mycologist. Biography His father, William Everhart, the son of a Revolutionary soldier, was a merchant, and a member of congress in 1853-55. Benjamin was educated in private schools in West Chester, and spent his early life in mercantile business there and in Charleston, South Carolina, making a comfortable fortune. From boyhood, he was an ardent student of botany, and after retiring from business in 1867 he devoted himself almost entirely to that science, particularly to cryptogamic botany. In connection with J. B. Ellis, of New Jersey, he was active in issuing yearly fifty volumes, called ''The Century of North American Fungi'', each volume describing 100 species. At the same time, with William A. Kellerman, of Kansas, they published the ''Journal of Mycology''. He discovered many new fungi. The genus ''Everhartia'' was named by Pier Andrea Saccardo Pier Andrea Saccardo (23 April 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 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 organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Spot
A leaf spot is a limited, discoloured, diseased area of a leaf that is caused by fungal, bacterial or viral plant diseases, or by injuries from nematodes, insects, environmental factors, toxicity or herbicides. These discoloured spots or lesions often have a centre of necrosis (cell death).Horst, R. (2008). Westcott’s Plant Disease Handbook (Seventh Edition.). Springer Netherlands. Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves.Lucas, G., & Campbell, L. (1992). Introduction to Plant Diseases Identification and Management (2nd ed. 1992.). Springer US. https://doi.org/10.1007/978-1-4615-7294-7 Description Leaf spots are a type of plant disease that are usually caused by pathogens and sometimes othe ...

Persimmon
The persimmon is the edible fruit of a number of species of trees in the genus ''Diospyros''. The most widely cultivated of these is the Oriental persimmon, ''Diospyros kaki'' ''Diospyros'' is in the family Ebenaceae, and a number of non-persimmon species of the genus are grown for ebony timber. In 2019, China produced 75% of the world total of persimmons. Description Like the tomato, persimmons are not commonly considered to be berries, but Morphology (biology), morphologically the fruit is in fact a berry (botany), berry. The tree ''Diospyros kaki'' is the most widely cultivated species of persimmon. Typically the tree reaches in height and is round-topped. It usually stands erect, but sometimes can be crooked or have a willowy appearance. The leaves are long, and are Glossary of leaf morphology#oblong, oblong in shape with brown-hairy Petiole (botany), petioles in length. They are leathery and glossy on the upper surface, brown and silky underneath. The leaves are dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diospyros Hispida
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". Muddled translations sometimes give rise to curious and inappropriate interpretations such as "God's pear" and "Jove's fire". The genus is a large one and ...

Diospyros Kaki
''Diospyros kaki'', the Oriental persimmon, Chinese persimmon, Japanese persimmon or kaki persimmon, is the most widely cultivated species of the genus '' Diospyros''. Although its first botanical description was not published until 1780,Published in ''Nova Acta Soc. Sc. Upsal.'' iii. 208, author Carl Peter Thunberg, hunb.(1780); later in ''Fl. Jap.'' 157, author Thunb. (1784). ''D. kaki'' is among the oldest cultivated plants, having been in use in China for more than 2000 years. Names Whether the species was first described by Carl Peter Thunberg or Carl Linnaeus the Younger is disputed. The scientific name ''Diospyros kaki'' L. f. may be used erroneously for this plant. However, ''Diospyros kaki'' L. f., published in 1781, is a later homonym of ''Diospyros kaki'' Thunb., published in 1780. So the name ''Diospyros kaki'' L. f. is taxonomically illegitimate and not accepted. It is called ''shi'' (柿) in Chinese, ''kaki'' (柿) in Japanese, ''gam'' (감) in Korean, kesemek i ...

Diospyros Lotus
''Diospyros lotus'', with common names date-plum, Caucasian persimmon, or lilac persimmon, is a widely cultivated species of the genus ''Diospyros'', native to subtropical southwest Asia and southeast Europe. Its English name derives from the small fruit, which have a taste reminiscent of both plums and dates. It is among the oldest plants in cultivation. Distribution and ecology The species area extends from East Asia to the west of the Mediterranean, down to Spain. The date-plum is native to southwest Asia and southeast Europe. It was known to the ancient Greeks as "God's fruit" (, ''Diós pŷrós''), hence the scientific name of the genus. Its English name probably derives from Persian ''Khormaloo'' خرمالو literally "date-plum", referring to the taste of this fruit which is reminiscent of both plums and dates. The fruit is called ''Amlok'' املوک in Pakistan and consumed dried. This species is one candidate for the "lotus tree" mentioned in ''The Odyssey'': it was ...

Diospyros Texana
''Diospyros texana'' is a species of persimmon that is native to central, south and west Texas and southwest Oklahoma in the United States, and eastern Chihuahua, Coahuila, Nuevo León, and Tamaulipas in northeastern Mexico. Common names include Texas persimmon, Mexican persimmon and the more ambiguous " black persimmon". It is known in Spanish as chapote, chapote manzano, or chapote prieto, all of which are derived from the Nahuatl word '' tzapotl''. That word also refers to several other fruit-bearing trees.

Diospyros Tupru
''Diospyros melanoxylon'', the Coromandel ebony or East Indian ebony, is a species of flowering tree in the family Ebenaceae native to India and Sri Lanka; it has a hard, dry bark. Its common name derives from Coromandel, the coast of southeastern India. Locally it is known as ''temburini'' or by its Hindi name ''tendu''. In Odisha, Jharkhand, and Assam, it is known as ''kendu''. In Andhra Pradesh, and Telengana it is known as ''tuniki'. The leaves can be wrapped around tobacco to create the Indian ''beedi'', which has outsold conventional cigarettes in India. The olive-green fruit of the tree is edible Pharmacology The leaf of the tree contains valuable flavones. The pentacyclic triterpenes found in the leaves possess antimicrobial properties, while the bark shows antihyperglycemic activity. The bark of four ''Diospyros'' species found in India has been determined to have significant antiplasmodial effects against ''Plasmodium falciparum'', which causes malaria in humans. ...
