Léon Louis Rolland
Léon Louis Rolland (10 December 1841 – 11 June 1912) was a French mycologist. Early life Rolland, whose father was an engineer and director of the coal mines in the region, began his secondary education at the lycée (high school) of Angers, then that of Meaux, and finally the famous Collège-lycée Jacques-Decour in Paris, then called the Collège Rollin, where he took the baccalauréat. After that from 1866 to 1879 he spent several years in Le Havre, where his father was at that time first deputy. Meanwhile, Rolland developed an extreme passion for mathematics to such an extent that his health suffered and he was forced to give it up and take a break. He continued to live in Le Havre and after the death of his father there he got to know a pharmacist who studied mushrooms using the book by Krombholz. He became enraptured by mycology and when the Krombholz book was insufficient, he consulted the mycologist Gillet who became a close acquaintance. In 1879 he moved to P ...

Chamonix
Chamonix-Mont-Blanc ( frp, Chamôni), more commonly known as Chamonix, is a commune in the Haute-Savoie department in the Auvergne-Rhône-Alpes region of southeastern France. It was the site of the first Winter Olympics in 1924. In 2019, it had a population of 8,640. Situated to the north of Mont Blanc, between the peaks of the Aiguilles Rouges and the notable Aiguille du Midi, Chamonix is one of the oldest ski resorts in France. The Chamonix commune is popular with skiers and mountain enthusiasts. Via the cable car lift to the Aiguille du Midi it is possible to access the off-piste ( backcountry) ski run of the ''Vallée Blanche''. Name The name Campum munitum, meaning fortified plain or field, had been used as early as 1091. By 1283 the name had been abbreviated to a similar form to the modern Chamonis. Other forms through the ages include Chamouny in 1581, Chamony in 1652, Chamouni in 1786, and the particular spelling Chamonix from 1793. Status Chamonix is the fourth-lar ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleurotus Cornucopiae
''Pleurotus cornucopiae'' is a species of edible fungus in the genus ''Pleurotus'', It is quite similar to the better-known ''Pleurotus ostreatus'', and like that species is cultivated and sold in markets in Europe and China, but it is distinguished because its gills are very decurrent, forming a network on the stem. Naming The species name means "of the Cornucopia" (horn of plenty), which is appropriate since the mushrooms are edible and sometimes take on a shape similar to a drinking horn. The original definition of this species, or basionym, was made by Jean-Jacques Paulet in 1793 as ''Dendrosarcos cornucopiae''. At a time when most gilled mushrooms were lumped into genus ''Agaricus'', Paulet invented genus ''Dendrosarcos'', later Latinised to ''Dendrosarcus'', for those having an excentric or missing stipe. In fact those fungi have not been found to be a closely related group, and today the name only has historical interest, though the taxonomic rules imply that it still n ...

Lactarius Porninsis
''Lactarius porninsis'', the larch milkcap, is a member of the large milk-cap genus ''Lactarius'' in the order Russulales. It is found in Europe and Asia, where it grows in a mycorrhizal association with larch. Taxonomy The species was described by French botanist Léon Louis Rolland in 1889. Rolland collected the species in Zermatt, Switzerland. ''Lactarius porninae'' is an orthographic variant. Otto Kuntze placed it in the genus '' Lactifluus'' in 1898. The specific epithet ''porninsis'' honours Rolland's colleague M. Pornin. Description The cap is initially hemispherical with a margin that is rolled inward, later flattening to become convex or flat with a depressed center and margin that curves upward slightly; it reaches in diameter. The cap surface has a felt-like texture and is slightly sticky to the touch. Its colour is orange to yellow-brown or orange-brown, with concentric rings that are palest near the margin. The thin, crowded gills have an adnate to slightly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ganoderma Lionnetii
''Ganoderma'' is a genus of polypore fungi in the family Ganodermataceae that includes about 80 species, many from tropical regions. They have a high genetic diversity and are used in traditional Asian medicines. ''Ganoderma'' can be differentiated from other polypores because they have a double-walled basidiospore. They may be called ''shelf mushrooms'' or bracket fungi. Etymology The name ''Ganoderma'' is derived from the Greek ''ganos''/γάνος "brightness, sheen", hence "shining" and ''derma''/δέρμα "skin". History The genus ''Ganoderma'' was established as a genus in 1881 by Karsten and included only one species, ''G. lucidum'' (Curtis) Karst. Previously, this taxon was characterized as ''Boletus lucidus'' Curtis (1781) and then ''Polyporus lucidus'' (Curtis) Fr. (1821) (Karsten 1881). The species ''P. lucidus'' was characterized by having a laccate (shiny or polished) pileus and stipe, and this is a character that Murrill suspected was the reason for Karsten's ...

Taxonomy (biology)
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 a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the ...
