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 mining, 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 Julius Vincenz von Krombholz, Krombholz. He became enraptured by mycology and when the Krombholz book was insufficient, he consulted the mycologist Claude Casimir Gillet, ...

1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...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 ne ...

Lactarius Porninsis
''Lactarius porninsis'', the larch milkcap, is a member of the large milk-cap genus ''Lactarius (fungus), 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 botanical name, specific epithet ''porninsis'' honours Rolland's colleague M. Pornin. Description The pileus (mycology), 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 ...

Ganoderma Lionnetii
''Ganoderma'' is a genus of polypore fungi in the family Ganodermataceae that includes about 80 species, many from tropical regions. They may be called ''shelf mushrooms'' or bracket fungi and have a high genetic diversity. ''Ganoderma'' can be differentiated from other polypores because they have a double-walled basidiospore. They are used in traditional Asian medicine. Description ''Ganoderma'' are characterized by basidiocarps, which are large, perennial, woody brackets also called "conks". They are lignicolous and leathery either with or without a stem. The fruit bodies typically grow in a fan-like or hoof-like form on the trunks of living or dead trees. They have double-walled, truncate spores with yellow to brown ornamented inner layers. Taxonomy Taxonomic 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'' Cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leccinellum Corsicum
''Leccinellum corsicum'' is a species of bolete fungus in the family Boletaceae. It grows in mycorrhizal symbiosis exclusively with rockroses (''Cistus'' species) in Mediterranean Europe and North Africa. The fungus was originally described as new to science in 1896 by French mycologist Léon Louis Rolland as a species of ''Boletus''. Andreas Bresinsky and Manfred Binder transferred it to the newly circumscribed genus ''Leccinellum'' in 2003. The bolete is edible An edible item is any item that is safe for humans to eat. "Edible" is differentiated from " eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some mushroo ..., and is especially appreciated in Portugal.

Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, 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 (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
