Agaricus Xanthodermus
''Agaricus xanthodermus'', commonly known as the yellow-staining mushroom or simply the yellow-stainer, is a mushroom of the genus ''Agaricus'', which displays a strong yellow colouration at the base of the stem when cut. It is poisonous for most people, causing gastrointestinal upset, but can be eaten by some without apparent negative effect. Taxonomy This species was first officially defined under the name ''Agaricus xanthodermus'' in 1876 by Léon Gaston Genevier, in a letter published in the bulletin of the French Botanical Society. Genevier described the ''Agaricus'' mushrooms commonly eaten (perhaps sometimes inadvisedly) in the region of Nantes, and attempted to clarify the distinctions between them. He proposed a detailed reclassification into 5 species, including this new one. Apparently up until that time, these yellow-staining mushrooms were considered to be just varieties of other species which are edible: '' A. arvensis'', A. edulis', and '' A. silvi ...

Léon Gaston Genevier
Léon Gaston Genevier (18 June 1830, in Saint-Clément-de-la-Place, near Angers – 11 July 1880, in Nantes) was a French pharmacist and botanist. During his career, he was a practicing pharmacist in Mortagne-sur-Sèvre and Nantes. Genevier is best remembered for investigations of the genus ''Rubus'' native to the Loire basin. He was an honorary member of the ''Société d'études scientifiques d'Angers''.

Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in ...

Agaricus Moelleri
''Agaricus moelleri'', also known as the inky mushroom, or dark scaled mushroom, is a large mushroom of the genus ''Agaricus''. It appears occasionally in most kinds of woodland, during late summer, in northern temperate zones. Taxonomy For many years ''Agaricus moelleri'' was erroneously accredited with the binomial ''Agaricus placomyces'' by some British authors. The epithet ''placomyces'' was in fact given to a North American species of ''Agaricus'' by Charles Horton Peck in 1878 (now known as ''Agaricus praeclaresquamosus'' A.E.Freeman 1979). The current binomial ''Agaricus moelleri'' was published in 1976 by the Ukrainian mycologist Solomon P. Wasser. Description The cap has a greyish-brown patch in the centre and cold grey-brown scaling on the surrounding off-white background. It is in diameter, and yellows when bruised. It is ovate when young, flattening later. The stem has a drooping ring, and stains yellow very easily when bruised, this colour then changes to brown ...

Agaricus Placomyces
''Agaricus placomyces'' is a toxic basidiomycete fungus of the genus Agaricus. It is found in North America; the Eurasian populations formerly known by the same scientific name are nowadays known as '' A. moelleri'', while the present species may also be referred to as ''A. praeclaresquamosus''. Description ''Agaricus placomyces'' has a cap that is 5–12 cm and varies from convex to broadly convex or nearly flat in age. In addition, the surface of the cap is dry and covered with brownish fibers and scales, especially over the center. Underneath, the cap can be whitish under normal environments, or pinkish in wet weather. Covered with fine, appressed greyish-brown scales and concentrated at the disc, the cap is thick, slowly becoming vinaceous when injured; the odor smells of phenol. The flesh is white, and becomes yellow when placed in KOH. The gills of this mushroom are free from the stem, crowded, and pale grayish-pink, turning brown in age. In addition, the stem is ...

Saprobic
Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (for example ''Mucor'') and soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes; saprotrophic plants or bacterial flora are called saprophytes ( sapro- 'rotten material' + -phyte 'plant'), although it is now believed that all plants previously thought to be saprotrophic are in fact parasites of microscopic fungi or other plants. The process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae. states the purpose of saprotrophs and their internal nutrition, as well as the main two types of fungi that are most often referred to, as well as describes, visually, the process of saprotrophic nutrition through a diagram of hy ...

Anatolia
Anatolia, tr, Anadolu Yarımadası), and the Anatolian plateau, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous w ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Carbolic Soap
Carbolic soap, sometimes referred to as red soap, is a mildly antiseptic soap containing carbolic acid (phenol) and/or cresylic acid (cresol), both of which are phenols derived from either coal tar or petroleum sources. History In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, also known as carbolic acid, which he derived in an impure form from coal tar. In August 1865, Dr. Joseph Lister applied a piece of lint dipped in carbolic acid solution to the wound of an eleven-year-old boy at Glasgow Royal Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg. After four days, he renewed the pad and discovered that no infection had developed, and after a total of six weeks he was amazed to discover that the boy's bones had fused back together, without the danger of suppuration. One of the earliest manufacturers of carbolic soap was F. C. Calvert and Company of Manchester, England, established in 1859 and taken over by Unilever i ...
