Lactarius Repraesentaneus
''Lactarius repraesentaneus'', commonly known as the northern bearded milkcap, the northern milkcap, or the purple-staining bearded milkcap, is a species of fungus in the family Russulaceae. It has a northerly distribution, and is found in temperate regions of North America and Europe, associated with spruce trees. Distinguishing features of its fruit body include the large orange-yellow cap up to wide, cream to pale yellow gills, and a yellow coarsely-pitted stem that is up to long and thick. Cut fruit bodies ooze a white latex that will stain mushroom tissue lilac to purple. Several chemicals have been isolated and identified from the fruit bodies that can modify the growth of plants, and the mushroom also has antibiotic activity against ''Staphylococcus aureus''. ''L. repraesentaneus'' is poisonous, and consumption causes stomach aches. Taxonomy ''Lactarius repraesentaneus'' was first described by German mycologist Max Britzelmayr in 1885, based on material colle ...

Lapland (Sweden)
Lapland, also known by its Swedish name Lappland (, fi, Lappi, la, Lapponia), is a province in northernmost Sweden. It borders Jämtland, Ångermanland, Västerbotten, Norrbotten, Norway and Finland. Nearly a quarter of Sweden's land area is in Lappland. Lapland originally extended eastward. However, in 1809 the Russian Empire annexed the eastern part of Sweden, and created the Grand Duchy of Finland, which in effect split Lapland into a Swedish part and a Finnish part, both of which still exist today. It primarily consists of Västerbotten County in the south and Norrbotten County in the north, forming the further inland areas of the two counties. Lapland has the coldest climates of Sweden with vast seasonal differences caused by the high latitudes and the interior location. History The history of Lapland is in many ways connected to the history of Norrbotten County and Västerbotten County, since Lapland is a historic region connected to these counties. During the Mi ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Lactarius Dispersus
''Lactarius'' is a genus of mushroom-producing, ectomycorrhizal fungi, containing several Edible mushroom, edible species. The species of the genus, common name, 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 phylogenetics, molecular phylogenetic evidence. Systematics and taxonomy The genus ''Lactarius'' was described by Christian Hendrik Persoon in 1797 with ''Lactifluus piperatus, L. piperatus'' as the original type species. In 2011, ''Lactarius torminosus, 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 ''wikt:lac#Lati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
