Saproamanita
The genus ''Saproamanita'' contains about 24 species of agarics and is one of six genera in the family Amanitaceae. The others are ''Amanita'' (which now includes the synonym '' Torrendia'', a generic name previously applied to sequestrate species), '' Catatrama'', '' Limacellopsis'', '' Zhuliangomyces'' and '' Limacella''. ''Saproamanita'' are the saprophytic species in the Tribe Amaniteae, separately classified from the ectomycorrhizal species in the genus ''Amanita''. ''Saproamanita'' resemble ''Amanita'' and have a pileus, free lamellae, a central stipe, and an annulus with scales and rings below the annulus that are the remnants of the universal veil composed largely of cylindrical to slender clavate inflated hyphal cells mostly scattered in the central stipe region rather than the base. The spores are white and amyloid. DNA molecular evidence for the separation of the saprotrophic genus from the sister genus of symbiotic genus ''Amanita'' was first detected in a study of mu ...

Saproamanita Vittadinii
''Saproamanita vittadinii'', commonly known as the Vittadini's lepidella, is a European saprophyte mushroom classified in the genus ''Saproamanita'' Unlike some ''Amanitas'', this species is known to occur without accompanying woody plant symbionts.From R. E. Tulloss' website 'Amanita vittadinii (Moretti) Vitt. "Vittadini's Lepidella"' It has a general aspect somewhat between ''Macrolepiota'' and ''Armillaria'', but it is characterized by a pure white colour overall (whilst those genera are brownish) and by the squamous (scaly) covering of cap A cap is a flat headgear, usually with a visor. Caps have crowns that fit very close to the head. They made their first appearance as early as 3200 BC. Caps typically have a visor, or no brim at all. They are popular in casual and informal se ... and stipe.(Translated from Spanish to EnglisAmanita vittadinii(Moretti)at www.amanitacesarea.com (by José Cuesta and Jorge Jiménez) References External linksThe genus Amanita should ...

Amanitaceae
The Amanitaceae is a family of mushroom-forming fungi. ''Amanita'' Pers. is one of the most specious and best-known fungal genera. The family, also commonly called the amanita family, is in order Agaricales, the gilled mushrooms. The family consists primarily of the large genus ''Amanita'', but also includes the smaller genera '' Amarrendia'', '' Catatrama'', '' Limacella'', '' Limacellopsis'', '' Saproamanita'', '' Torrendia'' and '' Zhuliangomyces''. Both '' Amarrendia'' and '' Torrendia'' are considered to be synonymous with ''Amanita'' but appear quite different because they are secotioid. The species are usually found in woodlands. The most characteristic emerge from an egg-like structure formed by the universal veil. This family contains several species valued for edibility and flavor, and other deadly poisonous ones. More than half the cases of mushroom poisoning stem from members of this family. The most toxic members of this group have names that warn of the poiso ...

Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Cyprus
Cyprus ; tr, Kıbrıs (), officially the Republic of Cyprus,, , lit: Republic of Cyprus is an island country located south of the Anatolian Peninsula in the eastern Mediterranean Sea. Its continental position is disputed; while it is geographically in Western Asia, its cultural ties and geopolitics are overwhelmingly Southern European. Cyprus is the third-largest and third-most populous island in the Mediterranean. It is located north of Egypt, east of Greece, south of Turkey, and west of Lebanon and Syria. Its capital and largest city is Nicosia. The northeast portion of the island is ''de facto'' governed by the self-declared Turkish Republic of Northern Cyprus, which was established after the 1974 invasion and which is recognised as a country only by Turkey. The earliest known human activity on the island dates to around the 10th millennium BC. Archaeological remains include the well-preserved ruins from the Hellenistic period such as Salamis and Kourion, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

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. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea wit ...
