Isognomon Legumen
(For the tree oyster mushroom, see ''Pleurotus ostreatus''.) ''Isognomon'' is a genus of marine bivalve mollusks which is related to the pearl oysters. ''Isognomon'' is known in the fossil record from the Permian period to the Quaternary period (age range: 254.0 to 0.012 million years ago). Fossils of species within this genus have been found all over the world. Taxonomy This genus is placed in the family Isognomonidae. However previous molecular phylogeny studies have shown that these tree oysters belong in the family Pteriidae. Description These oysters grow to be about in overall length, producing a highly irregular shell with a blue-gray and often heavily encrusted exterior but a smooth and pearly white interior. They use their byssus to completely immobilize themselves to the roots of mangrove trees, corals, and other substrates. It is because of the preference for mangroves that these are sometimes called tree oysters [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleurotus Ostreatus
''Pleurotus ostreatus'', the oyster mushroom, oyster fungus, or hiratake, is a common edible mushroom. It was first cultivated in Germany as a subsistence measure during World War I and is now grown commercially around the world for food. It is related to the similarly cultivated king oyster mushroom. Oyster mushrooms can also be used industrially for mycoremediation purposes. The oyster mushroom is one of the more commonly sought wild mushrooms, though it can also be cultivated on straw and other media. It has the bittersweet aroma of benzaldehyde (which is also characteristic of bitter almonds). Name Both the Latin and common names refer to the shape of the fruiting body. The Latin ''pleurotus'' (side-ear) refers to the sideways growth of the stem with respect to the cap, while the Latin ''ostreatus'' (and the English common name, oyster) refers to the shape of the cap which resembles the bivalve of the same name. The reference to ''oyster'' may also derive from the slipp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
