Helvella Elastica
''Helvella elastica'', commonly known as the flexible Helvella, or the elastic saddle, is a species of fungi in the family Helvellaceae of the order Pezizales. It is found in Asia, Europe, and North America. It has a roughly saddle-shaped yellow-brown cap atop a whitish stipe, and grows on soil in woods. Another colloquial name is the brown elfin saddle. Description The fruit body of the fungus is grayish or olive-brown, saddle- or mitral-shaped (i.e., resembling a double mitre) and is attached only to the top of the stipe; it may be up to wide. The underside is white. The stipe is white, solid or filled with loosely stuffed hyphae, has a smooth surface, and is up to long by thick. The flesh of ''H. elastica'' is brittle and thin. The odor and taste of this mushroom are not distinctive. Microscopic characteristics The spores are oblong to elliptical in shape, translucent (hyaline), contain one central oil drop (''guttulate''), and have dimensions of 18–22 by 10â ...

Jean Baptiste François Pierre Bulliard
Jean Baptiste François Pierre Bulliard (also Pierre Bulliard; 24 November 1752, in Aubepierre-sur-Aube Haute-Marne – 26 September 1793, in Paris) was a French physician and botanist. Bulliard studied in Langres, where he became interested in natural history, and afterwards a position was obtained for him in the abbey in Ville-sous-la-Ferté, Clairvaux and later he moved to Paris where he study medicine. There he also practiced as a physician. He tutored the son of General :fr:Claude Dupin, Claude Dupin (1686-1769). He was an able draughtsman and also learnt to engrave. He invented a way of printing natural history plates in colour and used the method in his own publications. In 1779 he commenced a work on the poisonous plants of France. It was seized by the police on the grounds that it was a dangerous work. Bulliard's ''Dictionnaire Elémentaire de Botanique'' (1783) contributed to the spreading and consolidation of botanical terminology and the Linnaean taxonomy, Linné ...

Gyromitrin
Gyromitrin is a toxin and carcinogen present in several members of the fungal genus ''Gyromitra'', like '' G. esculenta''. Its formula is . It is unstable and is easily hydrolyzed to the toxic compound monomethylhydrazine . Monomethylhydrazine acts on the central nervous system and interferes with the normal use and function of vitamin B6. Poisoning results in nausea, stomach cramps, and diarrhea, while severe poisoning can result in convulsions, jaundice, or even coma or death. Exposure to monomethylhydrazine has been shown to be carcinogenic in small mammals. History Poisonings related to consumption of the false morel '' Gyromitra esculenta'', a highly regarded fungus eaten mainly in Finland and by some in parts of Europe and North America, had been reported for at least a hundred years. Experts speculated the reaction was more of an allergic one specific to the consumer, or a misidentification, rather than innate toxicity of the fungus, due to the wide range in effects se ...

Fungi Of Asia
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'' (''true fungi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
