Amanita muscaria: chemistry, biology, toxicology, and ethnomycology.
The fly agaric is a remarkable mushroom in many respects; these are its bearing, history, chemical components and the poisoning that it provokes when consumed. The 'pantherina' poisoning syndrome is characterized by central nervous system dysfunction. The main species responsible are Amanita muscaria and A. pantherina (Amanitaceae); however, some other species of the genus have been suspected f...
متن کاملPigments of fly agaric (Amanita muscaria).
The complex pigment pattern of fly agaric (Amanita muscaria) cap skins has been studied by LC-DAD and mass spectrometry. Among the betaxanthins the corresponding derivatives of serine, threonine, ethanolamine, alanine, Dopa, phenylalanine and tryptophan are reported for the first time to contribute to the pigment pattern of fly agarics. Betalamic acid, the chromophoric precursor of betaxanthins...
متن کاملInvestigation of horizontal gene transfer in poplar/Amanita muscaria ectomycorrhizas.
Fine roots of forest trees form together with certain soil fungi symbiotic structures (ectomycorrhizas), where fungal hyphae are in intimate contact with plant cells. Due to root cell degeneration, plant DNA is released and could be taken up by the fungus. The possibility that horizontal gene transfer might result in a risk for the environment should be evaluated before a massive release of gen...
متن کاملEvidence for strong inter- and intracontinental phylogeographic structure in Amanita muscaria, a wind-dispersed ectomycorrhizal basidiomycete.
A growing number of molecular studies show that many fungi have phylogeographic structures and that their distinct lineages are usually limited to different continents. As a conservative test of the extent to which wind-dispersed mycorrhizal fungi may exhibit phylogeographic structure, we chose to study Amanita muscaria, a host-generalist, widespread, wind-dispersed fungus. In this paper, we do...
متن کاملMetallic Elements in the Fruiting Bodies of Fly Agaric Amanita Muscaria (l
The concentrations of some trace elements (such as Fe, Ag, Zn, Mn, Cu, Cd, Mg, Ca, Na, K) were determined in the fruiting bodies of Fly Agaric Amanita muscaria (L.: Fr.) Pers. The mushrooms were collected in Poland in 1999 and 2000. The samples of dried and pulverized mushrooms (separately the caps and the stalks) were wet digested with concentrated nitric acid in PTFE vessels under pressure in...
