Dear Neil Ji, I think this is *Amanita pantherina *commonly known as ‘panther mushroom”. This is a toxic species. The colour of the cap may vary from dark brown to nearly yellow in colour with small white to creamish warts on the upper-surface of the cap. Other two distinguishing points are volva is rolled like a collar at the base and the stipe is narrowing at the apex and broad at the base. All the character can be observer from your photos. The toxin fond in this mushroom is Muscarine.
• Muscarine binds to some receptors of parasympathetic nervous system • It does not cross the blood/brain barrier and as such cannot be responsible for any effect on the central nervous system • It is heat stable • Lethal dose ranges from 40mg to 180mg *Clinical Symptoms* • Onset of symptoms in 5 – 30 minutes after ingestion of mushroom • Prespiration • *S*alivation • *L*acrimation SLUDGE SYNDROME. • *U*rination • *D*efeacation • *G*astrointestinal distress • *E*mesis • Miosis, Blurred vision • Intoxication subsides within two hours • Deaths are rare, but may result from cardiac or respiratory failure in severe cases *Treatment* • Administration of atropine • Inducing emesis to empty stomach of all mushroom fragments I will also like to say to Raghu Ji that POINOUS mushrooms have no feature or characters which separate them from edible species. The most common myths regarding poisonous mushrooms are • Having bright, flashy colours (some very toxic species are pure white) • Poisonous mushrooms smell and taste horrible (Some taste delicious, reported by victims) • Tarnishes silver spoons when touched (*Amanita phalloides *does not blacken silver) • Lack of snail or insect infestations (a mushroom might be harmless to invertebrates, but could be toxic to humans) • Any mushroom becomes safe for eating, if cooked enough (the chemical nature of some toxins are very stable, even at high temperature) *THIS IS A GENERAL RECOMMENDATION ………………….* • Identify every mushroom collected in the field before consumption • Strictly avoid any mushrooms which look like *Amanita, *little brown mushrooms and false morales. • Some people are allergic to the safest mushrooms. The first time you try a new wild mushroom, try it in a small amount and wait for a day before eating more • As with other foods, rotting mushrooms can make you ill. Eat only fresh mushrooms • Most wild mushrooms should not be eaten raw, since they are difficult to digest. They should be well cooked before consumption as it will destroy the heat labile toxins present in them. • Alcohol consumption should be avoided when eating previously untried wild mushrooms *There are no simply guidelines to identify poisonous mushrooms. A common rule followed by mushroom hunters is:* *WHEN IN DOUBT THROW IT OUT!! * Regards Tanay * * On Fri, Oct 29, 2010 at 3:21 AM, Gurcharan Singh <[email protected]> wrote: > Thanks Raghu ji for interesting details. > > *-- > Dr. Gurcharan Singh > Retired Associate Professor > SGTB Khalsa College, University of Delhi, Delhi-110007 > Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018. > Phone: 011-25518297 Mob: 9810359089 > http://people.du.ac.in/~singhg45/ > * > > On Thu, Oct 28, 2010 at 11:32 AM, Pankaj Kumar <[email protected]>wrote: > >> Beautiful pictures....TOADSTOOL, I have never heard that name before.... >> Thanks for sharing. >> Pankaj >> >> >> On Thu, Oct 28, 2010 at 11:58 PM, raghu ananth <[email protected]>wrote: >> >>> Hi Neil, >>> >>> Nice picture set of larger mushroom kinds, Am yet to see mushrooms of >>> that size.
