Snake venoms are usually cocktails of larger proteins, not small cyclopeptides like amanitin.
They also tend to act differently: the main types tend to be hemolytic, rhabdomyolytic, and neurotoxic, often combined in one snake’s venom. Amanita poisoning is none of the above, though for each of those effects there are some other mushroom toxins that can act similarly (and still seem to be different in composition; for example, the nerve poison in Clitocybe dealbata, muscarine, is more closely related chemically to Sarin gas than it is to your typical snake venom).
i was just wondering if it was at all similar to the snake venom?
a cellular poison that inhibits RNA synthesis. The worst effects are in the liver but high doses can damage anything (and it doesn’t take much of one of these suckers to get a high dose, either).
Leave them alone or handle with great care.
is there a Neurotoxin found in these?
Since you have access to a scope and can take pictures through it, I’d ask if you could post images of the thick-walled hyphae and thick-walled inflated cells that are rather common in A. phalloides. I don’t think there is a web picture of this interesting character of A. phalloides. Recently Felipe Wartchow and I investigated about two thirds of the species in Amanita sect. Phalloideae. While relatively thick cells were not uncommon in most of the species, the thickest walls (considering maximum thickness) and the most plentiful thick-walled elements and the only case of thick-walled acropysalides that were found were all in A. phalloides. Don’t ask me why. The experiment should be repeated some day; however, The curious nature of thickened-cell walls in A. phalloides particularly sticks in my mind.
You were completely correct Rod Tulloss. I deleted the other picture.
looks whitish to me. Maybe my LCD monitor needs adjustment?
EDITED on 21 Nov. 2009: Should be noted that the picture with pileus margin apparently striate is no longer included in the current observation.
The first (especially) and the third pictures seem like A. phalloides to me. The cap margin is distinctly striate in the middle picture, which raises the question about whether this might be something different.
The center of the cap in the second pic looks orange to me — as if pigment were developing late (or had been washed out by rain in the area not under the large patch of volva. This suggests that it might be A. calyptroderma.
