 Amanita virosa
Commonly referred to as the Destroying Angel, Amanita virosa is a deadly poisonous fungus.
Amanita citrina var alba usually retains velar fragments on the cap; it has the sharp smell of new potatoes rather than a sweet odour.
Young caps of Amanita virosa could be collected by accident when gathering edible Agaricus species; gills of Amanita virosa are pure white, whereas the Agaricus species have gills that are initially pink and later brown.

Among the deadliest of all mushrooms are the large white destroying angels (A. bispongera, A. ocreata, A. verna, and A. virosa), which are found in forests during wet periods in summer and autumn.
Amanitas are medium to large, terrestrial and usually found in woods.
Most Amanita are mycorrhizal, and most commonly found amid or near trees with whose roots they form a symbiotic nutritional arrangement.

 Amanita phalloides
The Death Cap, Amanita phalloides, was known by the ancient Greeks and Romans to be a deadly poison.
There is, however, an all-white form of Amanita phalloides that is very similar in appearance to the Destroying Angel, Amanita virosa.
Amanita citrina (False Death Cap) generally has brownish-cream veil fragments on the cap, and a volval rim around its base rather than an open sack-like volva.

The Amanita specimen I took did not have or appear to have lost a “tattered” skirt indicative of the deadly Amanita virosa or “Destroying Angel” mushroom, however three others nearby did in fact have the skirt feature.
Most Amanitas have a volva and skirt and warts, which are all remnants of the universal veil which covers the whole mushroom when young.
But with the variability of the amanitas, we may never be able to tell from pictures and that is exactly why one should not eat questionable Amanitas.

The latter two species were defined in part by the fact that their basidia bore four spores, rather than the two spores on Amanita bisporigera basidia; they were further separated on the basis of spore shape, distribution, reaction to KOH, and the texture of the stems (smooth or shaggy).
Several mycologists, including Amanita expert Rod Tulloss, have suggested that the documentation of Amanita verna and Amanita virosa may be based in part on misidentified collections of a white form of Amanita phalloides.
However, the western Amanita ocreata is fairly clearly distinct; it is stouter, has somewhat larger spores, is found only on the west coast and in the southwest, and has inflated cells with thin walls in its flesh.

Amanita muscaria (Fly Agaric) – poisonings rare, possibly because its unique and obvious appearance make it easily identifiable; however, its long history of use as an entheogen and new reports suggesting it is less toxic than once thought may suggest otherwise.

The Amanita muscaria mushroom is also known as "Fly agaric" because of its (anecdotal) ability to attract and kill flies.
The fly agaric is related to some deadly mushrooms: the Amanita virosa (the "Destroying Angel"); Amanita verna and Amanita phalloides (the "Death Cap").
The symptoms may appear 30 to 60 minutes after the mushrooms are eaten and can last about four to six hours with a several hours lasing "afterglow".

 Erowid Amanita Vault : Myth Debunking - Liver Damage   (Site not responding. Last check: 2007-10-21)
Because A. muscaria and A. pantherina belong to the genus Amanita, the same genus that contains two deadly, liver-toxic mushrooms (Amanita phalloides and Amanita virosa), many people believe that the fly agaric mushrooms also contain liver toxins.
But the amatoxins and phallotoxins that are responsible for the deadly nature of A. phalloides, A. virosa, and several species of Galerina and Lepiota, and that cause a few deaths each year, are not present in A. muscaria or A. pantherina.
While it is probably good advice for the novice mycologist to avoid Amanita muscaria and Amanita pantherina because of the possibility of misidentification, this recommendation for caution should not be misread as evidence of the presence of liver toxins or a poisonous nature.

Instead, the Psilocybe semilanceata, being the only psilocybin-containing mushroom common in Slavic countries, is sought after for its hallucinigenic properties, the latter being more desirable with fewer side effects than those of A.
