The mushroom belongs to the same section (Phalloideae) and genus (Amanita) as several deadly poisonous fungi including the death cap (A. phalloides) and several all-white species of Amanita known as "destroying angels": A. bisporigera of eastern North America, and the European A. virosa. "Death angel" is used as an alternate common name.
The large fungi, responsible for about 90% of the world’s mushroom-related fatalities, primarily grow at the base of trees along the coasts of California, Oregon, New Jersey and other coastal ...
A very close relative of P. cyanescens is Psilocybe allenii (described in 2012), formerly known as Psilocybe cyanofriscosa, a mushroom found in California and Washington [13] [11] It can be distinguished by macromorphological features and/or sequencing of rDNA ITS molecular marker.
Psilocybe aztecorum is a species of psilocybin mushroom in the family Hymenogastraceae.Known from central Mexico, Arizona, California, Oregon, Colorado, Canada, India and Costa Rica, the fungus grows on decomposing woody debris and is found in mountainous areas at elevations of 2,000 to 4,000 m (6,600 to 13,100 ft), typically in meadows or open, grassy conifer forests.
Amatoxins, the class of toxins found in these mushrooms, are thermostable: they resist changes due to heat, so their toxic effects are not reduced by cooking. Amanita phalloides is the most poisonous of all known mushrooms. [6] [7] [8] It is estimated that as little as half a mushroom contains enough toxin to kill an adult human. [9]
The genus Amanita was first published with its current meaning by Christian Hendrik Persoon in 1797. [1] Under the International Code of Botanical Nomenclature, Persoon's concept of Amanita, with Amanita muscaria (L.) Pers. as the type species, has been officially conserved against the older Amanita Boehm (1760), which is considered a synonym of Agaricus L. [2]

The jack o'lantern mushroom is poisonous; while not lethal, consuming this mushroom leads to very severe cramps, vomiting, and diarrhea. [5]The toxic ingredient of many species of Omphalotus is a sesquiterpene compound known as illudin S. [8] This, along with illudin M, have been identified in O. nidiformis.
