Although many people have a fear of mushroom poisoning by "toadstools", only a small number of the many macroscopic fruiting bodies commonly known as mushrooms and toadstools have proven fatal to humans. This list is not exhaustive and does not contain many fungi that, although not deadly, are still harmful.
The mushrooms' characteristics are quite common, making them difficult to identify, which often leads to fatal poisonings. Young examples of the species often have a veil between the cap of the mushroom and the stem. This veil looks like a cobweb, hence the name. The veil however partially or completely disappears in older specimens.
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 ] It is also the deadliest mushroom worldwide, responsible for 90% of mushroom-related fatalities every year. [ 10 ]
This is the basis for the common recommendation to slice in half all puffball-like mushrooms picked when mushroom hunting. Mushroom hunters recommend that people know how to recognize both the death cap and the destroying angel in all of their forms before collecting any white gilled mushroom for consumption.

The mushroom was sometimes described as edible (though not tasty) until 1999. [ 25 ] [ 33 ] [ 53 ] Fries described it as venenatus , meaning "poisonous", in 1821. [ 6 ] Considering the species edible, David Arora speculated that it may have been confused with similar-looking but definitely poisonous species of Omphalotus . [ 25 ]
This mushroom has a fleshy pale yellow, or sometimes white, cap from 4–10 centimetres (1 + 1 ⁄ 2 –4 inches) across, covered in irregular patches. The gills and flesh are white. There is a large volva at the base of the 6–8 cm (2 + 1 ⁄ 2 –3 in) tall stem, which has a clear ring. The mushroom has a smell of rapeseed or potato. [2]
Inosperma erubescens (formerly Inocybe erubescens, also formerly named I. patouillardii), and also commonly known as the deadly fibrecap, brick-red tear mushroom or red-staining Inocybe, is a poisonous basidiomycete fungus, one of many in the original genus Inocybe and one of the few known to have caused death.
