DescriptionIn biological naming conventions, the abbreviation cf. (which in Latin means compare) placed between the genus name and the species name indicates that the specimen is confidently identified at the genus level, but the actual species level identification cannot be certain. In this case, “Amanita cf. bisporigera” indicates that the specimen is in the genus Amanita and believed to be Amanita bisporigera but not with 100 % certainty.

Amanita bisporigera G. F. Atk. Belongs to a very toxic group of mushrooms commonly known as “destroying angels”. Amanita bisporigera along with Amanita phalloides (death cap) account for the majority of deaths due to mushroom poisoning. The toxin they produce – amatoxin – irreversibly destroys liver and kidney tissues and leads to the death of the person that ingested it. The destroying angel can be easily mistaken for edible fungi. This species forms mycorrhizal associations with oaks and is widely distributed in eastern North America.
