Galerina autumnalis

Delayed-onset mushroom poisoning, usually caused by Amanita phalloides, A virosa, Galerina autumnalis, or G marginata, manifests its first symptoms 6-12 hours after ingestion. Although the initial symptoms usually include nausea and vomiting, the major toxicity involves hepatic and renal cellular injury by amatoxins that inhibit RNA polymerase. Atropine is of no value in this form of mushroom poisoning (see Chapter 58). 

IMPORTANT NOTE this species can easily be confused by the novice with the deadly species Galerina autumnalis, with which it sometimes clusters. The most potent psilocybian mushrooms grow on wood chips, and so anyone hunting for them should know how to identify the poisonous Galerina. 

Delayed gastroenteritis and liver failure Amatoxins (See p 273) Amanita phalloldes, A ocreata, A verna, A virosa, A bisporigera, Galerina autumnalis, G marginata, and some Lepiotaan6 Conocybe species. Delayed onset 6-24 h vomiting, diarrhea, abdominal cramps, followed by fulminant hepatic failure after 2-3 days.
