3.Common conecap (Pholiotina rugosa)

Another species that shares these toxic compounds is Pholiotina rugosa, a fairly nondescript-looking, red-brown mushroom common in the Pacific Northwest, but found in Europe, Asia and North America too. Due to their similar conical brown caps, they are sometimes mistaken for Psilocybe, or magic mushrooms.

You would get much more than a bad trip with these, however. After about 6-24 hours after ingestion, you would experience some very nasty gastrointestinal symptoms, often initially mistaken for food poisoning, swiftly followed by liver failure and, if you are unlucky, eventual death.
