Galerina
Galerina sp. are potentially deadly mushrooms that can be easily confused with psilocybe sp. Mushroom hunters who are not careful can also confuse Galerina sp. with Armillaria sp. even though the resemblance is superficial.
Galerina have a convex to conic cap, stirate and glabrous. The spore print is brown. The stipe is long and slender and there is a hairy veil.
Some species of Galerina contain alpha-amanitin which is the deadly peptide poison found in the [[amanita] mushrooms such as the destroying angel. This poison has the wonderful property that you do not feel much until it has been absorbed into the blood stream and concentrated in the liver and kidneys. Once all hope of removing the poison from the stomach and intestines has passed, the victim will then start to get sick. By this time the course of the poisoning is cast in stone and often the only way to save the patient's life is through a transplant.
Galerina sp. are so remarkably similar to some species of psilocybe that a microscope is needed to see how the spores are attached to the basidia.
