Pholiotina rugosa
Conocybe filaris · Deadly conocybe · Fool's conecap
A small brown lawn mushroom with a ring, growing in exactly the grassy habitat people search for liberty caps. Formerly called Conocybe filaris, which is still the name most references use. It is the lawn counterpart to Galerina's wood-chip trap.
If you may have eaten this: get to an emergency department now and say you may have eaten an amatoxin-containing mushroom. Don’t wait for symptoms, the symptom-free window is part of the poisoning, not a sign you’re fine. Bring a sample if you can. Treatment works far better before liver damage sets in.
What it does
- Toxin
- Amatoxins, as in Galerina. Same mechanism, same destruction of the liver, same failure to be destroyed by cooking.
- Time to symptoms
- 6 to 24 hours delayed, then the same biphasic course as Galerina.
- Outcome
- Liver failure. Fatal. Small, so people take several without thinking about it.
Decisive characters
Each of these settles the question on its own. If one says no, the answer is no, regardless of what everything else says.
Supporting characters
Useful corroboration. Not sufficient alone.
