If there is another flush of Inocybe haemacta, I will take photos of cut
in two specimens, to show the greenish-blue staining.

I don’t know if Inocybe calamistrata is really hallucinogenic,
but there are people where I live who are crazy enough to
experiment with Inocybes. And they say that Inocybe calamistrata
is clearly hallucinogenic but causes nausea. Inocybe calamistrata
is widespread (Europe, North, Central and South America).
Maybe genetically different strains do exist.

Thanks for the info. Hallucinogenic Inocybes are rare; There are six according to Brandon Matheny.

Are you sure I. calamistrata is one of the hallucinogenic species? It does not taste like other hallucinogenic species and I have heard that it is toxic. I find it all the time in Mexico and occasionally in California.

I added one of your images to the wikipedia article on Inocybe haemacta.

Different smell

The smell is very different to other Inocybes. It smells like urine;
not spermatic like many other Inocybes.

This species stains greenish-blue, if the stipe is cut in two.
But the greenish colors are clearly dominant.

After several hours the greenish-blue color turns into brown.
I don’t know if the color fades after drying. I have never dried any specimens.

I know two places for many years where Inocybe haemacta is growing.
One under a limetree in grassland, the other on a cemetery under oaks.

The species was identified by a professional mycologist in our mushroom
club, where we meet every Monday evening. All four species of hallucinogenic
Inocybes (haemacta, corydalina, aeruginascens, calamistrata) look clearly
different and are easy to identify if you ever have had them in your hands.
The urine-like smell of Inocybe haemacta is very characteristic.
Another characteristic is the rough texture of the cap (in contrast
to Inocybe corydalina and Inocybe aeruginascens).

Odor

This looks a lot like some of the Inocybes I have found in Mexico.

What does it smell like?

Does this species stain blue, or is it just blue?

Does the blue color fade as it dries?

How did you determine that it is I. haemacta?
