Agaricus sp. with foetid scent

Hello Steve,

Agaricus should be safe, according to the form an colour of spores.

Now, you have to find out the right section/subgenus. For this, there is KOH-Test on Pileipellis (reaction nil or yellow), as well Schaeffer-Test (paint a cross on pileipellis by one line with HNO3 and the other with Anilin, the middle of the cross will be striking orange when Schaeffer-reaction is positive). Then you go into the right section. But then the difficulty begins.

Let's put it this way: That's where the trouble starts rather than the difficulties.

Concentration of HNO3: as fat as available. When I open my bottle with HNO3, it smokes.

I consider the KOH reaction as negative. Therefore, according to KIBBY, The Genus Agaricus In Britain, it's neither a Minores nor an Arvensis nor a Xanthodermatei. When Schaeffer reaction should be positive, it's a Bohusiae or a Spissicaules. When Schaeffer should be negative, it's an Agaricus, a Bivelares, a Chitoinoides or a Sylvatici.

Hi Steve

Zitat von Steve_mt

I do not have the other Aniline and Nitric Acid (what concentration the acid should be ? )

Since handling aniline and nitric acid can be quite problematic, as the substances are dangerous and toxic, I use sulfanilic acid instead, as described here (unfortunately only in German):

(Since the links are still not working properly, I have attached it as a PDF.)

As far as I know, it should have the same effect and be far less problematic.

Kind regards,

Benjamin
