Cortinarius is a hard genus to identify. It doesn´t bruise to any color, it was already violet. The flesh was violet too, in cap and stem, I didn’t download the photo of it because the colour of the picture changed with the colour of the lamp of my kitchen. I have seen others similar to this, some of them with new, less new and old specimens but I don’t know if they are the same. I have identified them with glaucopus but I’m not sure, I’ll download those too and we will compare, ok?

I agree

that this obs might belong to the glaucopus group.. I have seen similar ones. And in that case, it excludes occidentalis too, which also is a purple staining species like purpurascens.

Have you sequenced any Cortinarius occidentalis? After all, C. occidentalis A.H. Smith is originally an american species, but Moser described a C. occidentalis var. obscurus for Europe. I’m curious, because I’m not sure how to tell it apart from purpurascens (there are several varieties of that one described too).

C. purpurescens stains purple when bruised. This is apparent in pictures of the gills, if any of the gills get broken. However, it does take a few minutes, so its possible to take a picture without seeing this. Also, the color of the cap in this picture is much darker than the ones I’ve seen and sequenced. I have only seen a few collections with the discolored fibrils on top of the cap. It would be good to have spores and KOH reaction. This collection fits the description of C. glaucopus that I have, but of course, that’s a group complex.
