Observation separated

The first 6 pictures are from one spot, the next 4 were from ten feet away. I created a separate observation for those since they might be a different species. The specimen I saved and did microscopy on is the one in pic # 2. I just checked KOH reactions on that mushroom and the results convinced me that the observations needed to be separated. KOH on the cap changed it slightly darker brown – basically did nothing, but on the stem it turned a rose pink color, which faded to brown after 30 minutes. Good eyes Irene!

The bulb.

The bulb dear. Yes, it looks on colors and stature, but the bulb is not marginated. And that’s a huge difference.

Strange

On the first 6 pictures it looks like a perfect european Cortinarius arcuatorum (don’t think it grows with Abies though), the rest looks like something else..

This is in the C. napus clade, but it doesn’t quite look look like the Euro C. napus. Ours has bluish gills, theirs white… In fact we have two similar species in coastal California, one is described, the other not. Here is the described one. I will drop a photo of the other one when I have time. Save some material, hey!!

Nice shots of cortina
