I Found One Too

I just wanted to add my voice to the mix. I found this exact mushroom, in Bannockburn, IL in Lake County. It was growing on the ground by an oak tree. The top of the mushroom looks a bit like a pitted potato.

It has a very aromatic smell and has stayed nice for several days.

Based on this website ( It appears that this mushroom could potentially have a different subgenus. I am by no means an expert, but just another observer. There is a list at the bottom of that page that has a whole bunch of subgenus, but I haven’t looked through them.

Here are the pictures of the one I found

Cortinarius sp

Thank you for the input. I knew it was Cortinarius but guessed on sp after reading in Aura’s book, nothing quite fit.

a species with oak that we call Cortinarius eucaeruleus in Europe. I don’t know if you have the same in Illinois. It’s definitely not violaceus.
