I uploaded pictures of the lower stipe and this was originally identified at shroomery with some old lackluster pictures a while ago, though having forgotten the name mushroom expert helped remind me.

And I looked through the Coprinopsis atramentaria observations earlier and found a few more that look like this. Including one from Argentina and another from Iran. http://mushroomobserver.org/19090?q=4EJ4 & http://mushroomobserver.org/6038?q=4EJ4

Edit: And another in Chile – http://mushroomobserver.org/18460?q=4EJ4

and I can see the veil ridge on the lower stipe…if so, then I suspect there are other west coast collections for this species, like this one:

I’ve uploaded the closest I have to a picture of the lower stipe. There were many pins so I’ll get more pics tomorrow.

Also, these have been fruiting every time I have visited this location since early last fall. Though, this is only the first time I got satisfactory pictures.

Need close up off the lower stipe.

Do you have any photos more of the lower stipes there? Need to see the floccose scaling, and a veil ridge there on the lower stipe.

Didn’t know these appeared in California… I’ve seen them in Europe.
