Hey Martin!
Thanks for the comments! There is one mushroom there that has yet to come out of its veil yet. Speckled hood is still on. I will keep checking on it. I originally found this mushroom yesterday, but went back to check on the young one today and it has yet to reveal itself. I would love to decipher exactly what it is; I will bring it in next monday. If I am to pull it friday, not sure how fresh it will be come monday, but there will be spores…

Bingo!

Erin – Because of the volva, clearly seen in the 1st photo, I would say that you are right, at least about the genus. That is a home run for sure! I have never found one. It would be a great subject for a description if you can manage one. It looks like they are a bit past their prime. There are only 15 sequences for this species on GenBank and only 4 of them indicate that the ITS is included. It would be a good one – especially if you can find some fresh ones. Of course they might come back next year. It would be nice to have the sequence when that happens. I can see the color of the spores on the gills and on the cap of the last photo. Spore looks like a relative of Pluteus (which Volvariella is) to me, but it can’t be Pluteus with the volva. Use this website for taxonomy issues:
