I don’t trust my own visual ID in Vaginatae. There are too many undescribed taxa. I’m still sorting out the microscopy (when I get time)…don’t know if I’ll feel comfortable with these critters in this lifetime. Tremendous improvements in understanding have come about in the last two decades, but there are so many unnamed taxa.

Good luck.

Thanks Rod!

I still get confused with these.

pachycolea?

The pileus is uniformly colored rather than having a dark zone at the inner ends of the striations. The volva seems rather weakly structured. The volva has no orangish or ochraceous staining. For these reasons, I wonder if this can be pachycolea.

Reminds me a little bit of 60195. In that case, the volval sac remains at the base of the stem, with no remnants on the cap.

On that page there are some links to other possibilities that I posted.
