Think this observation has the best name on it at this point. Always learn new things with other observers input. Appreciate this fine community of people.

populiphila occurs w/cottonwood and aspen

it has a fairly discrete thimble-like volva (not a long loose membranous one like you show here), that readily falls off. And the cap is tannish, not yellow.

We have ridiculous amounts of unnamed species of grisettes in AZ, and probably just about everywhere else, too.

I did not personally see a yellow capped grisette in AZ last week, altho I did see white, bronze, orange, gray, pink and piebald!

nice find.

This species lacks the staining of populilphila and appears to have a yellow cap.

I don’t think this is populiphila.

Was it collected near cottonwoods or aspen?

The are yellow-capped Vaginatae in the mountains of the southwest.

How about sp-NM02?

Also, it is sometimes useful to use the illustrated checklist for AZ and NM. In this case, I think it is useful.


Sorry that I have been so snowed under that I have not been on MO very much lately.

Very best,

for your species proposal. I had never even heard of this species until you proposed it. I will check to see if I have any additional photos I can add to this observation which may reveal any other characteristics of this specimen. Thanks again for your help. This was found at a little over 7,000’ elevation.
