constricta is common at Huck, it’s large, and it shows a similar reddening on the volva to pachycolea. The volva isn’t as thick, is constricted at the base and as Rod pointed out, often shows a gray lining.

Pachycolea usually has a much darker, two-toned umbonate cap, coupled with extremely long and deep striations at the cap edge.

Thanks Rod!

I had looked at constricta.But had a hard time noticing the grey signs. Thanks for the information.

The gills look as if they had turned gray with age.

Would you agree? This usually happens in species of sect. Vaginatae with weakly structured and graying volval sacks…or so I have come to expect. This suggests a determination something like A. constricta…even though the volval sac isn’t gray in all photos (but look at the cross-section, especially the upper part of the limb on the side of the stem where the limb is longest. That seems pretty gray to me.
