We have both of the collections that you cited in your comment.

Very best,

records measurements smaller than actual. I believe a +17% conversion is very close to accurate. Judging from the photo (114780) I’d say the globose spores range between 7 and 9.5 mu. A few are subglobose, with q~1.1. This matches well with the spore size/shape for praecox.

Interestingly, growing very near to obs 114780 was obs 114779 , which looked very similar but with broadly elliptic spores. I think I had sent these collections to you.

I’ll check this same area again soon, but I’m not too hopeful this year. At this particular elevation there have been several mornings with low temps in the 20-24F range. Despite seemingly very favorable conditions this past week, virtually all the Amanitas (at this elevation) seem to have shut down for the year.

Hello, David.

Do you have spore measurements from that late season species under pine?

Very best,

should have a marginate basal volva. This reminds me of a late-season Amanita with variable basal volva that I have found under pine, obs 114780.
