Noah suggested maybe A. bisporus for the smaller one too, and it does resemble the dried up ones I saw a few days ago growing right next to some equally dried A. fuscovelatus.

I sincerely doubt

the lower one is not A. fuscovelatus – probably A. bisporus, the wild form.

these are not…

that we were only looking at photos, and some ambiguous ones to boot.

The large cap is 5 cm and the small one is 3 cm in diameter.

These were much smaller…. But I really don’t see how A. lilaceps and A. fuscovelatus look similar, regardless of size. I know you and Christian seemed to think so to some degree, but I don’t see it.

Also, Darv, I have seen upwards of 3 or 4 species growing in the same small Cypress Grove, some times nearly next to one another. I noticed it yesterday that the young one didn’t look like A. fuscovelatus but the older one definitely was. Maybe there are two species in this observation.

they look smaller than the A. lilaceps recently posted here…approx. size of your caps were…?
