Yes looks like A. putaminum.

I had thought that perhaps this was A. praecox group where veil remnants had washed away because of recent weather. But now that I see the Mykoweb picture of A. putaminum (which is not in references I own), I agree that this looks like A. putaminum.

I agree (sort of)

I agree that this doesn’t look like A. praecox and is probably A. putaminum, but I’d caution against the use of the presence/absence of a partial veil to distinguish A. praecox. In my experience (Arora mentions it also), many collections of (presumably) A. praecox lose their partial veils very quickly.

Not A. praecox

With no veil/annulus.
