I just smelled them again

and they do smell a little like salt… perhaps A. bernardii is a good choice, what else would it be?

A. bisporus and A. vaporarius is the same, just synonyms.

But the “wild growing” A. bisporus is not common. In fact, I found it just three times till now.
It grows like his domesticated brother on nutrient-rich soils.

And it seems possibly to large to be A. bisporus

A. bisporus/vaporarius is another good option.

I wouldn’t exactly say that the soil is halophilous… though there is a walk way not too far away from it, which would be salted in the winter.

I don’t smell much Iodine,

It smells like the one you buy in the grocery store, A. bisporus which I suppose it may very well be, since it is growing in the lawn here in the city of Vernon.
I have a microscope though…

A. bernardii is halophilous.

bernardii has a distinctive odor of iodine.

Yes we have A. bitorquis but I think this is A. bernardii
