Agaricus Bisporus?

Agaricus Bisporus? (Not Bisporus)
I read about Bisporus having two color states. Is that most likely what I'm seeing here?
Is rubbing the best way to bruise?
I'm mostly concerned that I don't consume any Agaricus X.

If you cut the very base of the stem or rub the edge of the cap and look for dramatic yellowing you can determine whether you have one of the nastiest Agaricus, if it passes that test then smell a piece of freshly cut/crushed flesh. Most poisonous members of the genus smell unpleasant; kind of chemical-like or sometimes fishy. If yours smell ok (mushroomy, almonds, aniseed) and having made all other tests (spore colour, lack of bag/vulva at the base and veil/membrane texture and markings) you've eliminated most poisonous Agaricus. My opinion is that you have A.campestris however it's not an easy genus to id through photos alone with 100% certainty so would recommend a second opinion.

The yellowing has me concerned whether or not it can be Agaricus X. In which case how would I rule out type?
The pattern of growth fits the Bisporus description, going from pinkish/pinkish brown to brown/brownish black gills.
Thanks 61n63! Throwing down some tests now. There may be a couple different ones here.
Some of the gills are white, not pinkish really at all. But still wondering if that is part of how the color changes in this species.

Spore prints in the morning. The dark colored one definitely has a brownish/black print as evidenced by the shorter cap that was thoroughly dusted.

A. Abruptibulbus and A. Silvicola?
Only bad smell was from the large ones. Second opinion said smelled like old laundry that sat in the washer.

You most probably do have a couple of types, Agarcs.X will rapidly bruise a very bright yellow within seconds of cutting through the stem base or cap edge and smells like some kind of cleaning/sterilizing product. Ideally things like smell and colour change are checked in the field as I believe they're the sort of features that can become less pronounced as the mushroom ages.
But those are the salient features that can help ID Agaricus, I'm v.reluctant to offer any definitive ID on Agaricus via a forum but hope this has been useful. Also, (sorry if I'm telling you something you already know) but really be careful with those young ones with white gills and make sure a bag or vulva wasn't at the base of the stipe.

Not too sure the color of the prints can be differentiated without microscopy, if in fact they are different.
The yellowing was also mentioned as a trait of several other A. Species. Including Abruptibulbus and Silvicola. I did produce yellowing however.
Can someone direct me to a reference on this "bag/vulva?"

If you type Amanita virosa vulva into google you'll see what I mean, it's a kind of bag/sack that the mushroom emerges from at the base of the stem. Agaricus don't do this whereas Amanitas (not all of them) do. Worth familiarizing yourself with Amanita virosa if you haven't yet (apologies if you have already), particularly if you want to pick young Agaricus.

My recent experience with store bought crimini was fishy smell. Does the species smell like fish or we have a bad fruitbody?

Smell (or interpretation of it) is a very subjective thing. Some people can smell the aniseed or chemical smell of various Agaricus species and some can't. And some people smell something entirely different. To me A. bisporus from the shop smells like nothing apart from a vague earthy mushroom scent. Certainly not like fish!

The fishy smell could have been originated due to old fruit-bodies but am not sure when was the fruit-bodies plucked as there is no date on the store bought package.
Experts may elaborate.

This is what i mean. They do become more strongly smelling but it's not something I'd ever call fishy myself. Although i can see why someone else would. This is why it's not a reliable test.

I wouldn't eat an Agaricus bisporus that smelt of fish personally, sounds like it may be rotten. Also countrymushroom77, just to add, I should have typed 'Volva' NOT 'Vulva' which is something else entirely .

A freudian slip if I've ever seen one.
