No distinct odors

My odor detector is pretty insensitive. Also, I could not elicit a bruising color reaction. It will be a long time before I eat anything I pick off the ground or tree stump.

What about odor?

Smell is one of the most important ways to ID your agaricus sp., esp. if you are considering it for the table. A pleasant (almond or anise or “mushroomy”, like a store-bought bisporus) smell spells ediblity (for some) and an off, phenolic/chemical/library paste odor spells a potentail loss of your lunch.

Campestris tends to be more compact, and they have distinctly pointed bases; check out this grasslands agaricus comparison by Dimitar Bojantchev…
