Recognized by sight: Growing with wood chips, mild pleasant odor

Recognized by sight: not arvensis tho: wood chip rather than grass habitat, and I don’t see yellow on fruit bodies anywhere.
Arvensis smells of anise or almonds to the nose…not just not bad, or vaguely “mushroomy”. you may be one who can’t smell the library paste smell of phenol, which complicates Agaricus ID.

Yep it was, nice to find these. As to smell it had a ever so slight almond or sweet and not a phenolic.If you look at the fourth picture there is a place on the cap where it was scraped, no yellow.

is that a piggyback mushroom its cap?

imagining that this is actually A. arvensis, given the wood chip habitat, lobed cap, and tortuous/shiny stem. Sure it’s not one of the toxic yellow stainers? Some people interpret the phenol odor as a nice smell.
